Hyperhidrosis is a condition that is characterised by sweating more than is necessary to regulate our body’s temperature. Hyperhidrosis can either be general, or localised to specific parts of the body. Hands, feet, armpits, and the groin area are the regions that perspire most, due to the high number of sweat glands in these areas. Localised excessive sweating is referred to as primary hyperhidrosis or focal hyperhidrosis. Excessive sweating involving the whole body is called generalised hyperhidrosis or secondary hyperhidrosis.
Botox is an effective treatment for excessive sweating. It works by blocking the stimulation of sweat glands and the nerves that are responsible for activating them. The treatment lasts over 6 months, and patients should notice improvement within 4 weeks.
The treatment requires about 15 injections in each underarm with a very fine tiny needle. The procedure takes about 15 minutes, but you will be in the office for about 45 minutes. The clinical studies on Botox for excessive sweating found that 80% of patients reported a 50% reduction in underarm sweating at 4 weeks after the treatment.
