Sweat Allergy
Sweat allergy, also known as Cholinergic Urticaria, is a type of physical urticaria where hives or 'wheals', are produced by the body in response to the body's own sweat. This condition is relatively rare and can cause significant discomfort and distress to those affected.
Symptoms[edit]
The symptoms of sweat allergy can vary from person to person, but typically include:
- Itching or pruritus
- Redness or erythema
- Small, raised bumps or hives
- A burning sensation
- Difficulty in breathing in severe cases
These symptoms can be triggered by any activity that causes the body to sweat, such as exercise, heat, emotional stress, or spicy foods.
Causes[edit]
The exact cause of sweat allergy is unknown, but it is thought to be an autoimmune response where the body's immune system mistakenly identifies its own sweat as a harmful substance and reacts against it. This results in the release of histamine and other chemicals, leading to the symptoms of the condition.
Diagnosis[edit]
Diagnosis of sweat allergy can be challenging, as the symptoms can be similar to other skin conditions. A detailed medical history and physical examination are usually the first steps. A skin prick test or intradermal test may be performed to confirm the diagnosis.
Treatment[edit]
Treatment for sweat allergy typically involves avoiding triggers that cause sweating, and managing symptoms when they occur. This can include:
- Antihistamines to reduce itching and hives
- Corticosteroids to reduce inflammation
- Immunotherapy in severe cases
