Thyroid cancer stimulator TSH is low

Low thyroid cancer stimulating hormone TSH, i.e., low thyroid-stimulating hormone (TSH) levels, may be caused by primary hyperthyroidism, pituitary lesions, drug factors, etc. Patients are advised to seek medical attention in a timely manner and carry out targeted treatment under the guidance of a doctor.

1. Primary hyperthyroidism: mostly caused by excessive iodine intake or autoimmune abnormalities and other factors, which can lead to excessive proliferation of thyroid follicular epithelial cells, thereby secreting more thyroid hormones, at this time the body is in a state of high metabolism, which will appearpalpitation, sweating, weight loss and other symptoms.Such conditions can lead to a decrease in TSH, which generally requires treatment with drugs such as methimazole tablets as prescribed;

2. Pituitary lesions: such as pituitary tumors, when the tumor compresses the hypothalamus, it will affect the function of the hypothalamic-pituitary axis, and then affect the secretion of TSH. At this time, the patient may experience symptoms such as headache and vision loss, and it is recommended to treat it by surgical excision under the guidance of a doctor;

3. Drug factors: If you take drugs such as levothyroxine sodium tablets, it may lead to an increase in the level of thyroid hormone in the body, thereby inhibiting the secretion of TSH. At this time, patients may experience symptoms such as palpitation and hand tremors, and it is recommended to adjust the dosage or stop the drug under the guidance of a doctor.

In addition to the common causes mentioned above, it may also be associated with subacute thyroiditis. If the patient's symptoms persist or worsen, he or s should go to the endocrinology department of the hospital in time and complete the relevant tests to confirm the diagnosis.
