Thyroid and Pregnancy
The thyroid gland is under stress and strain from pregnancy alone, it has to work about half again as hard to produce the hormones to keep up with the demand of pregnancy, so it is very important for a pregnant patient. As for background information your thyroid gland runs your metabolism, and it is subject to stresses from environmental factors, genetic predisposition and even viral infections. Thyroid function also directly and indirectly affects whether you get pregnant and how healthy that pregnancy is. To accommodate the need for extra thyroid hormone in pregnancy the thyroid gland enlarges but it shouldn't take on actual nodules. Higher miscarriage rates, more frequent preterm deliveries, increased risk of high blood pressure, more patients becoming diabetic and having diabetic complications, higher risk for placental problems like premature separation, and adverse fetal effects have all been reported with thyroid disease when you are pregnant! In women with thyroid disease at least half of implanted embryos will not survive to delivery,with most of these pregnancy losses occur in the first trimester.Although there are many contributing factors both having high and low thyroid tests are actually associated with miscarriages.
