Hyperhidrosis Heredity Survey
It has been demonstrated that 5% of the population carry a gene for hyperhidrosis. More recently a genetically regulated water or sweat channel protein has been found in greater number or overexpressed in individuals with hyperhidrosis. As such, we thought a survey exploring hyperhidrosis and family heredity would
provide further insight and additional perspective. Keep in mind that these results are of those responders that have identified family links of their own and are not representative of all individuals with hyperhidrosis.
When asked to respond about which family member was also affected with hyperhidrosis, our sample responded as follows:
* Data based on anonymously gathered results from the Dry Pharmacist's Hyperhidrosis Heredity Survey. Reproduction or use of these data is strictly prohibited without written consent from the Dry Pharmacist.
Direct Family Relatives
Few (only 12%) answered this part of the survey. We suspect that many of our respondents were unaware whether hyperhidrosis also affected direct family members from older generations. Of those that answered, 50% mentioned that their grandmother had hyperhidrosis. A third mentioned their grandfather and 16% their great grandmother. It should be noted we do not have much faith in these numbers as the responding sample was very small.
Indirect Family Relatives
A significantly greater number (33%) answered this part of the survey. While aunts and uncles were mentioned as 33% and 22% also having hyperhidrosis respectively, cousin mentions far outnumbered those associated the latter relatives. The cousin group was mentioned by almost 70% of respondents.
A Few Final Words
While it is difficult to draw definitive conclusions or correlations based on these data we believe that these survey results certainly support studies that propose that focal hyperhidrosis is inherited in many individuals.
Of course comments and observations are always welcome. We promise to respond and may anonymously post some of these on our Sweating Matters blog.
