Cholinergic Urticaria

Cholinergic urticaria is a skin condition that can cause itchy hives or welts when your body heats up or you experience emotional stress. In this article, we’ll provide plain English explanations of cholinergic urticaria, its types, causes, symptoms, diagnostic tests, treatment options, and drugs commonly used to manage it.

Cholinergic urticaria is a fancy way of saying that you get itchy hives when your body temperature rises, like when you’re hot or anxious. It happens because your body releases a substance called acetylcholine, which triggers your skin to break out in hives.

2. Localized Cholinergic Urticaria: In this type, hives are limited to specific areas, like the chest or arms, when triggered.
3. Exercise-Induced Urticaria: Exercise can cause hives in some people with this type, making it a bit tricky to stay active.
