Self-Reported Prevalence and Awareness of Hyperhidrosis Among Medical Students at the Gulf Medical University, UAE

Introduction Hyperhidrosis is a condition characterized by excessive sweating that can negatively affect quality of life and psychosocial well-being. This study aimed to determine the self-reported prevalence of hyperhidrosis symptoms and the level of awareness among medical students at Gulf Medical University, Ajman, UAE. Methods A cross-sectional study was conducted over six months among students aged ≥18 years across six academic programs. Ethical approval was obtained, and a pilot study was conducted before data collection. A structured self-administered questionnaire developed from a literature review and reviewed by specialists was used to assess sociodemographic characteristics, self-reported excessive sweating symptoms suggestive of hyperhidrosis, awareness, and associated factors. Data were analyzed using descriptive and inferential statistics. Results Out of 600 eligible participants, 480 completed the questionnaire (response rate: 80%). The majority were female (75.4%) and aged 18-21 years. The prevalence of self-reported excessive sweating symptoms suggestive of hyperhidrosis was 36.8% (171/465; 95% CI: 32.4%-41.2%). Among participants reporting excessive sweating symptoms who responded to the relevant items, the axilla was the most commonly affected site, followed by the face and hands. Afternoon was the most frequently reported time of excessive sweating. Awareness of hyperhidrosis was low, with only 31.7% of participants reporting prior knowledge, most commonly through the internet and academic sources. A significantly higher prevalence of self-reported excessive sweating symptoms was observed among males compared to females (p<0.01). Smoking was also significantly associated with self-reported excessive sweating symptoms (p<0.05). No significant associations were observed with age group, body mass index, or diabetes status. A proportion of participants reported a positive family history of similar symptoms. Conclusion Self-reported excessive sweating symptoms suggestive of hyperhidrosis were relatively common among medical students, but awareness remained low. While associations with gender and smoking were observed, the findings should be interpreted cautiously, given the use of self-reported data rather than clinically validated diagnostic criteria. Increased awareness and further studies using validated diagnostic instruments are recommended.
