Generalised Hyperhidrosis
Generalised hyperhidrosis is a condition characterised by excessive sweating across the entire body. It is classified into two types – primary (idiopathic) hyperhidrosis, where the cause is unknown, and secondary hyperhidrosis, which is due to underlying medical conditions such as thyroid disorders, diabetes, menopause, carcinoid syndrome, pheochromocytoma and other malignancies. This condition can lead to significant discomfort, affecting both social and psychological well-being, and poses challenges in daily life.

Treatment Options for Generalised Hyperhidrosis
The treatment of generalised hyperhidrosis focuses on investigating potential medical causes and managing the symptoms in cases of primary hyperhidrosis. Oral medications, specifically anticholinergics, are used to reduce sweating across the body. However, topical treatments often have limited effectiveness for generalised symptoms due to the widespread nature of the condition. Identifying and treating any underlying conditions is crucial for individuals with secondary hyperhidrosis, as it addresses the cause of the excessive sweating. Lifestyle adjustments, such as wearing breathable clothing and using absorbent materials, can also aid in managing the symptoms.
