Hyperhidrosis FAQs: Your questions answered by a specialist

Hyperhidrosis, a condition characterised by excessive sweating, can cause discomfort and may affect a person’s self esteem if they are embarrassed by their symptoms. In this informative guide, highly respected consultant thoracic surgeon Mr Marco Scarci answers commonly asked questions about hyperhidrosis, including how the condition affects the body and the available treatment options.

What is hyperhidrosis?

Hyperhidrosis is a medical condition which causes to profuse perspiration (sweating) which exceeds the amount required to regulate the body’s temperature. This perspiration can manifest in particular areas of the body, such as the palms of the hands, the soles of the feet or underarms, as well as the face and head. Patients with hyperhidrosis may find the condition embarrassing and, in some cases, may also suffer from discomfort and related skin irritation or infection.

Various factors, including hormonal changes, neurological conditions, or certain medications, may cause it. Treatments for hyperhidrosis can range from antiperspirants and medication to surgery or other medical procedures.

Which parts of the body are affected by hyperhidrosis?

Excessive sweating caused by hyperhidrosis can affect different parts of the body, including:

• armpits
• palms of the hands
• soles of the feet
• face and forehead
• groin area

Although excessive sweating with hyperhidrosis most often occurs in the underarms, palms of the hand and soles of the feet, it can present in any part of the body. In patients where the whole body is affected, the condition is known as generalised hyperhidrosis.

Does hyperhidrosis run in families?

Yes, hyperhidrosis can run in families. According to medical research, about thirty to fifty per cent of people with hyperhidrosis have a family history of the condition. If you are concerned about any symptoms you are experiencing, or have a family history of the condition, you should seek an appointment with a specialist who can provide an accurate diagnosis and suitable treatment, if required.

How is hyperhidrosis diagnosed?

In order to establish a diagnosis of hyperhidrosis, your medical professional may perform a physical examination, review your medical history, and ask you about your symptoms. For some patients, a sweat test may be used to measure how much sweat is being produced by the body. Additionally, blood tests or imaging may be used to rule out any underlying medical conditions that may be causing excessive sweating. If you are experiencing excessive sweating or other symptoms, you should seek medical advice.

What are the treatment options for hyperhidrosis?

There are various treatment options for hyperhidrosis, including:

Antiperspirants

Over-the-counter antiperspirants (a specialist type of deodorant) which contain aluminium chloride can help to control perspirations.

Medications

A type of medication called anticholinergics (such as Glycopyrrolate) can help to reduce sweating. However, it is important to note that side effects such as dry mouth, constipation, and blurred vision may occur.

Iontophoresis

Iontophoresis is a type of procedure performed with a medical device that uses electric currents to temporarily shut down the sweat glands in the affected area.

Botox injections

Botox can be injected into the affected area to block the nerves that control sweat production.

Surgery

In severe cases, surgery may be recommended to remove the sweat glands or alter the nerves that control sweating. It is important to consult with a medical professional to determine the best course of treatment for your individual case.

Can hyperhidrosis be cured?

Although hyperhidrosis cannot be cured completely, there are a number of treatment options available that can help patients to manage their symptoms. Over-the-counter antiperspirants or prescribed medications may be helpful for some patients, while in other cases medical procedures like iontophoresis, Botox injections or surgery may be indicated. Your medical specialist will advise you of the most suitable treatment in your individual case.

Does anxiety cause hyperhidrosis?

Hyperhidrosis may be related to a number of factors, including:

• genetics
• side effects from medications
• hormonal imbalances

Hyperhidrosis can also be related to other medical conditions, including anxiety disorder. As anxiety and stress can cause the body to release more sweat, they may contribute to symptoms of hyperhidrosis. A healthcare professional can help you determine the exact cause of your hyperhidrosis and develop a treatment plan tailored to your specific needs.

Does hyperhidrosis smell?

Hyperhidrosis, or excessive sweating, does not have a naturally unpleasant smell. However, a build-up of sweat and bacteria on the skin can cause an unpleasant odour. This is particularly true in areas of the body that are prone to sweating, such as the armpits and feet. If you are worried about odours related to your symptoms, it is advisable to maintain good personal hygiene, wear breathable clothing and use antiperspirants. A specialist can also help you find a suitable treatment option.

Is hyperhidrosis considered a disability in the UK?

Hyperhidrosis may be considered a disability under the UK Equality Act of 2010 if it has a significant impact on a person's daily life and ability to carry out normal activities. As a result, patients with hyperhidrosis may be entitled to certain rights and protections under the law, such as reasonable adjustments in the workplace or public accommodations. However, each case must be considered individually based on the severity and impact of the condition on the individual's daily life. For personalised guidance and support, you should see a specialist doctor and medicolegal expert.
