Hyperhidrosis is the production of sweat in high quantity more than normally (physiologically) produced and needed for regulation of body temperature. When its localized to a specific part of the body then its referred to as primary focal hyperhidrosis. It can be idiopathic or secondary to disease or medication.
The criterias for diagnosing primary focal hyperhidrosis are:
It has to be focal, visible and excessive sweating of not less than six months without any obvious reason.
Hyperhidrosis is a disease in which an individual suffer from sweating that exceed normal level. The common sites associated with excessive sweating are armpits, palms, sole, scalp, infra-mammary area and groin region. Many researches had been conducted on …show more content…
the prevalence of hyperhidrosis abroad but none was done here in UAE. Some of the researches include:
In japan(2013), a study conducted between people aged 5-64 years, received 5807 valid responses, from which the prevalence shows that 5.33% have palmar hyperhidrosis, 2.79% have plantar hyperhidrosis, 5.75% have axillae hyperhidrosis and 4.7% head hyperhidrosis.
It was estimated that 616,000 of patient with severe symptoms have primary palmar hyperhidrosis while 2,239,000 have primary axillae hyperhidrosis in japan.
Also the study showed that most of the patients suffer decreased quality of life, but unfortunately only 6.2% of them seek help from professional.

In USA(2004), a survey to screened 150,000 household for hyperhidrosis was done. Among the participant(sample) 2.9% have hyperhidrosis. With this the estimated prevalence of hyperhidrosis in the United States of America was seven million eight hundred thousand individual (2.8%). Among which approximately 50% have axillae hyperhidrosis ( four million) and halve of this individual did not seek any medical assistance.
Proquest)Another study to determine the prevalence of hyperhidrosis between outpatient in Shanghai and Vancouver. A total of 14336 participants between the age of 16-70 years were received. The study showed that the prevalence of hyperhidrosis was 16.3%(2340). in which 6.1% of them have decreased quality of live as they complained of continuous sweating. Prevalence of hyperhidrosis was higher in men than women. Among the 2340 participant with hyperhidrosis, 68% have generalised hyperhidrosis. While the remaining are focal hyperhidrosis, with hand 23%, axillaries 44%, feet 29% and 34%
others.
As age increases, the prevalence of focal hyperhidrosis decreases, whereas generalized hyperhidrosis increase with age. There were differences in comorbidity between patient that have hyperhidrosis and does without. For example 3% of those with hyperhidrosis have tenea pedis while 2.1% in those without hyperhidrosis. Onychomycosis, 8.5% in those with hyperhidrosis and 6.1% in those without it, Psoriasis 3% in those with hyperhidrosis and 2.1% in those without it.
Proquest
The study showed that Shanghai and Vancouver had similar prevalence of primary hyperhidrosis at 14.5% and 12.3% respectively. 4% of participant in shanghai suffer from late onset of hyperhidrosis which also had similar in Vancouver.
The highest prevalence of hyperhidrosis was among those in 30 years of age, and it decreases in later age. Caucasian participant are 2.5 times least likely to have axillae hyperhidrosis in comparison with Chinese. No variation in prevalence of hyperhidrosis between obese subjects from both places, but it increases the risk of late onset hyperhidrosis. And no difference between Chinese subjects in shanghai and in Vancouver.
