Heat urticaria

Heat urticaria refers to the situation where urticaria patients will show symptoms such as itching, redness and swelling when they encounter heat, and the complications will not occur when the temperature drops. Patients need to pay attention to changes in the temperature of the environment in which they live, and then take medication according to the doctor's advice. Heat urticaria can cause papular wheals and a burning sensation in patients. As long as the patient lowers his body temperature, the symptoms will disappear automatically.

Heat urticaria is also called cholestatic urticaria or acetylcholine urticaria. As the name suggests, heat urticaria occurs when the human body is exposed to heat. In daily life, exercise, mental excitement, drinking hot drinks, drinking alcohol, etc. will cause the temperature deep in the body to rise. At this time, acetylcholine will act on mast cells, leading to the occurrence of heat urticaria.

Symptoms of heat urticaria

Heat urticaria is similar to common urticaria. When the disease occurs, papular wheals with redness will appear on the body. These wheals may cause intense itching or burning. The difference between heat urticaria and general urticaria is that when the patient calms down and stops exercising, the urticaria will subside, so the symptoms are not very serious. However, heat urticaria may also cause systemic symptoms such as headache, diarrhea, and dizziness.

Do not drink hot drinks and alcoholic beverages. Patients with heat urticaria can let hot drinks cool to room temperature before drinking them, but try not to drink alcoholic beverages. 4. Keep a calm mood. Excitement and tension can trigger this disease.
