Patients with hypothyroidism usually do not sweat profusely. Hypothyroidism is characterized by a generalized hypometabolic syndrome, which may be characterized by decreased sympathetic excitability. The onset of hypothyroidism is relatively insidious, with a long course and a lack of specific symptoms. In mild cases, there may be no specific symptoms, and the more typical symptoms include chills, drowsiness, weakness, swelling of hands and feet, low sweating, memory loss, weight gain, constipation, etc. Female patients may have menstrual disorders or excessive menstruation, infertility and other manifestations. Because of the low metabolic symptoms, there is usually no profuse sweating. For patients with hypothyroidism who have excessive sweating, it is recommended that they seek medical attention as soon as possible after eliminating physiological factors such as heavy eating, strenuous exercise, etc., so as to avoid delays in diagnosis and treatment.
