What is hypothyroidism?

When your thyroid glands do not produce sufficient hormones it causes hypothyroidism.  The hormones released from the thyroid gland travel to every part of the body through blood.  This hormone regulates the absorption of energy from food by the cells of the body. When the thyroid gland does not produce sufficient hormones, there is not enough energy absorbed by the cells from the food you eat. As a result, your body becomes sluggish and weak.

Pregnancy can sometimes cause inflammation of the thyroid gland. This induces hypothyroidism. Women who have a history of thyroid disorders in their family are also susceptible to under active thyroid during pregnancy.Active Thyroid

Risks

Here are some of the risks of under active thyroid during pregnancy.

  • Under active thyroid during pregnancy can be fatal for the fetus. During the first trimester of your pregnancy, your baby receives the thyroid hormones from your body. If you have hypothyroidism, the fetus will not be able to get sufficient thyroid hormone. This will negatively impact the development of the baby’s brain functions. Thyroid hormones are necessary for proper functioning of the brain. Lack of this hormone will have long lasting effect on the baby.
  • Hypothyroidism is a potential cause of miscarriage. The lack of thyroid hormone will cause slow metabolism. A weak body might not be able to carry the pregnancy to its full term. This will lead to miscarriage.
  • Stillbirth is another fatal consequence of hypothyroidism during pregnancy. If your body does not absorb energy from the food, it cannot provide sufficient energy and nourishment to the baby. Lack of nourishment can cause stillbirth of the baby.
  • Hypothyroidism can also cause premature delivery. Insufficient thyroid hormone can lead to rupture of the membranes. This results in unexpected miscarriage. It is one of the significant risks of having under active thyroid during pregnancy.
  • When your body is unable to derive energy from the food, it cannot transfer energy to the fetus. Your baby derives nourishment and energy from your body. Hypothyroidism affects your metabolism. As a result, your baby is likely to have very low weight after birth. This can have lasting impacts on the overall health of your baby.
  • Untreated hypothyroidism can cause preeclampsia. This is a severe condition where the baby develops high blood pressure. This can damage the organs of his body. It can cause stillbirth as well. Preeclampsia can be equally harmful for you.
  • If you have hypothyroidism, it is likely to cause severe anemia. Slow metabolism can increase the number of unhealthy blood cells in your body. It also hampers the production of red blood cells. Lack of red blood cells will disrupt the passage of oxygen and other nutrients to your body tissues and the fetus. Severe anemia is a threat to you and your baby.
