Thyroid Disease in Pregnancy | Dr Rama Sofat Hospital
Thyroid hormones are necessary for normal fetal development during the first 3 months. Because hypothyroidism and hyperthyroidism are possible, thyroid levels should be monitored before and throughout your pregnancy as explained by Dr Rama Sofat (IVF Expert)
The thyroid diseases—hyperthyroidism and hypothyroidism—are relatively common in pregnancy and important to treat. The thyroid is an organ located in the front of your neck that releases hormones that regulate your metabolism (the way your body uses energy), heart and nervous system, weight, body temperature, and many other processes in the body.
Thyroid hormones are particularly necessary to assure healthy fetal development of the brain and nervous system during the first three months of your pregnancy since the baby depends on your hormones, which are delivered through the placenta. At around 12 weeks, the thyroid gland in the fetus will begin to produce its own thyroid hormones as described by Dr Rama Sofat (IVF Expert).
There are 2 pregnancy-related hormones: estrogen and human chorionic gonadotropin (hCG) that may cause your thyroid levels to rise. This may make it a bit harder to diagnose thyroid diseases that develop during pregnancy.
However, if you have pre-existing hyperthyroidism or hypothyroidism, you should expect more medical attention to keep these conditions in control while you are pregnant, especially for the first trimester.
Occasionally, pregnancy may cause symptoms similar to hyperthyroidism; should you experience any uncomfortable or new symptoms, including palpitations, weight loss.
Untreated thyroid diseases during pregnancy may lead to premature birth, preeclampsia (a severe increase in blood pressure), miscarriage, and low birth weight among other problems. Therefore, it is important to talk to your doctor if you have had a history of hypothyroidism or hyperthyroidism so you can be monitored before and during your pregnancy, and to be sure that your medication is properly adjusted, if necessary.
Hyperthyroidism
Symptoms of hyperthyroidism may mimic those of normal pregnancy, such as an increased heart rate, sensitivity to hot temperatures, and fatigue. Other symptoms of hyperthyroidism include the following:
Causes of Thyroid Disease in Pregnancy
Hyperthyroid disease—The most common cause of maternal hyperthyroidism during pregnancy is the autoimmune disorder Grave’s disease. In this disorder, the body makes an antibody (a protein produced by the body when it thinks a virus or bacteria is present) called thyroid-stimulating immunoglobulin (TSI) that causes the thyroid to overreact and make too much thyroid hormone.
Hypothyroid disease—The most common cause of hypothyroidism is the autoimmune disorder known as Hashimoto’s thyroiditis. In this condition, the body mistakenly attacks the cells of the thyroid gland, leaving the thyroid without enough cells and enzymes to make enough thyroid hormone to meet the body's needs.
