Sweating is a normal body function and is necessary to keep our bodies from overheating. When the temperature rises, you exert yourself, or you are stressed or anxious, you sweat more, but if you find yourself sweating all the time and more than average, then you may have a condition known as hyperhidrosis or excessive sweating.

Hyperhidrosis can be a highly embarrassing and even debilitating condition to live with. It can affect your relationships, working life and ability to participate in everyday activities. Sufferers can have to change their outfits every few hours with clothes ruined. It can have a significant impact on self-confidence.


What causes hyperhidrosis?

It is not known precisely what causes hyperhidrosis, but it seems that the nerves that control our sweat glands are more active in hyperhidrosis sufferers. It is estimated that up to 3% of men and women suffer from excessive sweating of the underarms, known as axillary hyperhidrosis, or of the palms and soles of the feet or palmoplantar hyperhidrosis.

Primary hyperhidrosis is not a symptom of a separate medical condition or a side effect of medication. It affects specific body parts such as the hands, feet, groins, underarms or head. It often runs in families and usually presents in adolescence.

Secondary, generalised hyperhidrosis is typically the result of an underlying medical cause. Unlike primary hyperhidrosis, you may often experience excessive sweating during sleep.

Unfortunately, there is no cure for primary hyperhidrosis, but there are treatments that can alleviate the symptoms. Prescription antiperspirants are usually the first recommended treatment. Other treatments include nerve-blocking medications, antidepressants, Iontophoresis, microwave therapy and surgery, although the latter has a high risk of complications.

We can treat excessive sweating with Muscle Relaxing Injections. They can be used to reduce sweating in the underarm area, the most commonly treated part of the body. Wet, clammy hands are also a common complaint that can be treated. The face and scalp are also safe to be treated.

Muscle relaxing injections are the most popular aesthetic procedure for smoothing dynamic wrinkles caused by the constant movement of our facial muscles.

It works by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. According to the International Hyperhidrosis Society, botulinum toxin is believed to reduce sweat production by 82-87% for up to six months.

The FDA has approved botulinum toxin injections for many years. In the UK, it is licensed for the treatment of axillary hyperhidrosis and may also be used for palmar, plantar, and craniofacial hyperhidrosis. It is not advised if you are pregnant or breastfeeding.

There is increasing pressure on us these days to appear ‘ageless’ and conform to celebrity ideals and this in turn can lead to confidence issues which I all too often see as a doctor.

I truly believe in a ‘less is more’ philosophy and want to work with my clients to achieve a more youthful version of themselves whilst retaining their full range of expression and not giving them a mask like look. I want your friends to comment on how well you are looking but not be able to tell that you have had a cosmetic treatment (that’s a secret that you can choose to keep to yourself)!
