Understanding Exercise-Induced Urticaria: Causes, Symptoms, and Treatment
Have you ever experienced an abrupt onset of hives while exercising or doing any physical activity? This spontaneous reaction may be due to a condition called Exercise-Induced Urticaria (EIU).
EIU is a rare condition that affects people of all ages and fitness levels. It occurs due to histamine release in the skin as a response to exercise and can sometimes be life-threatening. If you’re experiencing hives while exercising, this article will help you understand the causes, symptoms, and treatment options for EIU.
Causes of Exercise-Induced Urticaria
The exact cause of EIU is unknown; however, it is thought to be due to a rise in body temperature during exercise, leading to histamine release in the skin. This response triggers the formation of hives, which can be itchy and painful.
Additionally, certain conditions or triggers can increase the incidence of EIU. These include, but not limited to, environmental factors, certain food, medications, and underlying medical conditions.
Symptoms of Exercise-Induced Urticaria
The most apparent symptom of EIU is the abrupt onset of hives on the skin, typically within 15-30 minutes of physical activity. Symptoms can range in severity from mild to severe.
In severe cases, the affected person can experience anaphylaxis, a life-threatening medical emergency, which can cause breathing difficulties, loss of consciousness, and low blood pressure.
If hives occur during or after exercise, they may be accompanied by symptoms such as itching, swelling, and redness of the skin.
Treatment Options for Exercise-Induced Urticaria
There are several treatment options available for managing EIU, which includes medications, lifestyle modifications, and avoiding triggers.
Antihistamines such as cetirizine, loratadine, and fexofenadine are often prescribed to relieve symptoms associated with EIU.
In severe cases, epinephrine auto-injectors are administered to prevent anaphylaxis. Lifestyle modifications such as wearing breathable clothing, avoiding exercise in hot and humid conditions, and drinking plenty of fluids are essential measures to reduce the incidence of EIU.
In conclusion, EIU is a rare condition that affects people of all ages and fitness levels. The exact cause of EIU is not known, but the onset of hives is due to histamine release in the skin during exercise. Symptoms can range from mild to severe, with the potential for life-threatening anaphylaxis in some cases.
There are various treatment options available for managing EIU, ranging from medications, lifestyle modifications, and trigger avoidance. If you experience hives or other symptoms during exercise, talk to your doctor, who can help guide you on the best course of action.
