Exercise-Induced Urticaria

Exercise-induced urticaria (EIU) is a condition where hives or welts develop on the skin during or after physical activity. These hives can be itchy, red, and swollen, causing discomfort. In this article, we’ll break down everything you need to know about EIU in simple, easy-to-understand language.

Types of Exercise-Induced Urticaria:

1. Cholinergic Urticaria: This type is triggered by an increase in body temperature due to activities like jogging, hot showers, or emotional stress.
2. Cold Urticaria: Cold weather or cold water exposure can cause hives in this type of EIU.

Common Causes of Exercise-Induced Urticaria:

1. Heat: Sweating and increased body temperature during exercise can lead to EIU.
2. Cold: Sudden exposure to cold air or water can trigger cold urticaria.
3. Pressure: Activities that put pressure on the skin, like weightlifting, may lead to hives.
4. Allergens: Some people may be allergic to substances found in gyms, like latex or cleaning chemicals.
5. Stress: Emotional stress can bring on cholinergic urticaria.
6. Medications: Certain medications can make you more susceptible to EIU.
7. Food: Consuming certain foods before exercise can cause hives in sensitive individuals.
8. Infections: Viral or bacterial infections can sometimes trigger EIU.
9. Underlying Health Conditions: Conditions like lupus or thyroid disorders can be associated with EIU.
10. Exercise Intensity: High-intensity workouts can be more likely to trigger EIU.
11. Dehydration: Not drinking enough water can increase the risk of developing hives during exercise.
12. Clothing: Wearing tight or rough-textured clothing can irritate the skin.
13. Foods High in Histamine: Some foods, like aged cheeses and certain alcoholic beverages, contain histamines that can worsen EIU.
14. Environmental Factors: Pollen, pollution, or other environmental factors can contribute to EIU.
15. Hormonal Changes: Hormonal fluctuations, such as those during menstruation, can affect EIU symptoms in some individuals.
16. Inadequate Warm-up: Skipping a proper warm-up before exercise can increase the risk of EIU.
17. Overexertion: Pushing yourself too hard during a workout can trigger hives.
18. Sweating: Excessive sweating can lead to EIU, especially in hot and humid conditions.
19. Alcohol Consumption: Alcohol can dilate blood vessels and make EIU worse for some people.
20. Genetics: Family history may play a role in developing EIU.

Common Symptoms of Exercise-Induced Urticaria:

1. Hives: Raised, itchy, red or white welts on the skin.
2. Itching: Intense itching, often around the hives.

10. Challenge with Medications: Suspected medication triggers can be tested under medical supervision.
11. Histamine Release Test: Measures histamine levels in the blood during exercise.
12. Thyroid Function Test: Checks for thyroid disorders as a potential cause.
13. Spirometry: Measures lung function if breathing difficulties are a concern.
14. Skin Biopsy: Rarely, a sample of skin tissue may be examined under a microscope.
15. Exercise Diary: Keeping a record of exercise activities and symptoms.
16. Provocation Tests: Gradually increasing exercise intensity to induce symptoms.
17. Food Challenge: Reintroducing foods after an elimination diet to identify triggers.
18. Environmental Allergy Testing: Identifies environmental allergens that may worsen EIU.
19. X-rays or Scans: If underlying conditions are suspected, imaging tests may be necessary.
20. Challenge with Cold Exposure: To diagnose cold urticaria, the skin is exposed to cold objects or water.

Treatments for Exercise-Induced Urticaria:

1. Avoidance: Identify and avoid triggers, like specific foods or exercise conditions.
2. Antihistamines: Over-the-counter or prescription antihistamines can reduce symptoms.
3. Epinephrine Autoinjector: In severe cases, carry an epinephrine injector for emergencies.

Exercise-induced urticaria is a condition where hives, which are itchy, red, and swollen welts on the skin, occur during or after physical activity. There are two main types of EIU: cholinergic urticaria, triggered by an increase in body temperature, and cold urticaria, triggered by exposure to cold.

Common causes of EIU include heat, cold, pressure, allergens, stress, medications, food, infections, underlying health conditions, exercise intensity, dehydration, clothing, histamine-rich foods, environmental factors, hormonal changes, inadequate warm-up, overexertion, sweating, alcohol consumption, and genetics.

Symptoms of EIU include hives, itching, swelling, burning, redness, warmth, flushing, pain, difficulty breathing, dizziness, increased heart rate, nausea, headache, fatigue, anxiety, joint pain, abdominal pain, sweating, runny nose, and hoarseness.

Diagnosis involves various tests such as physical examination, exercise challenge test, skin prick test, blood tests, allergen-specific IgE test, patch testing, history and symptom tracking, elimination diet, cold stimulation test, challenge with medications, histamine release test, thyroid function test, spirometry, skin biopsy, exercise diary, provocation tests, food challenge, environmental allergy testing, and X-rays or scans.

Treatment options for EIU include avoidance of triggers, antihistamines, epinephrine autoinjectors for emergencies, leukotriene inhibitors, corticosteroids, temperature regulation, relaxation techniques, hydration, non-sedating antihistamines, desensitization, allergen immunotherapy, skin protection, H2 antagonists, avoiding high histamine foods, pain relievers, topical creams, anti-inflammatory diet, moisturizers, and psychological support.

Common medications used to manage EIU include cetirizine, loratadine, fexofenadine, diphenhydramine, epinephrine, montelukast, prednisone, ranitidine, hydroxyzine, omalizumab, cromolyn sodium, ibuprofen, aspirin, methotrexate, tacrolimus, azathioprine, topical steroids, amitriptyline, nifedipine, desloratadine, and others.

In conclusion, understanding exercise-induced urticaria, its types, causes, symptoms, diagnosis, treatments, and medications is essential for managing this condition effectively and improving the quality of life for those affected.
