The condition develops due to the release of chemical substances, such as histamines, platelet activating factor, and cytokines (example bradykinin), from inflammatory cells called mast cells and basophils.

Cholinergic urticaria is due to an increase in body temperature because of sweating, exercise, hot showers and/or anxiety.

If no inducible factor is present, the process is termed chronic spontaneous urticaria (CSU). Urticaria is often caused by the sting of the nettle and certain other plants. Insect bites, temperature, and chemical agents are also among its causes.
