The reason for the wasting of the body is not caused by thyroid nodules, but mainly includes the following: 1. Consider that the body is wasted due to hyperthyroidism, resulting in metabolic dysfunction of the body. 2. Consider that the body is wasted due to diabetes, resulting in eating more, drinking more, drinking more and urinating more, which will be accompanied by wasting. Thyroid nodules are a common clinical disease in thyroid surgery. The typical symptom is a lump in the thyroid gland, which is usually found by unintentional physical examination, ultrasound of the thyroid gland, or CT examination of the thyroid gland. If the thyroid nodule is more than 1cm, surgery is recommended. If the thyroid nodule and thyroid function are normal, the person will not lose weight. If the thyroid nodules and thyroid function are normal, the person will not lose weight, but after the person loses weight, he/she needs to go to the hospital. Blood tests such as blood glucose, liver function, kidney function and urine routine are taken on an empty stomach to clarify the causes of hyperthyroidism or elevated blood glucose through laboratory tests.
