Cholinergic urticaria is actually quite common from the forms of chronic urticaria. Cholinergic Urticaria is a form of what are more commonly referred to as hives that are typically brought on by sweating due to sensitivity to one’s own sweat or other physical stimuli.
Cholinergic Urticaria is identifiable by the presence of areas that appear “broken out” with small bumps, similar to what is commonly called “goose bumps.” It may appear as an itching, burning sensation followed by or accompanied with the raised, red bumps.
Where do you get cholinergic urticaria?
It may occur anywhere on the body but most often occurs on the torso and arms. In more severe cases, the bumps may combine to form larger areas of swelling. Along the skin outbreak, some affected may also experience headaches, palpitations, and shortness of breath, salivation, fainting, abdominal cramps or diarrhea. In very rare cases sufferers may experience anaphylaxis. Persons with this symptom should not exercise alone as this can be fatal.
What causes cholinergic urticaria?
While emotional stress is considered a factor, it is also known as exercise-induced times because of the activities aggravated the problem.
An outbreak is typically triggered by high heat/humidity, heavy exercise producing sweating, excessively spicy foods, and stress, but will typically subside within an hour or two. In some cases the bumps may be accompanied by or progress to cutaneous inflammation (wheals) and pain.
The condition may occur across all demographics in approximately 5%-20% of the population but seems more prevalent in young adults, specifically in the 26-28 year old age group. Most cases are mild and go unreported and untreated.
How do you treat cholinergic urticaria?
Treatment often involves merely refraining from the causation factors as discussed. But for instances when this is not a feasible alternative, it may then become be necessary to use antihistamines, whether simply over the counter or prescribed by your physician depending on the severity of the reaction. Your physician will elevate histamine levels by exercise or sessions on a treadmill to produce generalized and warms. This will help determine what responses are accentuated in response to physical stimuli that result in an outbreak.
Effective antihistamines used are Loratadine and Desloratadine, Cetirizine, Danazol. Some Beta blockers, such as propranolol, have also been found to be somewhat useful in the treatment of the condition. Many topical ointments such as benzoyl scopolamine can also be beneficial in reduction of symptoms short term.
