What is the medical term for excessive sweating?

The term for excessive sweating is hyperhidrosis. This condition is characterized by an abnormal increase in sweat gland activity, leading to significant sweating that can occur in specific areas, such as the palms, feet, or face, or throughout the body.

Diaphoresis refers to sweating that is generally associated with a medical condition or as a response to an external factor, and while it involves sweating, it does not specifically denote excessive sweating as a standalone condition.

Perspiration and perspiring are general terms for the act of sweating and do not convey the same clinical significance as hyperhidrosis. They describe the normal physiological process rather than an abnormal condition. Therefore, hyperhidrosis is the most accurate and specific term for excessive sweating, distinguishing it from normal sweating or other related terms.
