Why do I sweat more than everyone else?

Excessive sweating without any underlying medical condition is called primary hyperhidrosis. If the cause of excessive sweating is due to a medical condition, this is referred to as secondary hyperhidrosis. Hyperhidrosis (HH) is caused by increased release of a chemical (acetylcholine) which causes sweat glands to produce excessive perspiration, most commonly palms, soles, and underarms (axilla).

It can significantly affect the social and psychological wellbeing of an individual. For some individividuals, it may cause physical discomfort, social embarrassment, affect occupational and daily activities, and at times social isolation. Many who have the problem find it embarrassing, trying to avoid shaking hands and hiding sweat stains by wearing black or jackets even during Summer.

Treatments to stop excess sweating

Treatment options available for treatment of hyperhidrosis include:

Antiperspirants/deodorants: Aluminium chloride hexahydrate in antiperspirants block the sweat pores and best applied onto clean dry skin at night. Irritation and itching of skin can be an unwanted side effect.

Medications:Agents that inhibit release of acetylcholine such as glycopyrrolate lotion and tablets can be prescribed by a doctor specialising in excess sweating. These agents may cause dry mouth, dizziness and other side effects.

Iontophoresis:A small electric current is passed through a solution (tap water/ glycopyrollate) and temporarily blocks the sweat glands. Treatment is weekly and can be fortnightly depending on your response. Click here for more information.


Injections : This has been used in Australia for over 20 years for medical conditions including cerebral palsy in children. It is a purified protein that blocks release of acetylcholine. Topical anaesthetic cream can be applied prior.  Most patients notice a dramatic benefit within 7 days and remain dry for 4 months or longer.

Medicare rebate is  available for axillary hyperhidrosis in patients 12 years or older. Click here for more information.

Surgery: Surgery may be performed to remove the sweat glands or to interrupt the impulses from the central nervous system in a procedure called Endoscopic thoracic sympathectomy (ETS). The ETS procedure is considered a last resort as it may cause compensatory or excessive sweating at another location. Please ask your GP to refer you to a surgeon to discuss this further.

Miradry is another long term option available at some specialised medical clinics.
