Understanding Secondary Hyperhidrosis: Causes and Treatments

Secondary hyperhidrosis occurs when excessive sweating is linked to an underlying medical condition. Unlike primary hyperhidrosis, which is usually localized, secondary sweating affects the entire body and is often not present during sleep. It’s often a symptom of other health issues such as hormonal imbalances, medications, or chronic diseases like diabetes or thyroid disorders.

Diagnosis
Identifying the cause involves medical evaluation and tests. Notable reasons include pregnancy, menopause, obesity, Parkinson's disease, or lymphoma. Prompt diagnosis helps target treatment effectively.

Understanding Secondary Hyperhidrosis
The primary goal of treatment is to address the underlying condition and reduce symptoms. Over-the-counter antiperspirants with aluminum chloride may provide relief, with stronger options prescribed if necessary. Advanced procedures, such as Botox injections, microwave therapy, or laser treatments, are available mainly for underarm hyperhidrosis. In severe cases, surgical intervention like thoracic sympathectomy may be considered, but only after thorough consultation with healthcare professionals.
