Sweating is a normal physiological response to increased body temperature (heat, exercise, fever) or emotional stress. Hyperhidrosis is a medical term for an overactivity of the sweat glands, resulting in excessive sweat production. This means that individuals with hyperhidrosis sweat excessively, even in conditions that don’t typically warrant such a response. It primarily affects the underarms but can also occur on the palms, soles of the feet, forehead, and more.
Excessive underarm sweating leads to visible sweat stains and body odor, while sweaty hands can interfere with daily activities such as driving, holding objects, or physical contact. Excessive foot sweating increases the risk of fungal infections. Hyperhidrosis can significantly impact self-confidence and daily life.
