Low FT3 in pregnant women

Low FT3 in pregnant women

Pregnant women are very concerned about their own safety. If they find that their ft4 is low during prenatal check-up, they will be very worried about whether the fetus in their belly will be affected. The most important thing in this case is to stay calm and not panic too much, otherwise the condition will fluctuate more. If necessary, some drugs can be used to regulate the changes in the condition in your body.

Patients with hypothyroidism can become pregnant, and they must not stop taking medication during pregnancy. Not only must they not stop taking medication, but they also need to increase the dosage of levothyroxine sodium to keep the TSH index at the lower limit of normal values. Otherwise, it will lead to mental retardation in children and other adverse conditions.

Therefore, you must take medication under the guidance of a doctor during pregnancy. As long as the "thyroid function" index is controlled within the appropriate range, it is completely possible to become pregnant and have a child, so there is no need to worry.

Levothyroxine sodium is levothyroxine, a hormone essential to the human body.

Patients with hypothyroidism have thyroid disease that prevents them from secreting this hormone. As a result, they will experience symptoms such as fear of cold, fatigue, rough skin, dry stools, and irregular menstruation. Therefore, they need to supplement this hormone exogenously to maintain normal physiological functions.

The dosage of medicine required by the patient is regulated according to the test indicators of his "thyroid function". It cannot be determined based on the patient's self-feeling or the doctor's clinical experience. The "thyroid function" must be tested regularly to know whether the dosage of medicine is appropriate.

1. Patients with hypothyroidism should consider pregnancy only after their thyroid function (FT3, FT4, TSH) returns to normal. It should be emphasized that due to the physiological changes during pregnancy, the reference value range of thyroid function indicators during pregnancy changes, and a pregnancy-specific reference value range needs to be adopted. The normal range of serum TSH in the general population is 0.3~5.0mU/L, while TSH during pregnancy should be controlled below 2.5mU/L, and FT4 should be maintained in the upper 1/3 of the normal range for non-pregnant women.

2. Medication for the treatment of hypothyroidism cannot be discontinued. Some patients with hypothyroidism stop taking thyroid hormones without authorization after becoming pregnant because they are worried that it will have adverse effects on the fetus. This is very wrong. Thyroid hormone is a physiological hormone essential to the human body and is crucial to the development of the fetal brain and bones. Once it is deficient, it may cause "cretinism" in offspring. As long as the replacement dosage is appropriate, there will be no adverse effects on the human body.
