Exercise-induced anaphylaxis is a rare condition that can cause serious symptoms. This article explains what it is, its causes, and what you can do to manage it.
Introduction:
Have you ever experienced hives, itching, or difficulty breathing during or after exercise? If so, you may have exercise-induced anaphylaxis (EIA). EIA is a rare condition that affects people of all ages and fitness levels. In this article, we’ll explore what EIA is, what causes it, and how you can manage it.
What is Exercise-Induced Anaphylaxis?
Exercise-induced anaphylaxis is a type of anaphylaxis that occurs during or after physical activity. Anaphylaxis is a severe allergic reaction that can be life-threatening if not treated promptly. EIA is different from other types of anaphylaxis because it is triggered by exercise.
What Causes Exercise-Induced Anaphylaxis?
The exact cause of EIA is unknown, but researchers believe that it may be related to changes in the body during exercise. Some theories suggest that EIA may be caused by:
- Increased blood flow to the skin, which can lead to hives and itching
- Increased permeability of blood vessels, which allows allergens to enter the bloodstream more easily
- Release of histamine and other chemicals in response to exercise
Who is at Risk for Exercise-Induced Anaphylaxis?
Anyone can develop EIA, but it is more common in people who have a history of allergies or asthma. Women are also more likely to develop EIA than men.
Symptoms of Exercise-Induced Anaphylaxis
The symptoms of EIA can vary from person to person and may range from mild to severe. Some common symptoms include:
- Hives or welts
- Itching or flushing of the skin
- Swelling of the face, lips, tongue, or throat
- Abdominal cramping or pain
- Nausea or vomiting
- Difficulty breathing or wheezing
- Dizziness or lightheadedness
- Loss of consciousness
If you experience any of these symptoms during or after exercise, seek medical attention immediately.
Managing Exercise-Induced Anaphylaxis
If you have been diagnosed with EIA, your doctor may recommend that you carry an epinephrine auto-injector (EpiPen) with you at all times. An EpiPen is a self-administered injection that can help stop the symptoms of anaphylaxis.
In addition to carrying an EpiPen, there are several other steps you can take to manage EIA, including:
- Avoiding exercise or activities that trigger your symptoms
- Exercising in cooler temperatures or in a swimming pool
- Taking antihistamines before exercising
- Wearing loose-fitting clothing during exercise
- Drinking plenty of fluids before, during, and after exercise

How to prevent exercise-induced anaphylaxis?
There is no surefire way to prevent exercise-induced anaphylaxis (EIA), but there are several steps you can take to reduce your risk of experiencing an allergic reaction during exercise. Here are some tips:
- Avoid known triggers: If you have a history of EIA or other allergies, try to avoid triggers that you know can cause a reaction. This might include certain foods, medications, or environmental allergens.
- Take antihistamines: Your doctor may recommend taking an antihistamine before exercising to help prevent symptoms of EIA. Antihistamines can help reduce inflammation and prevent the release of histamine and other chemicals that can cause an allergic reaction.
- Exercise in cooler temperatures: Exercise-induced anaphylaxis is more common in hot, humid conditions. Try to exercise in cooler temperatures or indoors, where the air is cooler and drier.
- Stay hydrated: Drinking plenty of fluids before, during, and after exercise can help keep your body hydrated and reduce the risk of EIA.
- Wear loose-fitting clothing: Tight clothing can cause heat to build up, increasing the risk of an allergic reaction. Wear loose, comfortable clothing that allows your skin to breathe.
- Carry an epinephrine auto-injector (EpiPen): If you have been diagnosed with EIA, your doctor may recommend that you carry an EpiPen with you at all times. An EpiPen is a self-administered injection that can help stop the symptoms of anaphylaxis.
Remember, if you experience symptoms of EIA during or after exercise, seek medical attention immediately. With proper management and treatment, most people with EIA can continue to lead active, healthy lives.
Exercise-induced anaphylaxis can be prevented by avoiding certain food triggers that can cause an allergic reaction during exercise[1][2]. Common food triggers include alcohol, apples, beef, eggs, fish, legumes, milk, mushrooms, nuts, peaches, pork, shellfish, soy, tomatoes, and wheat/wheat protein[1]. Antihistamines may also be partially effective in preventing exercise-induced anaphylaxis[3]. If you have a history of exercise-induced anaphylaxis, it is important to talk to your doctor about how to prevent future episodes and what to do in case of an emergency[4][5].
