The normal value of thyrotropin is between 0.35 and 5.5 μIU/ml, and 11.5 mU/L is considered elevated. Whether thyrotropin 11.5mU/L is serious or not should be analyzed according to the specific situation. If the patient is in the recovery period of subacute thyroiditis, the value will return to normal after complete recovery, and this situation is generally not serious. If the patient has primary hypothyroidism, Hashimoto’s thyroiditis, pituitary hypothyroidism and other diseases, these diseases will lead to hypothyroidism and cause an increase in thyrotropin. If left untreated, it may lead to mucous edema coma, which can be life-threatening in severe cases. Thyroid-stimulating hormone 11.5 mU/L should be treated on a case-by-case basis by seeking prompt medical attention to identify the cause.
