What is the reason for a sudden increase in TSH after a hemisection of the thyroid cancer?

Hemisection of thyroid cancer refers to a hemisection of thyroid cancer. If the TSH value suddenly increases after the surgery, it may be caused by surgical injury, excessive iodine intake, hypothyroidism, cancer cell metastasis, etc. Patients are advised to receive targeted treatment under the guidance of a doctor according to different causes.

1. Surgical injury: Thyroid cancer hemisection surgery usually involves removing the thyroid gland on one side of the patient. Since there is a recurrent laryngeal nerve around the thyroid gland, it may cause damage to the recurrent laryngeal nerve. Generally, the patient's TSH value will gradually return to normal within 3 months after surgery. If the patient's TSH value is still within the normal range 3 months after surgery, you need to be vigilant and perform a second surgery in time;

2. Excessive intake of iodine: Some patients may eat foods rich in iodine, such as kelp and seaweed, after undergoing hemisection of thyroid cancer. Since iodine promotes the secretion of thyroid hormones, patients may have excessive secretion of thyroid hormones. In this case, the patient's TSH value may suddenly increase. It is recommended that patients control their diet and reduce the intake of iodine-containing foods;

3. Hypothyroidism: After hemisection of the thyroid cancer, patients with thyroid cancer may suffer from hypothyroidism. The body cannot synthesize thyroxine, resulting in low thyroid hormone levels and a decrease in the TSH value secreted by the pituitary gland. In this case, patients can take levothyroxine sodium tablets, thyroid tablets and other drugs as prescribed by the doctor to achieve the purpose of increasing thyroid hormone levels;

4. Cancer cell metastasis: If the cancer cells are not removed in time after the patient undergoes hemisection of thyroid cancer, resulting in cancer cell metastasis, it may affect the function of the pituitary gland to secrete TSH, thereby causing an increase in TSH values. It is recommended that patients eliminate cancer cells through radiotherapy, chemotherapy, etc. under the guidance of a doctor.

It is recommended that patients should pay attention to rest after surgery, avoid staying up late and overwork, maintain a happy mood and stable emotions, and avoid excessive tension and stress.
