Excessive sweating: causes, symptoms and treatment

Excessive Sweating also known as ‘Hyperhidrosis’, is a common condition of heavy sweating in certain areas of the body, such as the underarms, palms, and feet.

Excessive sweating: What you need to know

Excessive sweating, medically referred to as ‘Hyperhidrosis’, can profoundly affect self-consciousness and be a seriously embarrassing condition. When severe sweating interferes with daily activities, it can cause great emotional and psychological upset, especially when it is sweating from the underarms. It is estimated that up to 5% of the population suffers from some form of hyperhidrosis during their lives.


This condition is commonly found in certain areas of the body such as underarms, palms and feet and can be seen through clothing and create self-conscious concerns.

  • Botox, also known as botulinum toxin, can be used to treat excessive sweating, also known as hyperhidrosis. When injected into the skin, Botox works by blocking the chemical signals that stimulate the sweat glands. This can help reduce excessive sweating in the treated areas.

What is MiraDry?

MiraDry works by delivering precisely controlled electromagnetic energy to the underarm area, eliminating the underarm sweat glands. Two procedures are typically recommended, 3 months apart, to maximise the quality and duration of results.


While sweating is an essential body function for temperature-control, the underarms house less than 2% of the body’s sweat glands, and miraDry is completely safe and has a 79% patient. satisfaction rating on Realself.

What are the benefits of miraDry treatment?

  1. Significant reduction in underarm sweating: MiraDry can reduce underarm sweating by up to 82%, providing long-lasting results.

  3. Non-invasive and quick procedure: MiraDry is a non-invasive treatment that can be completed in about one hour. There is no downtime, so patients can resume their normal activities immediately after the treatment.
  4. Permanent results: Once the sweat glands in the underarms are destroyed by miraDry, they do not regenerate, providing permanent results.
  5. Reduction in the need for antiperspirants: Since miraDry provides long-lasting reduction in underarm sweating, it can significantly reduce the need for antiperspirants or deodorants, saving time and money.
