Hypothyroidism During Pregnancy

Every woman planning to get pregnant, should get their thyroid tested pre-conception and then again as soon as possible in their first trimester of pregnancy. In early pregnancy the fetus is dependent on the mother to supply the thyroid hormones essential for brain development. If the mother is hypothyroid, she may not be able to supply her fetus with enough thyroid hormones, putting the fetus at risk. Thyroid levels change quickly in pregnancy, so do not delay.

Hypothyroidism During Pregnancy

What is Thyroid?

The thyroid gland is sited somewhere in the lower neck area in front. It is a major constituent of the endocrine system, known for the release and storage of hormones that trigger cellular actions.

The thyroid gland is made of the two most crucial hormones Thyroxin and Triodothyronine. Your metabolism and energy processing depends entirely on these two. Although marginally, thyroid can affect your ability in ovulating, thus giving you a hard time in conceiving. It might so be that you either produce too much of the thyroid hormone, a condition known as hyperthyroidism or maybe a little too less, leading to hypothyroidism. Needless to say, it affects your chances of getting pregnant too.

The ultimate aim of hypothyroidism is to keep the thyroid hormone level within the normal range.

Not enough production of the thyroid hormones can lead to hypothyroidism. This is usually triggered when there is a significant deficiency in iodine. The signs and symptoms include infertility, irregular menstrual cycle, galactorrhea (a condition where there is milk flow even without childbirth). Low basal body temperature is also a deciding factor.

These conditions if left untreated can cause difficult in your pregnancy and give rise to other complications as well. Some of them are anemia, miscarriage and placental detachment. Postpartum hemorrhage is a common phenomenon as well. The baby even if he overcomes these difficulties might suffer from low birth weight issues and thyroid problems from the very birth itself. Birth defects are common as well. The final type of thyroid is the Hashimoto’s thyroiditis.
