Hypothyroidism indicators here may refer to the fact that thyroid stimulating hormone 64mU/L is hypothyroidism, which is something that needs to be treated. Normal thyroid stimulating hormone is in the range of 0.35 to 5.5mU/L, and 64mU/L is much higher than normal. Hypothyroidism is caused by insufficient production of thyroid hormone in the body of hypothyroid patients, or low utilization of thyroid hormone by the body, which results in the thyroid gland not being able to function as it should, resulting in hypothyroidism. Therefore, patients with hypothyroidism need exogenous thyroid hormone supplementation to ensure that the level of thyroid hormone in the body is maintained in the normal range and that the thyroid gland can function normally. Therefore, patients with hypothyroidism must be treated with lifelong medication, and once the medication is discontinued, the symptoms of hypothyroidism are very likely to reappear. In order to ensure the efficacy of the medication, patients with hypothyroidism also need to review the thyroid function every six months to a year, and adjust the dosage of the medication according to the condition under the advice of a professional doctor.
