Hallow Dear, Both the conditions do have the adverse effects on the baby growing in the uterus. Hypothyroid condition causes: *Increased incidence of miscarriages, recurrent pregnancy loss, preeclampsia, anaemia, pregnancy diabetes, placental abruption, bleeding after delivery *Foetal growth restriction, foetal distress during labour, foetal death, preterm birth *Cognitive, neurological and developmental impairment in the baby. Therefore there is need to screen every pregnant woman for screening test for the thyroid function. The condition can be avoided by consuming iodine rich diet like iodized salt, fruits and green leafy vegetables. In case the hypothyroidism has developed, it can be managed by levothyroxine sodium. High levels of TSH indicate hypothyroidism. They should be maintained below 2.5 mIU/L. Diabetes is a very complex metabolic disorder. It also may affect foetal growth. Many a times, the baby of the diabetic mother is overweight and still behaves like a premature child. Diabetes can also cause miscarriages, foetal anomalies, high blood pressure etc. Sudden intrauterine death or death during delivery are classic complications of diabetes during pregnancy. Hence critical monitoring of diabetes is mandatory. During pregnancy, naturally. Even normal blood sugar also may show sugar in the urine. Hence the monitoring of the blood sugar is mandatory in pregnancy with diabetes. The diabetes can be effectively controlled by restriction on the diet, oral anti-diabetic medicines and insulin injections. If there is high blood pressure during pregnancy in association with these conditions, the ill effects are enhanced. Hence control of all three are critically important. I hope this will make you aware of the conditions sufficiently and encourage to take further actions.
