Low thyroid in pregnant women

The hormone secretion of pregnant women is in a disordered state, mainly because the estrogen secretion of women during pregnancy is very strong, which will lead to an imbalance in internal hormone secretion. It is normal for some hormones to be in a low state when they are not stable during pregnancy. In most cases, pregnant women's thyroid-stimulating hormone levels are low in the early stages of pregnancy. People who have undergone prenatal checkups will understand this, but in the middle and late stages of pregnancy, hormone levels will gradually return to normal.

What causes low thyroid stimulating hormone during pregnancy?

Human chorionic gonadotropin (hCG) is an important hormone during pregnancy. Expectant mothers who have undergone prenatal checkups must be familiar with this hormone. What you may not be familiar with is that in addition to being very important to the pregnancy process itself, this hormone also has a function similar to stimulating thyroid activity.

Therefore, when the hCG level in the blood rises sharply in the early pregnancy, the thyroid activity also increases accordingly, and the thyroid hormone level in the pregnant woman also tends to increase. At this time, the body will use the "negative feedback" mechanism of thyroid hormone to slightly reduce the content of thyroid stimulating hormone (TSH) in the blood, thereby maintaining the balance of thyroid hormone levels in the body. Generally speaking, the TSH level in the body may be slightly low in the early stages of pregnancy, but will gradually return to normal in the second and third trimesters.

What are the dietary precautions for low thyroid stimulating hormone?

1. Avoid iodine-containing foods and drugs: Iodine is the raw material for synthesizing thyroid hormones and can induce hyperthyroidism. Foods high in iodine should be avoided, such as kelp, laver, marine fish, seahorse, sea cucumber, dried shrimp, hair algae, etc. Various iodine-containing contrast agents should also be used with caution.

2. To increase the calorie supply, sufficient carbohydrates should be provided. Limit dietary fiber, enhance gastrointestinal motility, and limit high-fiber diets.

3. Ensure protein supply. Animal protein has a stimulating effect and should be eaten less. Mainly composed of plant proteins such as soybeans. Meat, eggs and milk options include pork, beef, goose, rabbit, duck, fish, milk, eggs, etc.

4. Increase the supply of vitamins: Patients with hyperthyroidism should choose foods rich in vitamin B1, B2 and vitamin C, eat animal offal appropriately, eat more fresh green leafy vegetables, and supplement with vitamin preparations if necessary.
