Excessive Sweating
Hyperhidrosis is a medical condition that causes excessive sweating beyond what the body needs to stay cool. While it’s normal to sweat during exercise, heat, or stress, people with hyperhidrosis may sweat heavily even when they’re at rest or in cool temperatures.
This condition can affect specific areas such as the underarms, hands, feet, face, or scalp, or it may occur across larger areas of the body. The excessive moisture can interfere with daily activities, cause discomfort, and sometimes lead to skin irritation or social embarrassment — but effective treatments are available.
Types of Hyperhidrosis
Primary (focal) hyperhidrosis:
This is the most common type. It usually begins in childhood or adolescence and affects specific areas like the palms, soles, underarms, or face. It’s not caused by another medical condition.
Secondary (generalized) hyperhidrosis:
This type results from an underlying medical issue (such as thyroid problems, diabetes, or menopause) or certain medications. It often causes sweating over larger areas of the body.
