Side Effect: Excessive sweating (hyperhidrosis)
What is Excessive sweating (hyperhidrosis)?
Excessive sweating, also known as hyperhidrosis, is a condition characterized by an abnormal amount of sweating beyond what is necessary to regulate body temperature. It can occur in various parts of the body, such as the palms, feet, armpits, and face, and can significantly impact a person’s quality of life.
Hyperhidrosis can be primary or secondary:
- Primary hyperhidrosis is due to overactive sweat glands and typically affects specific areas of the body.
- Secondary hyperhidrosis is usually a result of an underlying medical condition such as cancer, infection, or hormonal imbalances and may cause sweating all over the body.
