Hyperhidrosis is a medical condition that causes excessive sweating i.e., people with this condition sweat more than usual. In normal people, sweating cools the body to prevent it from overheating. But for people with hyperhidrosis, sweating occurs even when the body does not need cooling.

Many people with hyperhidrosis sweat from one or two body areas. Often, they sweat from

  • Armpits
  • Palms of their hands
  • Soles of their feet
  • Face and Chest
  • Groin areas

Even though hyperhidrosis is not a serious threat, it disrupts daily activities of people suffering from this condition. Episodes of excessive sweating occur often for no clear reason and affect social life, leading to depression and anxiety.

How to Treat Hyperhidrosis

As people with hyperhidrosis visit the dermatologist, he/she might suggest one of the below treatment options based on their condition and its cause.

Antiperspirants: The doctor may prescribe an antiperspirant with Aluminum Chloride that has to be applied to the affected skin before you going to bed.

Iontophoresis: In this treatment, the hands and feet are submerged in a bowl of water. A weak electric current is passed through the water or wet pad, blocking the sweat glands from causing excessive sweat.

Botulinum toxin (Botox injections): These injections block the nerves that trigger the sweat glands. People with hyperhidrosis need several injections for better results.

Anticholinergic drugs: These medications restrain the transmission of parasympathetic nerve impulses. People undertaking them feel improvement in about two weeks.

ETS (Endoscopic Thoracic Sympathectomy): This surgical intervention is recommended in severe cases that have not responded to other treatment options. Here, the nerves that carry messages to the sweat glands are cut, preventing excessive sweating. It is used to treat hyperhidrosis of the face, hands or armpits. However, it is not recommended to treat hyperhidrosis of the feet as it might cause permanent sexual dysfunction.
