Focal hyperhidrosis
Focal Hyperhidrosis
Focal hyperhidrosis (pronounced: fo-kal hy-per-hi-dro-sis) is a medical condition characterized by excessive and unpredictable sweating in specific areas of the body. The term is derived from the Greek words "hyper" meaning over or above, and "hidrosis" meaning sweating.
Definition
Focal hyperhidrosis is a subtype of Hyperhidrosis, a condition that causes excessive sweating. Unlike generalized hyperhidrosis, which affects the entire body, focal hyperhidrosis is localized to specific areas. These areas often include the palms (Palmoplantar hyperhidrosis), soles, underarms (Axillary hyperhidrosis), face (Facial hyperhidrosis), and scalp.
Causes
The exact cause of focal hyperhidrosis is unknown, but it is believed to be related to overactivity of the sympathetic nervous system. Certain triggers such as stress, heat, or physical activity can exacerbate the condition.
Treatment
Treatment options for focal hyperhidrosis include topical treatments, oral medications, Iontophoresis, Botox injections, and in severe cases, surgery (Endoscopic thoracic sympathectomy).
