Background:Hyperhidrosis is a quite common condition. There is a wide variation in the reported prevalence of hyperhidrosis in the
Objectives:This study aims to examine the prevalence of hyperhidrosis.
Methods:A cross sectional survey of a population was carried out. The subjects were classified to have hyperhidrosis using the criteria of
International Hyperhidrosis Society. The prevalence of HH was calculated for the entire study population.
Result:The prevalence of hyperhidrosis was 3.2% (320 cases) in the study population of 10000.
Conclusion:Hyperhidrosis affects a much larger population than previously reported.
Keywords: Prevalence; Hyperhidrosis; Population; Cross sectional study
Hyperhidrosis (HH) is a condition characterized by excessive sweating without the usual triggers such as mental, physiological or thermal stimuli. There are two broad categories of hyperhidrosis, secondary and primary. Secondary hyperhidrosis occur with an underlying medical condition, such as chronic infections and other catabolic conditions . In contrast, primary hyperhidrosis (primary HH) occurs in a symmetrical fashion with an age of onset less than 30 years and without underlying medical conditions. While the significant negative impact of primary HH is well known, especially in developed countries , there have been large variations in the prevalence of primary HH in various reports, ranging from 2.8% in the United States , to 16.3% in Germany  and 12.8% in Japan , the reasons for the discrepancies are not known. However, the demographical and geographical aspects of various studies differ from one study to the next. Further, the criteria used for the diagnosis and classification of HH also varied from study to study.
It was a cross sectional survey carried out in a rural community in Srinagar in April 2014. The subjects were classified to have hyperhidrosis using the criteria of International Hyperhidrosis Society. The prevalence of HH was calculated for the entire study population. The questionnaire contained the following
components: age, sex, reasons for presenting for dermatological assessment, symptoms related to day-time.
Hyperhidrosis (HH) is a condition characterized by
excessive sweating without the usual triggers such as mental,
physiological or thermal stimuli. There are two broad categories
of hyperhidrosis, secondary and primary. Much of the current
knowledge is directed on treatment while only a few studies are
focused on determining the prevalence.
In our study the prevalence of hyperhidrosis was 3.2%.
The prevalence of primary hyperhidrosis has been the subject
of examination by several groups focusing on populations that
differ in ethnic compositions, geographical locations, age, and
gender. However, the findings vary from one study to the other:
2.8% in the United States , 4.4% PPH in Fuzhou, China ,
16.3% in Germany  and 12.8% in Japan . Possible reasons
for the wide variation may include differences in study methods,
precise definitions used, ethnic composition of the study
subjects, age, gender and the environment.
Females were the dominant sex affected in our study and
also axillary hyperhidrosis was the commonest site affected. Also
majority of the patients had positive history of hyperhidrosis.
Further studies are needed to understand the distribution, and
affect of hyperhidrosis in this part of world and to identify the
