Season 3: Episode 4: ETS

Sweating is normal. It keeps your body cool and helps regulate temperature. But what happens when your body sweats far more than it needs to?

In this episode of Tumor Minutes, Netra explores Hyperhidrosis, a condition that causes excessive sweating even when the body does not need to cool down. For people with severe hyperhidrosis, everyday things like shaking hands, holding a pencil, or using a phone can become surprisingly difficult.

The episode focuses on Endoscopic Thoracic Sympathectomy, a procedure that targets part of the Sympathetic Nervous System responsible for triggering sweat glands. By interrupting these nerve signals, surgeons can dramatically reduce sweating in certain areas of the body.

Netra explains how the surgery works, why doctors usually try other treatments first, and what patients may experience after the procedure. Along the way, she breaks down complex medical concepts into simple explanations and adds a few light jokes about the human body’s very enthusiastic cooling system.

If you have ever wondered why we sweat, how the nervous system controls it, or how surgery can change nerve signals, this episode answers those questions in a clear, engaging, and approachable way.
