Excess Sweating

Hyperhidrosis, or excessive sweating, is a relatively common condition affecting around 3% of the population. Most commonly triggered by heat and emotions, hyperhidrosis usually occurs in areas of the body with a higher concentration of sweat glands such as the armpits, hands, feet and the groin area.

Primary hyperhidrosis refers to heavy sweating without any underlying medical conditions. It occurs due to hyperactivity of the sweat gland stimulating nerves.  In most cases, it is hereditary.  Secondary hyperhidrosis is excess sweating due to an underlying medical condition. Conditions that may cause secondary hyperhidrosis to include leukaemia, heart attack, fever, and diabetic hypoglycemia.  Menopause, obesity, generalized anxiety disorder and stress are other causes.

Most common areas to suffer from excessive sweating are the underarms (axillary hyperhidrosis), the palms and soles of the feet (palmoplantar hyperhidrosis). Underarm problems tend to start in late adolescence, while palm and sole sweating often begins earlier, around age 13 (on the average). Untreated, these problems may continue throughout life.

Sweating is embarrassing; it stains and rots clothes, ruins romance, and complicates business and social interactions. Severe cases can have serious practical consequences as well, making it hard

What Causes Hyperhidrosis?

Although neurologic, endocrine, infectious, and other systemic diseases can sometimes cause hyperhidrosis, most cases occur in people who are otherwise healthy. Heat and emotions may trigger hyperhidrosis in some, but many who suffer from hyperhidrosis sweat nearly all their waking hours, regardless of their mood or the weather.

What is the Treatment for Hyperhidrosis?

Iontophoresis works well for the hands and feet. It is a painless non-invasive treatment which is efficiently performed as an outpatient. You will have a series of treatments usually 7 sessions in 22 days followed by maintenance treatments as necessary.

This procedure requires no downtime or recovery time and you can comfortably return to work after 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 one-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 options for people who wish to avoid surgery.

Liposuction and curettage of the (axillae) armpits is generally a one-off surgical treatment carried out under local anaesthesia (sedation if you prefer). The principle is that all the sweat glands are removed and once removed will not regenerate. It does not work elsewhere in the body.

We no longer recommend Endoscopic thoracic sympathectomy. It is a big procedure and has too many risks.
