Sweating is your body’s normal mechanism to cool itself, but some people produce more sweat than is needed for cooling – called hyperhidrosis. This condition affects about 2 to 3 per cent of the population.
In most cases the cause of the excessive sweating is not known, so-called primary hyperhidrosis. It often starts in childhood or adolescence and tends to affect the armpits (axillae), palms and soles.
Stress and anxiety can make the sweating worse, and although the condition occurs in both warm and cool climates, it is usually worse at higher temperatures. Many people with primary hyperhidrosis have a family history of the condition.
Excessive sweating can be socially embarrassing. It may stain the clothing. Hyperhidrosis of the soles may not only result in smelly feet, but may also damage footwear. People with hyperhidrosis of the palms are often embarrassed by a cold, wet handshake. They may have trouble using keypads and other electronic equipment.
Excessive sweating can be treated with lifestyle remedies, topical antiperspirants containing aluminium salts and oral medications prescribed to reduce sweating. Occasionally injectable agents are indicated for severe, underarm sweating.
