Cholinergic Urticaria is a medical term used to describe a subcategory of physical urticaria (hives). It is characterized by a hypersensitive response in the skin as a result of the body increasing in temperature (passively or actively), or the precipitating release of sweat. Individuals with this physical heat hives condition often ask, ?Why do I itch when I get hot or exercise?? This is the most common symptom experienced by sufferers. Individuals may experience a cholinergic urticaria reaction in response to any activity that increases overall body temperature (or causes a sweat release). Some examples include the following: Taking a hot shower or bath Eating spicy foods Exercising or doing physical activities that increase body temperature Stress or anxiety Emotional responses (sadness, anxiety, anger, laughter) Transitioning from a cool environment to a hotter environment without allowing the body time to slowly acclimate to the temperature difference (such as walking from a cold room to a hot room). Cholinergic Urticaria Treatments There is no cure for Cholinergic urticaria, and treatment options are often limited. Some common treatments include taking antihistamines (such a Allegra, Zyrtec, or stronger ones), avoiding known triggers (such as hot weather, physical activity, and spicy foods), corticosteroids (only for extreme cases), anabolic steroids, UVB therapy, sweat/exercise therapy, diet changes (such as avoiding known trigger foods), and more.

Individuals may experience periods of heightened sensitivity, as well as periods of almost no reactions or very low sensitivity. This can sometimes be affected by seasonal weather, as well as other unknown factors. This condition may last for months, years, or may even go away and come back sporadically throughout one?s live. In one study, the average duration was approximately 7 years, although some people had this condition (on and off) for up to 30 years. Even though this condition may be long-lasting and highly variable, individuals suffering with this can often find treatment regimens that enable them to live a relatively high quality of life and go on to work, go to school, and engage in other activities. This is not considered a terminal disease, and it is not known to shorten life span, cause early death, or any other immediate dangers. The only exception is that in rare cases, people with a severe case of cholinergic urticaria may experience anaphylactic shock (severe swelling), which could be life threatening. This is very rare, and if this happens, please call a doctor or hospital immediately.
