TSH is usually elevated after thyroid hemicolectomy.
The thyroid gland is an important organ in controlling the normal metabolism of the body. Thyroid hormones have the important functions of increasing the basal metabolic rate, promoting glucose absorption, utilization, and lipid metabolism.
When a portion of tissue is surgically removed for thyroid disease, insufficient synthesis and secretion by the thyroid gland causes the pituitary gland, the upper level of the thyroid system, to release more TSH, or thyroid stimulating hormone, to promote hormone synthesis and secretion.
Generally, after thyroid hemicolectomy, thyroid hormone deficiency usually occurs for a certain period of time, which is what we usually call hypothyroidism, and it is necessary to temporarily and routinely take oral levothyroxine sodium tablets to supplement the exogenous thyroid hormone, to maintain the normal metabolism of the organism.
During the medication period, thyroid function should be monitored regularly, and the dosage should be adjusted by the level of thyroid hormones, such as TSH, FT4, FT3, and so on.
After thyroid surgery, it is important to monitor thyroid function dynamically and adjust the dose of medication under the guidance of endocrinologist.
