Endocrinopathies are an important cause of secondary hyperhidrosis and should always be remembered in the differential diagnosis of excessive sweating. The most common endocrine cause of hyperhidrosis is the physiological decrease in the production of sex hormones in menopause and, very rarely, in its male counterpart, the “andropause”. Among the pathological endocrine causes of hyperhidrosis we highlight hyperthyroidism, pheochromocytoma, hypoglycemia, acromegaly, and carcinoid syndrome.
