My hands sweat all the time

Normally everybody sweats in response to heat, extra physical work done or some anxiety. But some people sweat a lot (hyperhidrosis) even in an ambient or cold temperature or when relaxed and calm In majority of these cases of hyperhidrosis, no apparent reason is found, i.e. primary hyperhidrosis. Hereditary factors are said to be involved in part for this type of sweating. This occurs mostly due to eccrine sweat glands which are located more in number in the feet, palms and underarms, hence the sweating occurs mostly in these parts, making the affected person feel uncomfortable. Obesity, pregnancy, menopause, are some other conditions which can cause excess sweating. It is temporary and stops after one delivers or after menopause or extra weight is shed. Treatment consists of using on the counter or prescription antiperspirants containing aluminium. Botox injections are also useful, particularly for underarms. Iontophoresis is yet another treatment available for excess sweating, where low intensity electric current is passed to destroy the sweat glands. Drugs are available which can reduce excess sweating by reducing the nerve stimulation of sweat glands. However they cause uncomfortable side effects like drying of mouth, blurred vision, e.t.c.
