The easiest way to recognize if you are suffering from hyperthyroidism is to look for symptoms of high metabolism, such as palpitations, hand tremors, irritability, excessive sweating, weight loss, and hyperphagia, etc. It is recommended to diagnose the disease under the guidance of a doctor. Hyperthyroidism is a series of hypermetabolic syndromes caused by excessive production of thyroid hormones by the thyroid gland itself. Patients may often experience agitation, irritability, tachycardia, fear of heat, excessive sweating, weight loss, increased appetite, and increased frequency of bowel movements or diarrhea. It may also be accompanied by proptosis, pre-tibial mucous edema, etc. Women may have menstrual cycle disorders and other manifestations. Besides judging by clinical symptoms, the most direct and accurate way is to go to the endocrinology department for thyroid function and thyroid ultrasound and other tests to make a clear diagnosis.
