The prevalence of hyperhidrosis is reported to be around 1%. This figure is thought to be much higher since the majority of cases are not reported to primary care (1).
- according to a large American national survey, only 38% of patients with a primary pattern of symptoms had consulted a health professional
- it is estimated that there is a 15 year delay in presentation of patients with hyperhidrosis to primary care
The disease is seen in equal ratios among the sexes and may be seen at any age:
- the mean age of onset was 14 years old
- in teenagers, the estimated prevalence is 1.6%
- children tend to present with palmoplantar hyperhidrosis
- axillary hyperhidrosis (linked to the development of sweat glands) is commonly seen after the onset of puberty
In 30% to 50% of cases of primary hyperhydrosis, a family history is reported (2).
