Hyperhidrosis

There are two types of hyperhidrosis, each having a different cause:

Primary hyperhidrosis

With primary hyperhidrosis the excessive sweating appears to be the result of the brain sending incorrect messages through the sympathetic nervous system to stimulate the sweat glands, even when there is no need to cool the body. Why this happens is unknown.

Primary hyperhidrosis can be a genetic condition (passed on through families) but it can also be triggered by other factors such as hormonal changes or stress.

Secondary hyperhidrosis

Secondary hyperhidrosis is caused by an underlying medical condition or side effects of taking medication.

If you experience hyperhidrosis you should always speak to your doctor to rule out any underlying conditions.

Sweating is a perfectly normal reaction to your body temperature rising – for example in hot weather or if you’re doing exercise. However, for people with hyperhidrosis, their body produces sweat in excess, even when their body doesn’t need to be cooled.

Primary hyperhidrosis

In the case of primary hyperhidrosis, it mainly affects the hands, feet and underarms. The face, scalp, back, neck, chest, groin, legs and buttocks can also experience excessive sweating.

Primary hyperhidrosis sufferers don’t sweat excessively when asleep, so this is a useful way of distinguishing it from other conditions such as hormonal hot flushes.

Primary hyperhidrosis affects both sides of the body equally and generally begins in childhood or adolescence.

Secondary hyperhidrosis

Secondary hyperhidrosis, caused by an underlying condition or medication, tends to begin in adulthood.

It affects the body more generally (rather than in specific areas) and the sweating will usually continue even when the sufferer is asleep.

There are several ways to manage the effects of hyperhidrosis, although there is not currently a cure available. Some people find that the symptoms reduce as they age (although they can worsen for others).

Antiperspirants

Antiperspirants (rather than deodorants) can be effective in managing hyperhidrosis, particularly formulas containing aluminium chloride. However, care should be taken why applying them to sensitive skin, for example your forehead or groin.

Medication

Medication (usually taken in tablet form) may also help to reduce sweating. It works by blocking the nerve signals which activate the sweat glands. However, it can have side effects of blocking other nerve signals and, as a result, can cause problems such as dry mouth and constipation.

Iontophoresis

This process uses a low voltage electrical current passed through water directly into the area to be treated. This can be a helpful treatment for sweating of the hands, feet or underarms.

Surgery

There are surgical options for hyperhidrosis sufferers, including removal of the sweat glands and cutting of the nerves which control sweating (although this should only be considered as a last resort).

Lifestyle changes

Clothing

Wearing loose fitting, cotton or linen clothing can help to keep your body naturally cool and lessen the risk of excessive sweating. You can also wear absorbent sweat shields under your clothes to contain the perspiration.

Black or white clothes will disguise sweat marks better than colourful clothing.

Avoid shoes made of synthetic materials, particularly close fitting sports shoes. Leather shoes are a good choice or sandals. Change your socks regularly and choose ones made from natural fibres such as cotton.

Diet

Some people find that they have particular triggers which can worsen the condition and, therefore, can be avoided. Typical triggers include alcohol, caffeine, spicy food and strong smelling food.

Cosmetics

Avoid harsh soaps and instead use emollient washes and creams.

Stress

Stress is often a contributing factor. Seeking help in managing your stress, for example through counselling or relaxation exercises, can lessen hyperhidrosis attacks.

Botox injections

To help manage the symptoms of hyperhidrosis we offer botox injections. Botox works by reducing the nerves’ ability to send messages to the sweat glands, thereby significantly reducing the production of sweat. This is effective for primary hyperhidrosis sufferers. For those with secondary hyperhidrosis, treatment results can vary. Our practitioners will thoroughly assess treatment suitability during your consultation.

Our botox treatment can be used to manage excessive sweating of the underarms, hands, feet, upper face and groin.

Botox isn’t a cure for hyperhidrosis, and regular treatments (usually every three to six months) will be required to maintain the benefits. However, it is a safe and effective way of managing the condition.
