In a survey mailed to 150,000 households, 2.9% reported that they experienced excessive or abnormal/unusual sweating.
About half reported axillary hyperhidrosis. Approximately one-third of individuals with axillary hyperhidrosis reported that either their sweating is barely tolerable and frequently interferes with daily activities or is intolerable and always interferes with daily activities.
Hyperhidrosis affects a much larger proportion of the general population than previously reported.
