What is the reason for high thyroid function TSH

The thyroid gland is an organ that the human body pays special attention to. It is also a relatively fragile organ that is prone to some adverse problems. Therefore, people need to pay special attention to the examination of the thyroid gland. Many people will have high thyroid function TSH when undergoing thyroid examination. This situation is likely caused by hyperthyroidism. Let's take a detailed look at what is high thyroid function TSH?

TSH is thyroid stimulating hormone, a hormone secreted by the human pituitary gland that promotes the secretion of thyroid hormones. When TSH is elevated, the first thing to consider is whether there is hypothyroidism or subclinical hypothyroidism. Generally, when hypothyroidism or subclinical hypothyroidism occurs, the first symptom is an increase in TSH. Because the current TSH measurement is based on the sensitive method, changes in TSH will occur before changes in thyroid hormones. In addition, it is also necessary to consider whether there is a pituitary thyrotropin-stimulating hormone tumor, which causes the increase of TSH.

When a thyroid examination finds that TSH is too high, analyze from the following aspects: 1. If FT3 and FT4 are too high, consider pituitary hyperthyroidism and further check the pituitary; 2. If FT3 and FT4 are too low, consider hypothyroidism, and it is necessary to clarify whether it is transient hypothyroidism or permanent hypothyroidism to decide whether to treat it with Euthyrox; 3. For ordinary people, FT3 and FT4 are normal, and the TSH value is looked at. If it is greater than 10, treatment is required. If it is not more than 10, regular check-ups are recommended; 4. Before pregnancy or pregnant women, if FT3 and FT4 are normal and TSH is too high, combine TPOAb. If this antibody is positive, Euthyrox treatment is required. If the antibody is negative and not more than 10, no treatment is required.

High levels of TSH receptor antibodies are generally caused by a decline in thyroid function, which we often call hypothyroidism. Excessive secretion of thyroid hormones will cause this endocrine disease, and will also cause symptoms such as sexual dysfunction and hypoproteinemia, which are also the main factors for high levels of TSH receptor antibodies. On the contrary, if the TSH receptor antibody is low, it is often closely related to hyperthyroidism, which is mainly caused by excessive thyroid hormone in the human body, which will often make people excited and the body's metabolism is always in a hyperactive state. Clinically, painless thyroiditis with hyperthyroidism, thyrotoxicosis, etc. will lead to low TSH receptor antibodies.
