Excessive Sweating: When Is It Normal and When Is It a Medical Condition? By: Dr. Asmaa Al Khatib Specialist Dermatologist – Quttainah Specialized Hospital, Dubai

Sweating is a natural body function that helps regulate temperature, but in some cases, it can turn into a medical condition known as hyperhidrosis. This condition can severely affect quality of life and daily activities. Dr. Asmaa Al Khatib, Specialist Dermatologist at Quttainah Specialized Hospital in Dubai, shares her insights on how to differentiate normal sweating from a medical problem, available treatments, and when it’s time to seek medical help.

What are the common symptoms that differentiate normal sweating from hyperhidrosis?

Dr. Asmaa Al Khatib:
“Normal sweating is the body’s way of cooling itself, usually triggered by heat, physical activity, or emotional stress. Hyperhidrosis, however, is excessive sweating that goes far beyond what is needed for thermoregulation. The main differences are the amount and the location of sweating.

In hyperhidrosis, sweating often occurs in focal areas like the palms, soles, underarms, or forehead, and it may happen even in cool environments or without physical exertion. Patients often report that it disrupts their daily lives — making it hard to hold a pen, shake hands confidently, or wear certain clothes due to sweat stains.”

How does a procedure like Thoracoscopic Sympathectomy help patients suffering from excessive sweating?

Dr. Asmaa Al Khatib:
“While dermatologists don’t perform Thoracoscopic Sympathectomy, we often refer patients to surgeons when other treatments fail. This minimally invasive surgery targets the sympathetic nerves that overstimulate sweat glands, particularly in the hands and armpits.

By interrupting the nerve signals, it helps reduce excessive sweating and can provide long-term relief for severe, treatment-resistant cases — especially palmar or craniofacial hyperhidrosis. However, patients must be aware of potential side effects, such as compensatory sweating in other areas of the body.”

When should someone seek medical advice for sweaty palms and forehead instead of dismissing it as nervousness?

Dr. Asmaa Al Khatib:
“If sweating is frequent, unpredictable, and interferes with everyday activities or quality of life, it’s time to see a doctor. Unlike occasional nervous sweating, primary hyperhidrosis usually starts in adolescence, is symmetrical (both palms or both sides of the forehead), and occurs even at rest.

Many people suffer in silence, assuming it’s just part of their personality or stress response. But effective treatments exist — from prescription-strength antiperspirants and oral medications to Botox injections, and in severe cases, surgical referral. The most important thing is not to ignore the problem, because help is available.”
