Dr. James Chu
Endocrinology 26 years experience
Glucose levels rise: High blood sugar before pregnancy means either pre-diabetes or type 1 or type 2 diabetes. If not already treated (such as for pre-diabetes) prior to conceiving, then the future pregnancy state's various placental hormones can cause the glucose levels to increase out of control. High glucose can cause problems for baby: excessive weight, hypoglycemia at birth, higher risk of future type 2 dm, etc.
Dr. Larry Deeb
Pediatrics 49 years experience
Birth defects: High glucose in the first few weeks of pregnancy, during the time when the organs are being created, causes birth defects. That is why women with diabetes should plan pregnancies and do her best to have the very best control before becoming pregnant and throughout the pregnancy.
