Excessive Sweating (Hyperhidrosis): When It Is More Than the Heat

In Kerala's heat and humidity, everyone sweats. But some people sweat so much that their palms drip on paper, their feet slip in sandals or their shirts are soaked even in an air-conditioned room. This is hyperhidrosis, a recognised medical condition that can be treated.

What is hyperhidrosis?

Hyperhidrosis means sweating more than the body needs to stay cool. It is not caused by poor hygiene or weakness.

Primary (focal) hyperhidrosis

This is the most common type. The nerves that signal the sweat glands are overactive. It usually affects the palms, soles, underarms, face or scalp, on both sides of the body. It often starts in childhood or the teenage years, often runs in families and usually does not occur during sleep.

Secondary hyperhidrosis

This is caused by another condition or a medicine. It more often affects the whole body, may start in adulthood and can happen during sleep. Causes include thyroid overactivity, diabetes, menopause, infections, some medicines and, rarely, other serious conditions.

Signs it may be hyperhidrosis

• Visible sweating without heat, exercise or anxiety
• Wet palms that make writing, using a phone or shaking hands difficult
• Sweat stains that soak through clothes
• Frequent fungal infections, foot odour or skin softening on the feet
• Sweating that affects work, studies or confidence

When to see a doctor promptly

• Sweating that started suddenly in adulthood
• Night sweats that soak the bed
• Sweating with weight loss, fever, palpitations or tremor
• Sweating on one side of the body only

These need medical assessment to look for an underlying cause.

Daily tips that help

• Apply antiperspirant to dry skin at night, when sweat glands are less active
• Wear loose cotton or moisture-wicking clothing
• Choose breathable footwear, change socks during the day and alternate shoes
• Use absorbent powders on the feet and in body folds
• Carry a handkerchief or tissue for the palms

Treatment options

Treatment depends on the area affected and how severe it is. At Dr. Lasi's, hyperhidrosis treatment options include:

• Prescription-strength antiperspirants containing aluminium chloride
• Iontophoresis: the hands or feet are placed in shallow water through which a mild electrical current passes; sessions are repeated several times a week at first, then less often
• Botulinum toxin injections: reduce sweating in the underarms and other areas for several months
• Oral medicines for selected patients, with attention to side effects
• Referral for surgical options in rare, severe cases

Living with hyperhidrosis

Many people hide excessive sweating for years because they are embarrassed. It is a common, treatable condition, and most people find a combination of measures that gives them good control.
