Introduction to the hazards of low thyroid stimulating hormone in pregnant women

Let me introduce to you the dangers of low thyroid stimulating hormone in pregnant women. Iodine is an indispensable trace element for the human body and is the basic raw material for the thyroid gland to synthesize thyroid hormones. Thyroid hormones not only play an important role in the growth and development of the human body, but also play an important role in the brain development of children. Let me introduce it to you below.

First, hypothyroidism can be inherited, and pregnant women can also suffer from hypothyroidism. It may affect the child's intellectual development. It is recommended to take the child to the hospital for examination and be sure to explain the pregnancy situation to the doctor.

Second, no matter hyperthyroidism, hypothyroidism or low thyroid, mild cases will not affect pregnancy, but the miscarriage or stillbirth rate is high. Severe cases may cause loss of libido, impotence, decreased sperm count and infertility in male patients, and excessive and frequent menstruation in female patients with low thyroid. If not treated, it may also lead to infertility. If a pregnant woman has hypothyroidism (hypothyroidism, low thyroidism) or hypothyroidism, the impact on the fetus is greater than that of hyperthyroidism, and the miscarriage rate and perinatal mortality rate of the fetus increase.

Third, autoimmune diseases such as hyperthyroidism or Hashimoto's disease may be inherited, but most people will give birth to a healthy child. Now there will be thyroid disease screening after childbirth. Even if there is a disease, if it can be discovered in time, the child can receive timely treatment. Good.

Fourth, the first three months of pregnancy is the key development stage of the fetal eyeball and subretinal cavity. Since the thyroid function of the fetus is not formed until the third month of embryonic development, the mother provides thyroid hormones during this period. The placenta during pregnancy already has dehydrogenase activity, and the mother's thyroid hormones can basically not enter the placenta. The fetus uses iodine to synthesize thyroid hormones. When the mother is iodine deficient, the pituitary gland in the mother's brain can secrete a substance called TSH, which can prompt the mother's thyroid gland to better capture iodine. To provide for the synthesis of thyroid. Especially when the mother's thyroid is insufficient and causes goiter, less iodine is given to the fetus at this time, resulting in a decrease in the thyroid hormone synthesized by the fetus. This period is a critical period for the development of the fetal cerebral cortex, basal ganglia and inner ear structure. Clinical observations show that mental retardation and deafness are common in patients with cretinism. Mild damage to the nervous system manifests as psychomotor dysfunction. Epidemiological surveys show that the degree of damage to psychomotor dysfunction caused by iodine deficiency is significantly greater than that caused by non-iodine deficiency factors.

Thyroid hormone has irreplaceable physiological functions. When thyroid hormone synthesis is insufficient, the mother may suffer from goiter. More importantly, it will affect the development of the fetus's brain and inner ear structure and neuromotor function. Therefore, when pregnant women are iodine-deficient, they should be very careful not to be iodine-deficient and should consume sufficient amounts of iodine. It is recommended to go to a regular hospital for a thorough examination and cooperate with the doctor's treatment according to their actual situation. Do not waste time and cause fetal maldevelopment. I wish you a speedy recovery and a healthy baby.
