The thyroid is the gland that produces hormones called thyroxine, which regulate metabolism. The most common hyperthyroidism diagnoses are Graves’ disease and Hashimoto’s thyroiditis (also known as chronic autoimmune thyroiditis or chronic lymphocytic hypothyroidism). Both conditions can cause excessive sweating at night for men.
However, other causes can also result in this condition including: pituitary tumors; diabetes mellitus; Cushing disease (a rare disorder caused by excess cortisol); or adrenal gland disorders such as Addison’s disease. If you think your sweat production might be excessive due to another diagnosis, it’s important to see a doctor immediately. Excessive sweating could be a sign of serious underlying illness that requires immediate treatment with medication — not just deodorant!
