essential oils diffusers and affect on asthma

What Asthma Patients Need to Know About Essential Oils and Diffusers

Essential oils have been around for centuries, but a new interest is sweeping the market. Maybe you’ve picked up a bottle in the store or attended an essential oil party in the home of a friend. While many benefit claims are unsupported by the Food and Drug Administration (FDA), companies and those who use essential oils claim they help with several conditions including depression/anxiety, headaches, congestion, hormone imbalance, cold sores, high blood pressure, and much more.

What are essential oils?

Essential oils are highly concentrated herbal remedies derived from plants. For example, lavender, eucalyptus, peppermint, orange, and tea tree oil. Many of these oils and others are packaged in blends or sold as single oils for aromatherapy. Oils can be diffused into the air, massaged into the skin, or ingested in a capsule.

Is there evidence that essential oils help asthma?

While individuals and companies (within certain limits) claim essential oils may help a variety of conditions, there is no evidence that essential oils can help asthma. In reality, breathing in the particles released by the oils, or any strong fragrance (natural or otherwise), may trigger bronchoconstriction (i.e. asthma symptoms).

Essential oils are highly concentrated and emit strong odors due to volatile organic compounds (VOCs), including terpenes, toluene, and benzene, when diffused in the air. Terpenes are associated with increased shortness of breath, especially in the evenings (i.e, nocturnal breathlessness)  bronchial hyperresponsiveness, and peak expiratory flow variability in patients with or without asthma. There have been anecdotal claims of respiratory issues for people with or without asthma due to airborne irritants from a variety of diffused essential oils

VOCs within the diffused oils can affect indoor air quality causing a similar pollutant effect as air fresheners, scented candles, and incense. Poor indoor air quality can worsen existing respiratory symptoms from allergies, asthma, and other respiratory illnesses. In addition, some essential oils are harmful to inhale or can irritate the skin. Use on young children may cause severe irritation or could be poisonous if ingested.

Are alternative treatments safe?

Essential oils are not regulated the same way prescription medications are for asthma. Alternative medicine treatments do not undergo scientific review and may not be safe.

There currently is no scientific evidence that supports essential oils help people with asthma. In fact, diffused oils may cause greater harm to those who suffer from asthma. The FDA has issued warning letters to essential oil companies who make unsubstantiated claims about their uses.

Talk to your doctor before substituting an alternative medicine for an asthma medicine prescribed by your doctor. While the oils are considered “natural”, they release VOCs which have been associated with increased asthma symptoms.

Before substituting essential oils for medications, consult with a trained physician. If you suffer from asthma, get clear answers from the Allergy & Asthma Specialists of North Florida.

Understanding Outdoor Allergens

How can floating particles in the air cause such unfavorable allergic reactions? Outdoor allergens can lead to hay fever and a range of allergy symptoms. These symptoms often including runny nose, sneezing, congestion, and itching of the eyes, ears, nose, throat, and roof of the mouth. The causes of these reactions are typically from mold spores or pollen in the air.

Your body’s immune system controls how it defends itself. If you are allergic to pollen, your immune system thinks pollen is an invader and overreacts by producing antibodies known as Immunoglobulin E (IgE). When these antibodies travel to cells that release chemical, an allergic reaction occurs.

Don’t let outdoor allergies get the best of you. Get to know the two most common outdoor allergens and how to avoid them.

Mold Spores

Mold spores can exist almost anywhere and even float in the air. Molds are tiny fungi similar to mushrooms but without roots, stems, or leaves. Outdoor mold spores increase when temperatures rise in the spring. In the United States, outdoor molds peak in July in warmer states and October in colder states. Mold is present in the South and on the West Coast year-round.

Tips to Avoid Exposure to Outdoor Mold Spores

  • Avoid going outdoors on rainy or windy days when mold may be in the air.
  • Keep rain gutters and drains clear of leaves and debris. Make sure downspouts flow water away from the house.
  • Avoid yard activities or wear a mask when mowing the lawn, raking leaves, or gardening with compost.
  • Keep excess leaves, compost, and grass away from areas near your home.

Plant Pollen

Pollen are tiny particles that fertilize plants. Many plants have flowers that produce powdery pollen which can be easily spread by the wind. Colorful flowers such as roses rarely cause allergies and rely on insects to transport pollen for fertilization.

Plants that release pollen have a specific period of pollination during the year and weather can affect the amount of pollen in the air. Seasonal allergic rhinitis is typically caused by tree pollen in early spring. Grass pollen can cause allergy symptoms in late spring and early summer. Hay fever is caused by weed pollen in late summer. In warmer areas, pollen can be present year-round.

Tips to Avoid Exposure to Outdoor Pollen

  • Stay indoors when pollen counts are high. Keep an eye on local pollen reports or download a weather app for daily pollen counts in your area. Pollen counts are typically lowest just after sunrise and highest in the afternoon.
  • Mow your lawn often, and if possible, have a family member or friend do it for you. If you must mow, use antihistamines before you mow and wear a dust mask.
  • Keep the windows and doors of your house or car closed all day. Use air conditioning to avoid pollen coming inside.
  • Vacation during peak pollen season to a location where the plants you are allergic to don’t grow.

Treatment for Outdoor Allergens

If outdoor allergies continue to be a struggle, see an allergist for relief from seasonal symptoms. An allergist can determine which allergens, if any, are causing your symptoms and develop a treatment plan to help you feel better. Your personalized plan may include ways to avoid an allergen and medications for temporary relief.

If symptoms persist, your allergist may recommend allergy shots (immunotherapy). This involves regular injections with gradual increases in doses. The process helps your immune system become more resistant to an allergen and lessen symptoms over time.

allergy and sinus headaches

Allergies and Headaches: What Patients Need to Know

Make an Appointment to Get Relief Now

It’s estimated that nearly 70-80% of Americans experience headaches. Those who suffer from allergies already have to deal with rashes, difficulty breathing, congestion, and a host of other unpleasant side effects. Yet, sinus headaches and even migraines can also be added to this list of allergy side effects.

While headaches aren’t typically life-threatening, they can affect your quality of life. If you suffer from allergies and headaches, here’s what you need to know and how to treat them.

Symptoms of a Sinus Headache

Your sinuses are hollow air spaces which allow the exchange of air and mucus. These passages are located behind the eyes and the bridge of the nose, in the forehead, and inside each cheekbone. Any secretions in the sinus cavities typically drain into the nose.

Sinus pain is caused when the sinuses are swollen, filled with fluid or the openings are obstructed. Any obstruction stops normal drainage and causes pressure to build up inside. Many times, the pain is in relation to the affected sinuses. Sinusitis pain can be dull or intense and often is worse in the morning hours after you wake up.

Allergy Headache Triggers

Allergies can trigger sinus pressure and headaches from several sources. The most common allergens and triggers include:

  • Certain foods
  • Dust
  • Pet Dander
  • Pollen
  • Sinus congestion
  • Smoke
  • Stress

Managing Allergy Headaches and Triggers

The key to managing your allergies and reducing headaches is limiting exposure to allergens and triggers.

  • Stay indoors and keep the windows shut when pollen counts are high.
  • Wear glasses or sunglasses outdoors to keep pollen from getting in your eyes.
  • Use the air conditioning in your home and in your car. Make sure to change out the air filters regularly and keep AC units clean.
  • Use mite-proof covers in your bedroom for pillows, comforters, and mattresses to reduce exposure to dust mites.
  • Keep your home’s humidity at 30-50% to reduce exposure to mold. Clean your kitchen, bathrooms, and basement regularly and use a dehumidifier in damp, humid places.
  • Wash floors with a damp mop or rag to avoid dry-sweeping or dusting.
  • If you are allergic to a pet, keep them outside of your home. If a pet must be kept indoors, keep it out of the bedroom so you are not exposed to allergens while you sleep.
  • Replace carpeting with hardwood, tile or linoleum to reduce dander in the home.

Many sinus headache triggers are airborne and difficult to avoid. Discuss your options with your allergist to decide which treatment options are best for you.

Treatment for Allergy Headaches

If your allergy headaches persist, your allergist may recommend one or more of the following treatments to offer relief.

  • Pain Relievers: Advil (ibuprofen) and Tylenol (acetaminophen) can offer short-term relief for sinus pain.
  • Oral & Nasal Decongestants: Available in over the counter (OTC) medications, these can treat nasal congestion and relieve pressure which causes sinus headaches.
  • Antihistamines: Histamines are natural chemicals in your body responsible for your body’s response to allergens. Antihistamines help block these chemicals to reduce allergy symptoms. Both OTC and prescription antihistamines are available.
  • Intranasal Corticosteroids: These medications are extremely effective at treating allergic rhinitis and help reduce sneezing, itching, nasal congestion, and runny nose.
  • Immunotherapy (allergy shots): If you don’t respond well to medications or experience side effects, allergy shots may be recommended by your allergist for a more permanent solution to an allergy problem.

If you’re experiencing sinus headaches and pain due to allergies, speak with your allergist for treatment options. Contact the professionals at the Allergy & Asthma Specialists of North Florida to schedule an appointment today.

how to keep allergic reactions under control

Understand Your Allergic Reactions and How to Keep them Under Control

Nearly 50 million people in the U.S. suffer from an allergic disease, according to the American Academy of Allergy, Asthma & Immunology (AAAAI). While the immune system is useful in defending the body against viruses and bacteria, the immune system may defend itself against substances that shouldn’t pose a threat to humans. These substances are referred to as allergens and your body’s defense is an allergic reaction.

What Causes an Allergic Reaction?

Why some people experience allergies is a mystery. Allergies may run in families and can be inherited. If a member of your family has allergies, you may be more likely to develop allergies.

The cause of the reaction can be traced to common substances. People with allergies are typically allergic to:

  • Bee stings (or other insect bites)
  • Foods (nuts, shellfish, etc.)
  • Medications (aspirin, penicillin, etc.)
  • Mold
  • Pet dander
  • Pollen

What Are Common Symptoms of an Allergic Reaction?

Depending on the substance you are allergic to, symptoms can affect your skin, digestive system, airways, sinuses, and nasal passages. These reactions can range from mild to severe and can trigger anaphylaxis, a life-threatening reaction.

Mild allergic reaction symptoms

  • Itching
  • Hives
  • Nasal congestion
  • Rash
  • Scratchy throat
  • Watery eyes

Severe allergic reaction symptoms

Severe reactions can cause anaphylaxis, a life-threatening reaction, resulting in a sudden drop in blood pressure, swelling of the airway, and difficulty breathing. If you experience a severe reaction, seek emergency assistance right away.

Additional severe symptoms include:

  • Flushing of the face
  • Fear/anxiety
  • Diarrhea
  • Difficulty breathing
  • Difficulty swallowing
  • Dizziness
  • Heart palpitations
  • Nausea or vomiting
  • Pain or tightness in chest
  • Swelling of face, eyes, or tongue
  • Unconsciousness
  • Weakness
  • Wheezing

How Are Allergies Diagnosed?

Your doctor or allergist can diagnose if you are allergic to foods or other environmental substances through exams and asking about your health history. Your doctor may perform one of the following three tests to determine your allergy.

Allergy Skin Testing

With an allergy skin test, your allergist will apply a trace of a suspected allergen on your skin and wait for a reaction. The substance may be applied by a small prick to the skin, injected under the skin, or taped to the surface of the skin. If you are allergic to one of the tests, you may experience redness and swelling at the test spot within 20 minutes. Delayed reactions may take several hours and typically disappear within 24 to 48 hours.

Skin tests are useful in diagnosing food and environmental allergens, including:

  • Allergic contact dermatitis (rash)
  • Bee sting or insect allergy
  • Food allergy
  • Penicillin allergy
  • Mold, pollen, or pet dander allergy

Allergy Elimination (or Challenge) Testing

To find out if you are allergic to a certain food, your doctor may suggest removing the food from your diet for several weeks. As you add the food back into your diet, you will be instructed to watch if any symptoms occur.

Allergy Blood Tests

If skin tests are not possible, your allergist may suggest a blood test to look for substances in the blood called antibodies. The most common test measures the blood level of an antibody, immunoglobulin E (IgE), which the body may make in response to an allergen. IgE levels are often higher in people with asthma or allergies.

7 Tips for Controlling an Allergic Reaction

Most people don’t know they have an allergy until symptoms occur. If you experience symptoms of an allergic reaction, here’s how you can help control them:

  1. If a severe reaction causes anaphylaxis, seek emergency medical help immediately. An epinephrine auto-injector (adrenaline) may be needed to manage the reaction right away.
  2. If an allergen causes a skin reaction such as a rash, wash the area thoroughly with mild soap and apply topical creams or medications to control the itching.
  3. Seasonal allergies can be treated with antihistamines and decongestants to reduce symptoms. Talk to your allergist about allergy shots to reduces reactions to seasonal allergies over time.
  4. Food allergy symptoms such as hives or itching can be treated with over-the-counter drugs. Prescription drugs are needed to treat other symptoms. Severe food allergies may be treated with epinephrine.
  5. Plant allergies causing redness, itching, swelling, and blisters can spread by touch. Thoroughly cleanse the area with soap and water for 10 minutes and take a cool bath. Apply anti-itching (calamine) lotion three to four times a day. See your doctor if symptoms get worse.
  6. If you experience an insect string, carefully removing the stinger in a swiping motion and wash the area with soap, water, and apply an antiseptic. Apply calamine lotion or hydrocortisone cream and cover the area with a bandage. An antihistamine can reduce itching, swelling, and hives.
  7. Drug allergies can be treated with an alternative prescription provided by your doctor. Epinephrine, antihistamines, and corticosteroids may be needed for serious drug allergy reactions.

See an Allergist for Diagnosis and Treatment

Allergies can develop at any age. If you experience symptoms of a severe allergic reaction, seek emergency medical help immediately. Schedule an appointment with an allergist to determine the cause(s) of an allergic reaction and to create a treatment plan.

5 Factors That Increase Your Chances of Having an Asthma Attack

Asthma is a serious condition affecting your airways. During an asthma attack, your airways may narrow, swell, and produce extra mucus making it difficult to breathe. This can trigger coughing, wheezing, and shortness of breath.

Did you know certain factors can increase your chances of having an asthma attack? While asthma can’t be cured, the symptoms can be controlled. The following five factors could increase your risk for asthma.

1. Having Another Allergic Condition

If you suffer from an allergic condition, such as eczema (atopic dermatitis) or hay fever, you may be more likely to experience asthma attacks. While allergies and asthma are two separate diagnoses, they share a strong genetic bond and often occur together.

Substances that trigger allergic reactions such as pollen, pet dander, and dust mites, may also cause asthma symptoms. For some people, food allergies could lead to an asthma attack. When asthma is triggered by allergic exposures, it is often referred to as allergic asthma or allergy-induced asthma.

2. Having a Relative with Asthma

Asthma often runs in the family. While family history is often overlooked, asthma can be caused by genes you inherit from your parents and interactions with the environment.

It’s important to talk to your relatives and get to know your family history, including if asthma was present. While you can’t change the past, you can tell your allergist about your family history of asthma, allergies, and common triggers. Knowing this information can help with your treatment.

3. Being Overweight

Having extra weight on your body is linked to worsening asthma symptoms. Even five extra pounds can worsen asthma control and a patient’s quality of life. In a Respiratory Medicine journal study, those who gained five pounds were associated with:

  • 22% poorer self-rated asthma control
  • 18% poorer self-reported quality of life
  • 31% increase in the odds of requiring use of a steroid

Excess weight also affects the potency of your asthma medications which help control asthma symptoms. Obese patients may not respond to controller medications, such as inhaled steroids, in the same manner as non-overweight asthmatics.

4. Air Pollutants

If you are exposed to second-hand tobacco smoke, smoke from fire, dust, exhaust fumes, and other air pollutants, your chances of experiencing asthma attacks are greatly increased. High pollution levels are more common on summer days leading to an increase in asthma episodes and visits to the emergency room.

Airborne-irritants and particles trigger asthma attacks by irritating the lungs and airways. These irritations make it difficult for patients to breathe properly, leading to the need for asthma drugs and emergency treatment. Both short-term and long-term exposure can cause health problems such as reduced lung function and an increase in asthma attacks.

5. Occupational Asthma

If you have asthma and are a hairdresser, farmer, work in manufacturing, or exposed to fragrances or chemical odors, you may be exposed to hundreds of chemicals daily that could be increasing your risk of asthma attacks.

Occupational asthma is often caused by inhaling fumes, gases, dust or other harmful substances while you work. Symptoms are often worse on the days and nights you work and may improve during time off.

You don’t have to suffer alone with asthma. By identifying the triggers and developing a treatment plan with your allergist, you can experience relief. Call the Allergy & Asthma Specialists of North Florida today to schedule an appointment to get your asthma symptoms under control.

asthma and allergies in jacksonville fl — how are they connected?

Understanding the Connection Between Asthma and Allergies

Asthma is a serious respiratory condition leading to difficulty breathing, coughing and wheezing. Allergies refer to a variety of hypersensitivity disorders causing a range of reactions. While asthma and allergies have two different definitions, they share a strong bond and often occur together.

Substances that trigger allergic reactions such as pollen, pet dander, and dust mites, may also cause asthma symptoms. For some people, food allergies can lead to asthma symptoms. These reactions are often referred to as allergic asthma or allergy-induced asthma.

Living a healthy, full life with allergies and/or asthma is very possible but may involve medical treatments and preventive measures.

Why does an allergic reaction cause asthma symptoms?

Your body creates an allergic response when the proteins of your immune system, called antibodies, identify a harmless substance as a high-risk invader. These antibodies adhere to the allergen as your body’s defense to protect itself. Chemicals released internally lead to itchy eyes, runny nose, nasal congestion, and skin reactions. For some people, these reactions can cause sudden asthma symptoms which affect the lungs and airways, and make it difficult to breath.

Do allergies always cause asthma?

No. While allergic asthma is common, asthma can be caused by several triggers including viral colds, tobacco smoke, stress, exercise, chemicals, solvents, pollution or gastroesophageal reflux (GER). Many people diagnosed with asthma have more than one type of asthma trigger.

Are allergies and asthma treated the same?

In general, allergies and asthma have different treatments. However, a few important treatments help both conditions are are listed below:

Allergen Immunotherapy (allergy shots): Immunotherapy is a powerful treatment for asthma and allergies that normalizes the immune system’s response to allergic triggers. Allergy shots contain tiny amounts of natural allergens and are administered in a regular fashion just below the skin surface. Over that time the therapy helps the immune system develop tolerance to those allergens. Both allergic reactions and asthma symptoms typically decrease during the treatment course.

Anti-Immunoglobulin E (IgE) Therapy: IgE is the type of allergic antibody your body releases when it mistakenly identifies a substance as harmful. Omalizumab (Xolair) helps interfere with your body’s IgE antibodies to prevent allergic reactions and asthma symptoms.

Leukotriene Modifier: Montelukast (Singulair) is a leukotriene modifier in a daily pill to help control immune system chemicals released by your body during an allergic reaction.

How do you keep allergic asthma under control?

Work with your allergist to decide if allergy medications or therapies would help your situation and prevent asthma attacks. You can also take these steps to help control your reactions:

  1. Avoid triggers. When you know what you’re allergic to, you can take steps to prevent exposure. To keep your home allergen free:
    • Keep food in the kitchen to avoid attracting pests throughout the house.
    • Wash your bedding in hot water each week.
    • Use mattress and pillow covers to guard against dust mites.
    • Vacuum daily with a HEPA-filter vacuum.
    • To reduce pet dander, limit areas in your home where pets can be such as the bedroom.
  2. Partner with your allergy specialist. Your allergist may recommend short-term or long-term medications for current relief and to get your asthma under control.
  3. Be prepared. You may be prescribed medications for allergies to reduce asthma triggers, but you should also carry a rescue inhaler in the event you’re exposed to unexpected allergies. Speak with your allergist to determine what’s best for you based on your triggers.

At the Allergy & Asthma Specialists of North Florida, we specialize in helping our patients identify allergy triggers and develop a treatment plan to decrease and eliminate allergic asthma reactions. Contact us to schedule an appointment and improve your quality of life by putting your allergies and asthma in the past.  

pollen allergies in jacksonville

10 Tips For Dealing With Pollen Allergies in Jacksonville

One of the more common allergy and asthma problems we see in North Florida are our patients’ responses to pollen. Pollen is a potent allergen that consists of microscopic, grains that are released by plants, then are carried to other plants by wind as part of nature’s pollination process. When pollen is being dispersed, it can be easily inhaled into sensitive nasal passages and trigger an allergic response. When you are allergic to pollen, your body sees it as an invader and mounts a defense that can result in watering eyes, constricted airways and a runny, itchy nose.

Here in Florida, pollen can be very difficult to avoid since each type of pollen in our area is released at different times. Our pollen seasons tend to begin earlier and last longer than those in other states and can be a year-round problem. Typically, Florida’s pollen seasons are December to May for tree pollen, April to November for grass pollen and July to November for weed pollen.

While we can’t control the seasons or the amount of pollen in the air, there are some things we can do to limit the extent of our exposure and our response to it.

Pollen Allergies in Jacksonville: Top 10 Tips to Control Them

Keep Windows at Home and in Cars Closed

When you’re experiencing allergy symptoms during pollen seasons, it’s best to keep your house and car windows shut at all times. While we have some beautiful weather here in Jacksonville, opening windows allows the pollen to get into your car or home and settle on every surface. Once pollen has accumulated on surfaces, even cleaning them can increase the possibility of an allergic reaction.

Use “Recirculation” with your Car’s AC

When you’re riding in the car, keep the air conditioning on the “recirculation” mode. This works to keep the already-filtered air circulating in the car. If the air conditioner is not needed, close all the vents. The vents still allow air flow when the air conditioning is off, so closing them will limit the pollen that makes it into the interior of your car.

Keep Air Conditioning Units Serviced and Clean

While there is no solid evidence that cleaning your air conditioning ducts can help you control your allergies, it is still a good idea to take the precaution of having your air conditioning units cleaned and serviced by an air conditioning company in Jacksonville before allergy season sets in. It is also a good idea to have your air conditioner set to recycle the air in your home (similar to the recirculation setting in your car). Getting your air conditioning serviced and your filters replaced with a HEPA filter can also reduce the amount of allergens in the air around you.

Pay Attention to How Much Pollen You Bring in your House

Limit how much pollen you are tracking into your home, especially into your bedroom. When you come in from the outdoors, take a shower immediately and change clothes. For women especially, hair traps a good amount of pollen, so it’s important to wash your hair before bed each night.

Limit Your Time Outdoors in the Early Mornings

Pollen counts in Jacksonville tend to be highest in the mornings, typically between 5:00 a.m. and 10:00 a.m. Limit your exposure by avoiding outdoors when pollen counts are highest. If you’re an outdoor enthusiast, try to schedule your outings for the afternoons instead of the mornings. If you suffer from severe pollen allergies, you might consider engaging in indoor sporting activities only during the peak of pollen season.

Avoid Tackling Lawn and Outdoor Work

Lawn mowing will stir up settled pollens, so mowing duties should be left to family members who aren’t allergic to pollen if at all possible. Wear a protective mask and eye protection while doing yard work during your pollen season. If that’s not an option, consider hiring a local lawn care and control company.

Look Out for the Pollen on Your Pets

House pets that spend time outdoors will bring pollen indoors on their fur. Be sure to wash your pets at least one or two times per week during your peak allergy season. Always keep your pets off your bed and preferably out of your bedroom altogether.

Keep Bedroom Linens Clean

Wash bed linens at least once per week to get rid of any pollen that may have settled there. When doing laundry, avoid using an outdoor clothesline during the pollen seasons.

Carpets are Pollen Traps: Keep them Clean

Keep carpets vacuumed and clean. Vacuuming will remove pollen and other allergens (like pet dander) that have settled in your carpets. It would also be a good idea to steam clean your carpets at the beginning of the allergy season. Either do it yourself or have a professional Jacksonville carpet cleaning company do it for you.

Be proactive and aware!

Check the pollen reports during allergy season. This will help you prepare for your day and know what to expect. For convenience, the Jacksonville area pollen forecast is regularly posted on our website at www.JaxAllergy.com.

Allergic reactions to pollen can be a frustrating and annoying part of your life, but following these tips can help limit your immune system’s response. If you believe your symptoms are worse than normal or you aren’t sure what’s causing your reactions, contact us to schedule an appointment with one of our board-certified Jacksonville Allergy Specialists.

oral allergy syndrome

About Oral Allergy Syndrome: Symptoms & Treatments

Do you experience allergic symptoms in the mouth when eating certain raw foods? If you do, you could be suffering from oral allergy syndrome.

Oral allergy syndrome is actually fairly common for seasonal allergy sufferers. As people with seasonal allergies eat uncooked or raw fruits, vegetables, and some nuts, the immune system in their mouth can mistake certain proteins in the raw food as pollens and a local allergic reaction follows.

Learn more about oral allergy syndrome including the causes and how you can treat the symptoms.

What Is Oral Allergy Syndrome?

Oral allergy syndrome (OAS) is also known as pollen-food allergy syndrome. This is caused by cross-reacting allergenic proteins found in airborne pollens and raw vegetables, fruits, and tree nuts.

The immune system of individuals with seasonal allergies recognizes similar appearing proteins in raw foods as allergens, which causes a local allergic reaction inside the mouth.

Raw foods tend to cause the most allergic reactions. Often times, the allergy sufferers won’t experience an allergic reaction when the food is heated and cooked. This is because heating changes the molecular structure of the protein and renders it non-allergenic.

What Causes Oral Allergy Syndrome?

Not everyone with a pollen allergy will experience oral allergy syndrome. Common triggers for oral allergy syndrome include:

  • Grass Pollen – cross reacts with foods including peaches, oranges, melons, tomato, and celery
  • Birch Pollen – cross reacts to foods including peaches, pear, plum, kiwi, cherry, apple, hazelnut, almond, carrot, and celery
  • Ragweed Pollen – cross reacts with foods including melons, banana, cucumber, zucchini, and sunflower seeds

What Are Oral Allergy Syndrome Symptoms?

Oral allergy syndrome symptoms are typically experienced immediately after coming in contact with food. These uncomfortable allergic reactions can include:

  • Itchy mouth
  • Scratchy throat
  • Mild swelling of lips, mouth, tongue, and throat
  • Itchy ears (in some cases)

Most of these symptoms are concentrated in the mouth area and do not spread; however, there have been rare reports of more severe and systemic symptoms. Symptoms typically occur quickly as the fresh fruit or raw vegetable reaches the mouth. After swallowed or removed, the allergic symptoms may subside within minutes to one hour.

Most Common Oral Allergy Syndrome Culprits

How Do You Avoid It?

The best way to avoid oral allergy syndrome symptoms is by avoiding raw foods known to be problematic. Be aware of your pollen allergies and which foods are associated with certain pollen proteins.

An allergist can help diagnose which pollens and foods cause allergic reactions by reviewing your clinical history, conducting skin pricks, and performing oral food tests with raw fruit and vegetables.

By educating yourself about the foods causing the problem, you can avoid the reaction from taking place.

What are Your Options for Oral Allergy Syndrome Treatment?

Though symptoms may subside in a few minutes or within the hour, don’t ignore allergic symptoms when they occur. Stop eating foods which cause an allergic reaction and take an antihistamine to relieve itchiness.

Consult with your allergist when you or your child experience oral allergy syndrome symptoms. Symptoms may occur in children as young as 3 or 4 or begin later in life for adults. An allergist can conduct tests to pinpoint which foods are causing allergic reactions and whether it’s oral allergy syndrome or another kind of food intolerance.

What You Should Know About Stinging Insect Allergy This Summer

While stinging insects may be a minor annoyance to some, for others they can lead to serious, life-threatening allergic reactions. Thousands enter emergency rooms each year and potentially life-threatening allergic reactions occur in 0.4%-0.8% of children and 3% of adults. Anaphylaxis resulting from insect stings claims at least 90-100 lives each year.

Learn more about insect sting allergy, including symptoms, treatment, and how to prevent getting stung.

What Are Common Symptoms of Insect Sting Allergy?

Insect stings can cause one or more of the following symptoms:

  • Redness
  • Swelling (near the sting and beyond)
  • Pain
  • Itching
  • Hives

Serious allergic reactions require immediate medical attention. Symptoms of a potentially severe allergic reaction to an insect sting may include:

  • Hives, itching, and swelling beyond the site of the sting
  • Intense nausea or diarrhea, vomiting, and abdominal cramping
  • Swelling of the tongue or throat and difficulty swallowing
  • Anaphylaxis, a potentially life-threatening reaction that impairs breathing and causes the body to go into shock

Severe reactions can occur within minutes after a sting. Those who experience an allergic reaction to an insect sting have a 60% chance of a similar or worse reaction if they are stung again.

How Is Insect Allergy Diagnosed?

If you’re concerned about having an insect sting allergy, your allergist can diagnose the allergy and offer a treatment plan.

An allergist can test for the following five insects:

  • Fire ant
  • Honey bee
  • White-faced hornet and yellow-faced hornet
  • Yellow jacket
  • Paper wasp

After reviewing your medical history, an allergist will ask questions about previous insect stings, any reactions to stings, and what additional symptoms you experienced. A skin-prick test or a blood test can help diagnosis an allergy.

How Do You Manage & Treat Insect Allergy?

There is a two-step approach for managing and treating insect allergy:

  1. As soon as a reaction occurs, seek medical attention immediately.
  2. Preventive treatments can help prevent future allergic reactions.

Medical Attention

Don’t delay when a reaction occurs. Medical attention may include epinephrine, antihistamines, and in some cases, oxygen, intravenous fluids, and corticosteroids. If you have a known history of insect allergy, injectable epinephrine should be carried with you and call 911 if epinephrine is used.

Preventive Treatments

Venom immunotherapy is a highly effective therapy administered by an allergist that helps to retrain your immune system to become tolerant to insect venoms and thereby prevent future life-threatening reactions to insect stings. This is accomplished by gradually administering very small doses of the culprit insect venom to decrease sensitivity to the venom. While there is no cure for allergies to insect venoms, immunotherapy is the closest thing to it because it substantially decreases the likelihood that a life-threatening allergic reaction will occur to future insect stings.

How Can I Prevent Insect Stings?

The best way to prevent stings is to avoid bees, fire ants, wasps, hornets, and yellow jackets during the summer. Try not to look or smell like a flower when spending time outdoors. Some experts think khaki and gray colored fabrics and abstaining from perfumes or other scented personal use items will help you avoid getting stung.  Always use caution around areas where yellow jacket nests are in the ground or hornet and wasp nest found in trees, bushes, or on buildings.

In addition, use the following precautions:

  • Avoid being barefoot in the grass
  • Do not leave open beverage cans unattended
  • Keep food covered outdoors
  • Seal garbage cans

Vitamin D Deficiency and Food Allergies: Does One Relate to the Other?

Food allergies are becoming an epidemic in today’s societies with a noticeable increase in cases in just the last decade. In the U.S. and Australia alone, 10% of infants 12 months old have been clinically diagnosed with a food allergy.

Just as food allergies increased, levels of vitamin D decreased. It’s estimated that 50% of the population in Western countries lack sufficient levels of vitamin D with 10% of the population are deficient in vitamin D.

This makes researchers wonder, could there be a correlation between food allergies and vitamin D?

Benefits of Vitamin D[1]

Vitamin D is often known as the “sunshine vitamin” because it is absorbed by the skin. It is also absorbed by eating certain foods or taking supplements.

Oily fish including salmon, sardines, and tuna have the richest sources of vitamin D. Other good sources include egg yolks, liver, and foods specially fortified with vitamin D.

Vitamin D is an essential nutrient to support healthy body functions. Sufficient levels of vitamin D helps:

  • Regulate calcium and phosphorus absorption to support healthy bones and teeth
  • Protect against diseases such as type 1 diabetes, hypertension, cancer, and multiple sclerosis
  • Support brain health, the nervous system, and the immune system
  • Aid in cardiovascular health and lung function

Symptoms of Vitamin D Deficiency[2]

How do you know if you are vitamin D deficient? Many people don’t develop symptoms until their levels are low for a while. This can make vitamin D deficiencies hard to diagnose.

Common symptoms include:

  • Bone pain
  • Frequent bone fractures
  • Muscle weakness
  • Difficulty forming clear thoughts
  • Depression

Low levels of vitamin D can lead to more severe health issues such as:

  • Cardiovascular disease
  • Cancer
  • Cognitive impairment in older adults
  • Asthma in children

Can Vitamin D Affect Food Allergies?  What the Research Says

Studies show locations further away from the equator (areas lacking ultraviolet radiation (UVA)) have higher rates of child food allergy-related hospital visits, peanut allergies, and epinephrine prescriptions. In addition, being born in the fall or winter with less UVA exposure relates to higher risks of food allergies and anaphylaxis in children.

Diet can also be a contributing factor. An Australian study found that children who were introduced to eggs after six months of age had a higher risk for food allergy than infants who were introduced to eggs when they were 4-6 months.

What This Means for You

The research comparing vitamin D deficiencies to food allergies is not conclusive and more research is needed to know if vitamin D can reverse food allergies. What we do know is vitamin D can protect against food allergies and is critical for your overall health and well-being.

If you think you may be vitamin D deficient, your doctor can assess your levels by a simple blood test and recommend supplements. Only take supplements under the care of health care professionals such as your primary care physician or allergist.
