Thyroid and Pregnancy

Thyroid glands are very important for a pregnant patient. We know that for background information your thyroid gland runs your metabolism. Thyroid function also directly and indirectly affects  whether you get pregnant and how healthy that pregnancy is.  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 dissociated with miscarriages.

Hypo- and hyperthyroidism are both associated with increased pregnancy loss. If a patient has an autoimmune problem with her pregnancy then she's also more likely to miscarry.  Women
are more likely than men to have antibodies against the thyroid, and with age
the frequency increases.We have greater need for thyroid hormone in pregnancy. The placenta takes some hormone and the fetus takes some thyroid hormone. At 6 weeks of pregnancy there is already evidence of our thyroid hormone in the fetus, as the fetus itself doesn't really make it's own until 20 weeks. So some experts argue that thyroid hormone levels in pregnancy should be even higher than in the non-pregnant woman. It may be recommended for women who have had a miscarriage to look into their thyroid levels carefully before a next pregnancy.
