Plantar Hyperhidrosis: An Overview.

Plantar hyperhidrosis, excessive sweating on the soles of feet, can have a significant impact on patients' quality of life and emotional well-being. Hyperhidrosis is divided into primary and secondary categories, depending on the cause of the sweating, with plantar hyperhidrosis typically being primary and idiopathic. There is an overall increased risk of cutaneous infection in the presence of hyperhidrosis, including fungal, bacterial, and viral infections. This article discusses a range of treatment options including topical aluminum chloride, iontophoresis, injectable botulinum toxin A, glycopyrrolate, oxybutynin, laser, and endoscopic lumbar sympathectomy. Lifestyle changes regarding hygiene, shoe gear, insoles, and socks are also discussed.
