Hyperhidrosis disorder is a condition that results in excessive sweating. This sweating can occur in unusual situations, such as in cooler weather, or without any trigger at all. It can also be caused by other medical conditions, such as menopause or hyperthyroidism.
Hyperhidrosis can be uncomfortable. However, several treatment options can provide some relief.
About 4.8 percent of Americans have hyperhidrosis, but this figure may be underreported. Many don’t seek treatment because they don’t realize they have a treatable medical condition.
Types and causes of hyperhidrosis
Sweating is a natural response to certain conditions, such as warm weather, physical activity, stress, and feelings of fear or anger. With hyperhidrosis, you sweat more than usual for no apparent reason. The underlying cause depends on which type of hyperhidrosis you have.
Primary focal hyperhidrosis
Sweating mainly occurs on your feet, hands, face, head, and underarms. It usually starts in childhood. About 30 to 50 percent of people with this type have a family history of excessive sweating.
