What causes excessive sweating?

Sweating is a normal physiological response when we become hot during our daily activities or exercise – sweating helps to cool down our bodies. Sometimes these sweat glands start to over function without any obvious trigger causing excessive sweating.

This condition is also known as hyperhidrosis. Sweating can occur at unwarranted times and can significantly deteriorate the quality of life. This can be a great source of social anxiety and embarrassment.

Symptoms of Hyperhidrosis

Hyperhidrosis typically presents as:
  • Excessive armpit sweating
  • Excessive forehead sweating
  • Excessive Scalp sweating
  • Excessive Hand sweating
  • Excessive Feet sweating


It can be classified into two types mainly:

1. Primary hyperhidrosis:

Most of the people have a genetic inclination for hyperhidrosis and include 30-50% of the affected population*. In the majority of these patients, the cause is unknown.

2.Secondary hyperhidrosis:

The condition may also arise due to an underlying health condition. The most common diseases causing excessive sweating include hyperthyroidism, obesity, adrenal gland disorders, and Parkinson’s disease. These patients are generally treated with the NHS and treatment normally involves treating the underlying health condition as well as using muscle relaxing injections to treat excessive sweating.

At Dr Leah Clinic we offer excessive sweating treatment for primary hyperhidrosis only so before presenting for excess sweating treatment we ask that clients have had causes of their excessive sweating investigated by GP to rule out medical cause (secondary hyperhidrosis).
