Physical Urticaria, Cholinergic Type:

Definition and Description of Physical Urticaria, Cholinergic Type:

Physical Urticaria, Cholinergic Type, also known as cholinergic urticaria (CU), is a form of hives that occurs due to an allergic reaction triggered by an increase in body temperature. This increase can result from various factors, including exercise, hot showers, or emotional stress. CU is characterized by the rapid onset of small, itchy welts or bumps on the skin, often accompanied by flushing and sweating. The condition is typically self-limiting, although the frequency and severity of episodes can vary significantly among individuals.

Causes of Physical Urticaria, Cholinergic Type:

The exact causes of cholinergic urticaria are not fully understood, but it is believed to involve the release of histamine and other chemicals from mast cells in the skin in response to elevated body temperature. Underlying conditions such as hyperthyroidism, infections, or autoimmune disorders may contribute to the onset of CU. Genetic predispositions may also play a role, as the condition sometimes runs in families.

Associated Symptoms of Physical Urticaria, Cholinergic Type:

Common symptoms associated with cholinergic urticaria include:

Itchy, raised welts or hives
