Cause & concerns


Most cases of hyperhidrosis are genetic, with no readily identifiable cause. This is known as primary hyperhidrosis.


Hormonal imbalance (such as that caused by thyroid dysfunction and menopause) is a known cause of secondary hyperhidrosis.


Certain medications can cause excessive sweating as a side effect.

Other illnesses

Specific illnesses including malignancy and neurological disease can cause excessive sweating.

Any new sweating, one sided sweating, or night-time sweating must be investigated by your GP.

Treatment Options

Anti-sweat injections

Anti-sweat injections effectively switch off sweat glands for up to 12 months.

They are a fast, convenient treatment that can be done on your lunch break.

This treatment uses a weak electrical current passed through the problem area to reduce sweating. It must be done a few times per week, and may cause skin irritation.

Topical drying agents

These anti-perspirants include those containing aluminium chloride, glycopyrolate and oxybutinin.

Oral medications

Anticholinergic medications reduce activity in the nerves that control sweat glands. However they have a high incidence of side effects including dry mouth, constipation and blurred vision.

    Hyperhidrosis is a medical condition where you produce more sweat that normal.

    It can be primary, where there is no identifiable cause; or secondary, where it results from another condition or medication side effect.

    Excessive sweating treatments are a simple procedure that can be done by a doctor or nurse. The specialties that usually perform this treatment are dermatologists, or more commonly a cosmetic doctor.

    Seeing a cosmetic doctor is advantaageous, because it is usually lower cost, does not require a GP referral and there is a much shorter waitlist compared to a specialist Dermatologist.

    We can treat excessive sweating in many areas of the body, including:

    • Face
    • Forehead
    • Brow
    • Scalp
    • Nape of neck
    • Upper lip
    • Underarms
    • Hands
    • Groin

    Treating excessive sweating with scientifically proven options is low risk. Most side effects are rare, temporary, and go away if treating is stopped.

    There is often no known reason for excessive sweating. Primary hyperhidrosis is characterised by excessive sweating above and beyond what would be considered normal due to overactive sweat glands where no cause can be found.

    Secondary hyperhidrosis describes excessive sweating with an identifiable cause or medical condition. This may include, among other things, medical diseases like thyroid, diabetes, and neurological problems. If you have any concerning symptoms or sweat on one side or at night, then you should see your local doctor for an assessment.

    Some cases of hyperhidrosis are genetic, while others are acquired. Medical causes of hyperhidrosis should be excluded before sweat reduction treatment.
