What does it mean when TG is elevated after hemisection of thyroid cancer

The elevated TSH level after hemisection of thyroid cancer means that the thyroid has been hemisectioned and the postoperative pathological results indicate thyroid cancer metastasis. This may be caused by excessive thyroid hormone intake after surgery or residual lesions after surgery. It may also be caused by TSH suppression therapy and other reasons.

1. Excessive intake of thyroid hormone after surgery: After hemisection surgery, some patients with thyroid cancer need to take thyroid hormone to maintain the body's normal physiological functions. If patients take excessive thyroid hormone after surgery, it will cause endocrine disorders, leading to elevated TSH. At this time, you should follow the doctor's advice to adjust the drug dosage in time, and pay attention to keeping a light diet;

2. Postoperative residual lesions: After a hemisection of a thyroid cancer patient, if the lesions are not completely removed and a small amount of lesions remain in the thyroid bed, it will stimulate the body to produce elevated TSH. It is recommended that the patient undergo a secondary surgery in a timely manner, or remove the residual lesions under ultrasound guidance;

3. TSH suppression therapy: After hemisection surgery, some patients with thyroid cancer also need iodine-131 treatment or ultrasound interventional therapy, which mainly uses the beta rays released by iodine-131 to enter the thyroid tissue and release rays, thereby damaging the thyroid tissue and reducing the secretion of thyroid-stimulating hormone in the patient's body, thereby causing an increase in TSH. During the treatment, thyroid function, liver function, and blood routine tests should be monitored regularly;

4. Other reasons: If the patient is pregnant or taking estrogen drugs, it may cause an increase in TSH. Pregnant women can take drugs such as levothyroxine sodium tablets as prescribed by the doctor. Estrogen drugs will affect the secretion of thyroid hormone and may also cause an increase in TSH. Generally, it can return to normal after stopping the medication.
