Hyperhidrosis Comorbidities and Treatments: A Register-based Study among 511 Subjects

Abstract

Hyperhidrosis is a dermatological condition that causes psychosocial impairment and has a negative impact on patients’ quality of life. The epidemiology of hyper-hidrosis is currently poorly understood. The aim of this study was to analyse comorbidities and treatments in 511 subjects with hyperhidrosis selected from the patient records of Oulu University Hospital. The mean age of patients with local hyperhidrosis was 27.9 years and the majority were female (62.7%). The most common anatomical site of symptoms in the youngest age group was the palms, whereas the axillae were a more common site in advanced age. Depression was a common comorbidity in both local (11.6%) and generalized hyperhidrosis (28.6%). Anxiety affected 12.7% of patients with generalized hyperhidrosis. In 36.8% of the patients with local hyperhidrosis there was a delay in diagnosis of more than 10 years. The most common-ly used treatments included topical antiperspirants, iontophoresis and botulin toxin injections.
