Primary focal hyperhidrosis is a chronic skin disorder that results in excessive sweating in certain areas of the body, such as the armpits, hands, feet, head, face, scalp, inguinal, and inframammary areas and groin. The condition is also known as idiopathic hyperhidrosis and is thought to be caused by increased cholinergic activity on eccrine sweat glands. Primary focal hyperhidrosis is a relatively common disease that is inherited from family members through a mutation in their genes. It usually begins early in life or during teenage years and is characterized by excessive sweating in amounts greater than what is needed to regulate body temperature. Unlike secondary hyperhidrosis, which is caused by an underlying disease, primary focal hyperhidrosis occurs for no apparent reason. The most commonly affected areas in primary focal hyperhidrosis are the armpits, hands, and feet, but it may also affect other areas of the body such as face, scalp, forehead, and the groin area. This condition can cause significant social anxiety and embarrassment, as well as disrupt daily activities. Fortunately, primary focal hyperhidrosis is treatable. Topical aluminum chloride-based antiperspirants, iontophoresis, botulinum toxin injections, oral medications, miraDry, and surgery are some of the treatment options available.
