Elevated thyroid TSH levels can often be cured. Elevated TSH is usually caused by factors such as hypothyroidism, iodine deficiency, pituitary lesions, drug effects, or subacute thyroiditis, and can be improved through drug replacement therapy, dietary adjustments, etiological treatment, and other methods.

1. Hypothyroidism:
Primary hypothyroidism is the most common cause of elevated TSH, and insufficient secretion of thyroid hormones leads to compensatory increase in TSH secretion by the pituitary gland. Clinical manifestations include fatigue, fear of cold, and weight gain. Long term replacement therapy with levothyroxine sodium is necessary, and TSH levels should be monitored regularly to adjust dosage.
2. Iodine deficiency:
Long term iodine deficiency in diet can lead to insufficient synthesis of thyroid hormones, causing endemic goiter with elevated TSH. By consuming iodine rich foods such as iodized salt and kelp, it can be corrected. In severe cases, thyroid hormone treatment should be combined, and the indicators can usually return to normal within 3-6 months.
3. Pituitary lesions:

Pituitary tumors or hypothalamic lesions may lead to abnormal increase in TSH secretion, often accompanied by symptoms such as headache and visual impairment. Diagnosis needs to be confirmed through MRI, and treatment mainly involves surgical resection or radiation therapy. After surgery, TSH levels in most patients can gradually recover.
4. Drug effects:
Lithium supplements, amiodarone, and other drugs can interfere with thyroid hormone synthesis, leading to secondary TSH elevation. After stopping or changing medication, the indicators can often recover on their own. If necessary, short-term supplementation of thyroid hormones can improve symptoms. 5. Subacute thyroiditis: In the early stages of thyroiditis caused by viral infection, transient TSH elevation may occur, accompanied by neck pain and fever. Normally, it takes 2-3 months for the patient to self heal. In the acute phase, nonsteroidal anti-inflammatory drugs can be used to treat the condition. In rare cases, permanent hypothyroidism may require lifelong medication.
It is necessary to ensure a daily intake of 150 micrograms of iodine, and consume foods rich in selenium and zinc such as seafood, eggs, and milk in moderation. Avoid excessive intake of thyroid enlargement causing substances such as cabbage and cassava. Regularly monitor TSH indicators and have thyroid function rechecked every 3-6 months during treatment. Moderate aerobic exercise such as brisk walking and yoga can help improve metabolism, but vigorous exercise should be avoided when hypothyroidism is not controlled. Maintaining sufficient sleep and emotional stability has a positive effect on the recovery of thyroid function.
