Although neurologic, metabolic and other systematic health conditions can sometimes cause excessive sweating, people who are otherwise healthy can also suffer from it. factors like exercise, temperature of surroundings, certain food and beverages, stress and emotions (anger, embarrassment, nervousness) may trigger excessive sweating. Sufferers of hyperhidrosis appear to have overactive sweat glands, and may sweat uncontrollably even when the temperature is cool or when they are at rest.
Hyperhidrosis may be congenital or an acquired trait, and is categorised as follows:
Primary Idiopathic Hyperhidrosis
There is no apparent cause for excessive sweating (idiopathic means “of unknown cause”). In the majority of cases the hyperhidrosis is localised and found to start during adolescence, or seems to be inherited as an autosomal dominant genetic trait.
In this case, the condition can start at any point in life, due to an underlying health condition, such as menopause, obesity, gout, tumour, diabetes mellitus or hyperthyroidism (overactive thyroid gland), certain medication or mercury poisoning. generalised hyperhidrosis is more common among people with this condition.
