Hyperhidrosis (excessive sweating) is a medical condition, with one or more parts of the body producing more sweat than is biologically necessary. While it is not a life-threatening condition, hyperhidrosis can significantly impact the quality of life of affected individuals, interfering with their everyday activities and emotional well-being. Hyperhidrosis can occur without any underlying cause (primary hyperhidrosis), or as a result of various medical conditions, including endocrine disorders, infections, or certain types of cancer (secondary hyperhidrosis). In cases of primary hyperhidrosis, treatment may include topical antiperspirants, oral medications, local therapies, or surgery. Despite all treatments available, primary hyperhidrosis tends to be a recurring condition that is often difficult to control. Treatment of secondary hyperhidrosis begins by addressing any underlying medical conditions or discontinuing any suspected medications.
