Hyperhidrosis is a medical condition characterized by excessive sweating. It is not a fight or flight disorder, although it can be triggered by stress or anxiety. Hyperhidrosis is a condition in which the body produces an excessive amount of sweat, usually in the palms, soles of the feet, armpits, and face. This can be caused by a number of factors, such as genetics, hormones, medications, or environmental factors. Treatment options for hyperhidrosis include antiperspirants, iontophoresis, botox injections, and surgery. While stress and anxiety can exacerbate the symptoms of hyperhidrosis, these are not the underlying cause of the condition.
