Low thyroid stimulating hormone and high antithyroglobulin may be caused by a variety of reasons, such as Hashimoto’s hyperthyroidism, Graves’ disease, etc. The results alone cannot confirm the diagnosis, but should be combined with other test results to clarify the disease, and the treatment of different diseases is different. 1. Hashimoto’s hyperthyroidism: Hashimoto’s thyroiditis hyperthyroidism is mostly transient, the degree is usually mild, so patients in the hyperthyroidism stage are usually not treated with antithyroid medication, and β-blockers can be used to alleviate the symptoms of hyperthyroidism, such as palpitations, trembling hands and sweating. 2. Graves’ disease: patients need to follow the doctor’s instructions to take anti-thyroid drugs, such as methimazole and propylthiouracil, but also radioactive iodine treatment and surgical treatment. It is recommended to consult a doctor in time to choose the appropriate treatment plan after comprehensive assessment of the condition.
