Excessive Sweating
Sweating is a physiological event that occurs to regulate the body's temperature. Excessive sweating (hyperhidrosis) is a condition characterized by an unusually high amount of sweating independent of environmental conditions and the body's temperature control. Patients with hyperhidrosis do not need to exert themselves to experience sweating; in fact, they may experience dripping sweat from their hands even while sitting. The condition can develop as a primary disorder, as a side effect of medication, or due to a medical condition. Regional excessive sweating, especially in the armpits, palms, soles of the feet, and less commonly in the head and neck region, is known as localized hyperhidrosis.
Sweating while eating can occur in a condition known as Frey syndrome. Generalized hyperhidrosis can occur due to hormonal, neurological, or infectious causes, as well as conditions such as cardiovascular diseases, respiratory system diseases, medication side effects, and poisoning.
Localized excessive sweating is more common than other sweating disorders. While the exact cause is not fully understood, it is often attributed to the inappropriate functioning of the nervous system as the underlying cause of the condition.
