What does low TSH mean in pregnant women?

The physical and mental health during pregnancy and the growth and development of the fetus are very important issues. Pregnant women do not need to deliberately skip all prenatal examination items. Some standard values ​​in the items can directly reflect the physical and mental health of the pregnant mother and the fetus. If the standard value shows that there is a problem, the hospital can intervene immediately to minimize the damage caused by the problem. So what should pregnant women do if their TSH value is low? What does low TSH mean for pregnant women?

What does low TSH mean for pregnant women?

If a pregnant woman only has a slightly low TSH level, but normal T3 and T4, and has no clinical symptoms of thyroid disease, it may be a subclinical hyperthyroidism, which generally will not have any significant effects on the fetus, and no medication is needed.

During pregnancy, a significant increase in hCG gonadotropin can affect TSH metabolism. Women with severe vomiting during pregnancy will also have their TSH levels affected. In the early stages of pregnancy, about 15% of normal pregnant women will have TSH levels significantly lower than normal. In the second and third trimesters, some women will have TSH levels significantly lower than normal, which may be mainly affected by HCG.

If the TSH level is much lower than the standard value, it is necessary to check the thyroid color ultrasound and other related tests such as growth hormone and thyroid cyst antigen to understand the problem of thyroid cyst.

What should I do if my pregnant woman has a low TSH value?

During pregnancy, the body of pregnant women is affected by estrogen and oestrogen, and many unique symptoms will appear, which is a relatively normal phenomenon. Because pregnancy is a special physiological stage, the thyroid hormone level in pregnant women will undergo certain changes at this time, and the TSH standard value will be lower than when they are not pregnant. Pregnant women do not need to worry too much.

During a woman's entire pregnancy, the body's TSH will be slightly lower than usual, but there will also be a normal range. If it is significantly lower, you must communicate with your doctor in time to see if the increased TSH value will affect the health and growth of the fetus. The doctor will give the appropriate treatment method based on the test results.

Each prenatal checkup has a certain function. The doctor will judge the pregnancy status based on these index values ​​and give pregnant women more beneficial advice on pregnancy. Pregnant women should follow the doctor's instructions, eat properly, maintain a stable mental state, and keep themselves in good condition during pregnancy.
