What skin condition is indicated by excess sweating?

Excess sweating is clinically defined as hyperhidrosis, a condition characterized by an overproduction of sweat by the sweat glands. This can occur in localized areas of the body, such as the palms, soles of the feet, or underarms, or it can be generalized, involving larger areas. Hyperhidrosis can be triggered by various factors, including hormonal changes, stress, heat, or certain medical conditions. Understanding hyperhidrosis is important for treatment purposes, as individuals affected may require specific management options to alleviate the discomfort or social issues caused by the condition.

The other options represent different skin conditions that do not involve excess sweating. Anhidrosis refers to the absence of sweating, which is the opposite of hyperhidrosis. Dermatitis is an inflammation of the skin and can be caused by various irritants or allergic reactions, while psoriasis is a chronic autoimmune condition that leads to the rapid growth of skin cells, resulting in thick, red patches covered with silvery scales. These conditions are distinct from hyperhidrosis, clearly emphasizing how hyperhidrosis directly relates to excessive sweating.
