If you're sweating more than usual, or at unusual times, visit your doctor to make sure that it's not caused by an underlying illness or medical condition that should be treated. Excessive sweating is a symptom of various health problems, including heart disease, hyperthyroidism, hypoglycemia, leukemia, menopause, non-Hodgkin's lymphoma, tuberculosis and several stress and anxiety disorders. Certain medications like beta blockers and tricyclic antidepressants can also cause excessive sweating.
