Hyperhidrosis is a condition characterized by abnormally increased sweating/perspiration, in excess of that required for regulation of body temperature. It is associated with a significant burden on the quality of life from a psychological, emotional, and social perspective.

Hyperhidrosis is classified into two forms

Localized- when excessive sweating involves the hands, feet, armpits and groin areas.
Generalised- when the sweating is all over the body

Why does a person have hyperhidrosis?

This is caused by sympathetic over activity. Nervousness or excitement can exacerbate the situation for many people. Certain foods and drinks, nicotine, caffeine, and smells can trigger a response and increase sweating.nervous.

A common complaint of patients is that they get nervous because they sweat, then sweat more because they are nervous.

How is hyperhidrosis treated?

It is treated in two ways:


Aluminium chloride is used regularly as part of antiperspirants, however, hyperhidrosis sufferer’s need solutions or gels with a much higher concentration to effectively treat the symptoms of the condition. These antiperspirant solution or gels are especially effective to treat axillary or underarm regions.

Injections of botulinum toxin type A (BTX-A) are used to block the neural control of sweat glands. The effects last from 3-9 months depending on the site of injections. This procedure used for underarm sweating has been approved by US FDA. People see a very good benefit and are happy with the result. This is a walk-in and a walk-out procedure. It takes 2-4 weeks for best result.

Lasers are the new technology which are used in the treatment, one requires only one session and it gives relief for about one year. It ablates the sweat glands in the area treated thus reducing the excess sweating.


Radical liposuction in the axillary area to reduce the sweating. This is good for only localised sweating in the armpits. The sweat glands are destroyed for ever &there is significant reduction in the sweating permanently.

Endoscopic sympathectomy (ETS), which cuts, burns, or clamps the thoracic ganglion on the main sympathetic chain that runs alongside the spine. ETS is generally considered a safe surgery. The procedure causes relief of excessive hand sweating in about 85-95% of patients.

How is micro wave technology used for under arm sweating?

Is a quick non-invasive procedure that provides a lasting solution for excessive underarm sweating. The Laser, when placed on the underarm, delivers precisely controlled energy to the region where the sweat glands reside thus eliminating them non-invasively. The sweat glands don’t grow back once eliminated, resulting in a dramatic and lasting reduction of underarm sweat. This is only used to reduce sweating in the under-arm region.

What is the procedure like?

The procedure involves no surgical incisions or cuts. Local anesthesia is administered to the underarms prior to the procedure to maintain comfort. Your appointment will generally last about an hour. Two procedures spaced three months apart are usually required to maximize the results and duration.

What happens after the procedure?

There is minimal downtime following the procedure. The dermatologist will recommend a mild over-the-counter pain medication and use of ice packs for a few days. You should be able to return to normal activities or work right after the procedure, and can start exercises in a few days. Some localized soreness or swelling and short-term altered sensation in the skin of their underarms or upper arms, is to be expected which gradually disappears.

What results can I expect?

Most patients report a dramatic reduction of their sweat – usually to the extent of 70-90%. You should see a reduction in sweat immediately after treatment. As with any medical procedure, results will vary between people to people.

How long will the results last?

The results are long lasting because the sweat glands do not come back or regenerate after they have been eliminated. This is the only safe US FDA approved technology which gives long lasting sweat reduction.

Is reducing under arm sweating permanently, safe?

Your body contains over 4 million sweat glands which produce sweat under control of sympathetic system. This is usually to control the body temperature. Underarm has only about 2% sweat glands which causes hyperhydrosis. Eliminating these 2% will not affect the body’s ability to cool itself.
