Excessive Sweating


Hyperhidrosis is excessive sweating that may or may not have an underlying cause.

Types of hyperhidrosis

  • Primary hyperhidrosis (also called focal, or essential, hyperhidrosis) causes excessive sweating in the hands, underarms, face, and feet without any apparent reason.
  • Secondary hyperhidrosis (also called generalized hyperhidrosis) causes excessive sweating all over the body or in a larger area of the body and can be caused by excessive heat as well as a medical condition or medication.

Treatment of  hyperhidrosis

The major therapeutic options for axillary hyperhidrosis include antiperspirants, botulinum toxin, microwave thermolysis.

  • First-line therapy — Topical antiperspirants are the preferred initial treatment for axillary hyperhidrosis because they are widely available.
  • Second-line therapy — Patients who do not achieve sufficient improvement in axillary hyperhidrosis with topical antiperspirants may benefit from botulinum toxin injections.
