People with hyperhidrosis — an excessive sweating condition — also seem to have higher-than-average rates of anxiety and depression, a new study suggests.

Roughly 21 percent and 27 percent of people with hyperhidrosis screened positive for anxiety or depression, respectively. That compared with 7.5 percent and just under 10 percent of other patients, the study revealed.

The findings do not prove that hyperhidrosis caused those mental health issues. In some cases, excessive sweating may be part of an anxiety disorder, for example.

“It’s not clear if this is cause-and-effect,” said Dr. Dee Glaser, a professor of dermatology at Saint Louis University School of Medicine.
