What condition is characterized by excessive sweating, often due to heat?

Hyperhidrosis is defined as a condition where an individual experiences excessive sweating that is not necessarily related to heat or exercise. This can occur in localized areas, such as the palms, feet, or underarms, or it can be generalized across the body. The primary factor contributing to hyperhidrosis is often overactivity of the sweat glands, which can be influenced by various factors including genetics, hormonal changes, and certain medical conditions.

Understanding hyperhidrosis is crucial since it can impact one’s quality of life, leading to social embarrassment or anxiety. Treatment options can include antiperspirants, medications, or procedures such as Botox injections to reduce the activity of the sweat glands.

The other options refer to different conditions that do not specifically involve excessive sweating due to heat. Acanthosis nigricans is characterized by dark, velvety patches of skin often associated with insulin resistance, hirsutism pertains to excessive hair growth in women in areas typically seen in men, and pruritus refers to itching, not sweating. Each of these conditions has distinct causes and symptoms, highlighting the importance of correctly identifying hyperhidrosis in the context of sweating disorders.
