TSH refers to thyrotropin hormone, and the value of thyrotropin hormone is unstable after thyroid hemisection. If the patient experiences an increase in TSH, he or she needs to be treated with medication as prescribed by the doctor. If the patient experiences a decrease in TSH, the medication needs to be discontinued. If TSH appears to be increased after thyroid hemisection, which indicates that the thyroid gland does not secrete enough thyroxine, then medications to promote thyroid hormone secretion, such as levothyroxine sodium tablets and thyroxine tablets, need to be used under the direction of the doctor. If the TSH test is below normal, it means that the level of thyroxine in the blood is higher than normal, inhibiting the secretion of TSH. In this case, you need to reduce the dosage of levothyroxine sodium tablets, thyroxine tablets. It is recommended that patients should be tested regularly for TSH, T3, T4 and other relevant thyroid hormones to guide the adjustment of the dosage of Levothyroxine Sodium Tablets, Thyroxine Tablets after thyroid hemisection.
