Hyperthyroidism And Pregnancy

In the course of your pregnancy, the chorionic gonadotropin hormone of the humans is produced. It has easy repercussions, and may cause few hyperthyroidism symptoms. This hormone can cause nausea in the course of the first trimester of pregnancy.

In cases of more pregnancies like twins, triplets, the levels of the HCG can become bigger, and the symptoms are more increased. 10-20% of pregnant women in this period can experience a provisory subclinical hyperthyroidism, but these pregnant women usually do not need any medicines.

There are also other rare affections in combination with abnormal pregnancies that can cause a hyperthyroidism. The pregnancies which are complicated by the hyperthyroidism can be the cause of bigger conditions such as:

  • Instant abortion
  • Preterm labor
  • Birth to death children
  • Birth to babies very low in weight
  • Pregnancy complications like pre eclampsia which is an affection almost the same as hypertension, urine with protein and mental disturbances and even heart affections.

Even though any type of hyperthyroidism can result in pregnancy complications, the most usual type is Graves’ illness.

There will be necessary medicines to slowing the woman’s heart course. The drugs that are recommended are the beta blockers. Even though these medicines are not dangerous for the baby, some specialists are saying that these medications are associated with retardation.

The operation can also have as a bad effect the premature pregnancy and instant abortion.

About 1% of the newborns from women who suffer of Graves’ illness, will experience hyperthyroidism when they are born. The cause of hyperthyroidism at birth is the antibodies transference that is stimulating the TSH to the newborn. These antibodies incite the thyroid gland of the baby. These antibodies must be controlled in the mother in the course of the second pregnancy trimester, due to the fact that the values that are bigger than the normal ones result in child hyperthyroidism at birth. The hyperthyroidism can be detected at birth with the help of a test of blood. At the physical examination, a low weight, an increased liver and spleen, and strange shapes of the head may lead to hyperthyroidism at birth.

The women who suffer of hyperthyroidism who want to nurse their babies should be able to safely nurse their child. Even though the older literature discouraged breastfeeding, new studies indicated that it is safe since the concentration of drug that enters the breast milk is low.
