Which condition is characterized by excessive and profuse perspiration?

The condition characterized by excessive and profuse perspiration is hyperhidrosis. This disorder causes the sweat glands to be overactive, leading to an abnormally high production of sweat that can occur even in the absence of heat or physical exertion. It can affect various parts of the body, including the hands, feet, underarms, and face, and it may significantly impact a person’s quality of life due to discomfort and social embarrassment.

In contrast, dermatitis refers to inflammation of the skin with symptoms like itching, redness, and swelling but does not involve excessive sweating. Anhidrosis is the inability to sweat normally, which can result in overheating and does not align with the idea of profuse perspiration. Osmidrosis relates to an unpleasant body odor that can arise from perspiration but, again, does not denote an excess in sweat production itself. Therefore, hyperhidrosis is the distinct condition of excessive sweating, distinguishing it from the other terms.
