What Is Hyperhidrosis?

Hyperhidrosis, or excessive sweating, is a condition in which the body sweats excessively in areas where there is a high concentration of sweat glands such as the hands, feet, armpits and the groin area.

Excessive sweating can occur when temperatures are cooler or at rest, but is typically worsened in the summer when the temperature rises slightly or by periods of activity and exercise.

It is estimated that 2 - 3% of the population suffers from hyperhidrosis (roughly 1 million people), with less than 40% of those affected seeking medical advice.

Excessive sweating is a common problem that can be solved easily, leaving you with dry, soft skin regardless of the heat.

Where on the body does hyperhidrosis typically occur?

Hyperhidrosis, or excessive sweating, commonly occurs in areas where there is a concentration of sweat glands, with the most frequent area being under the arms.

Hyperhidrosis can occur anywhere on the body, but frequently affected areas include:

  • Armpits
  • Hands
  • Feet
  • Face & Head
  • Groin

How can you treat hyperhidrosis or excessive sweating?

There are different ways of treating this condition, depending on how severe your case is.

These include:

  • Injectables  to block the nerves that supply the eccrine glands, which in turn prevent the glands from producing sweat
  • Iontophoresis - a safe medical procedure that involves sending mild electrical currents through water and into the skin
  • Or in extreme cases, a surgery called ETS (or Endoscopic thoracic sympathectomy). 

At the Cadogan Clinic, our preferred treatment method is to avoid invasive surgery and to treat the affected areas with injectables as we believe these to be the most effective and safe.

Whatever your personal requirements, you can rest assured that we will provide the leading UK consultants, techniques and facilities for your treatment at our state-of-the-art, purpose-built, dermatology clinic in Sloane Street, Chelsea.

Excessive sweating is also a condition associated with several medical conditions

Frequently Asked Questions

There is no definitive evidence that excessive sweating is genetic. This is a very common disorder, impacting roughly 3% of the population, or over a million individual people.

Hyperhidrosis is not a dangerous condition in and of itself, and there is actually very little evidence to show a link between excessive sweating and dehydration.

That said, it can cause a serious impact on self-esteem and self-confidence and have a negative effect on an individual's mental health and wellbeing.

Aside from seeking treatment as indicated above, the best advice for limiting excess sweat is:

  • Use a strong anti perspirant instead of deodorant
  • Wear loose fitting clothes
  • Wear armpit shields or sweat shields to protect your clothing
  • Wear socks that absorb moisture and change at least twice a day
  • Wear leather shoes, and use different pair each day
  • Avoid alcohol, spicy food or any activity likely to make your sweating worse

At the Cadogan Clinic our preferred method of treating hyperhidrosis or excessive sweating is via two methods:

  • The administration of Botox® to the overactive sweat glands. The protein acts by blocking excess nerve signals to the sweat glands, thus reducing the amount of sweat the body releases
  • The procedure blocks sweat from coming out of the sweat glands, temporarily stopping sweating. Treatments must be done indefinitely to maintain desired results

With Iontophoresis, the protocol is for 7 treatments over 4 weeks and these must be done regularly and before sweating increases to maintain results. A typical treatment programme will usually follow a format such as:

  • Week 1: 3 treatments (20mins for hands, 30 mins for feet)
  • Week 2: 2 treatments
  • Week 3: 1 treatment
  • Week 4: 1 treatment

Hyperhidrosis can be extremely effectively treated.

Following a prescribed Botox ® injection into the sweat glands, you can expect a major reduction in sweating for a period of between 6 and 12 months, after which you may choose to have further treatment.

The treatment can be administered in a variety of areas, such as the underarms, hands, feet and forehead.

Hyperhidrosis can occasionally get better with age, but this is rare.

Your results are not permanent but should last anywhere between 6 and 12 months.

If your aim is to reduce the embarrassment and inconvenience caused by overactive sweat glands but doesn't want an invasive surgical operation such as ETS (Endoscopic thoracic sympathectomy) or liposuction, then either Iontophoresis or Botox® are safe and convenient options.

Iontophoresis is suitable if your hands and feet are affected by excessive sweating. It is a painless non-invasive treatment which is quick and easily performed in the outpatient setting. You need a series of treatments to start off with, an example would be 7 sessions in 22 days, after which you go for maintenance treatments once every 3 weeks or as necessary.

This procedure requires no downtime or recovery time and you can comfortably return to work after the treatment.

Botox injections are very effective for axillary hyperhidrosis and the effects usually last for up to 12 months. Thus, you should choose Botox if you want a once-off treatment for excessive sweating that is long lasting. The procedure is comfortable and you just feel little skin pricks with each injection and just like Iontophoresis, you will resume your normal activities immediately after the procedure.

Botox and Iontophoresis treatments are suitable for people who want treatment for excessive sweating with minimal side effects. There are no serious side effects associated with these techniques and this makes Botox and Iontophoresis the best option for people who wish to avoid surgery.
