primary hyperhidrosis, quality of life, cholinergic dysregulation, treatment strategies, economic burden, diagnosis and managementAbstract
Primary hyperhidrosis is termed as excessive sweating exceeding the physiological needs of thermoregulation. This review provides an updated overview focusing on epidemiology, quality of life, pathophysiology, economic impacts, diagnostic approaches and current management strategies. A literature search was conducted in June 2026 across PubMed and the Cochrane Central Register of Controlled Trials. Additional references were identified through manual searches of relevant bibliographies. Reported prevalence of hyperhidrosis varied widely, likely reflecting differences in methodology and disease recognition. Primary hyperhidrosis is associated with autonomic dys-regulation involving sympathetic pathways. Emerging evidence suggests that molecular alterations in eccrine glands may represent secondary adap-tations to sustained cholinergic stimulation, while genetic variability in receptor expression may contribute to interindividual differences in disease severity. Hyperhidrosis has a strong negative impact on the economy and quality of life, adversely affecting both mental and physical health. Multiple treatment options are available, including topical therapies, systemic agents, device-based interventions, botulinum toxin injections, and surgery. Despite increasing recognition of the clinical burden, comprehensive economic evaluations remain limited, with indirect costs and long-term societal impact insufficiently characterized. In conclusion, primary hyperhidrosis imposes a substantial burden on affected individuals, requiring improved re-cognition, standardized diagnostic frameworks, and individualized management strategies supported by high-quality and longitudinal research.
