What is the term for excessive sweating?

The correct term for excessive sweating is hyperhidrosis, which specifically refers to an abnormal increase in sweating that can occur in various situations or can be generalized across the body.

While "diaphoresis" is a term often used in medical contexts to refer to perspiration, particularly when it's induced by an underlying health condition, it doesn't specifically denote the condition of excessive sweating itself. Instead, it can refer to sweating due to fever, stress, or illness.

"Perspiration" is a general term for the process of sweating and does not imply any abnormality or excess, which makes it a more neutral term.

"Fever," on the other hand, is a condition characterized by an elevation in body temperature and can lead to increased sweating as a symptom, but it is not a term related to the act of sweating itself.

In summary, hyperhidrosis is the most accurate term for chronic excessive sweating, ensuring clarity in identifying it as a specific medical condition.
