Pregestational Diabetes Mellitus and Pregnancy

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Perinatology

Background:

• Diabetes in pregnancy poses significant risks to fetal development, including congenital malformations, macrosomia, and stillbirth.
• Maternal health can be adversely affected by diabetes, with potential worsening of complications like retinopathy and nephropathy.
• Pregnancy complicated by diabetes is associated with increased rates of hypertension, pre-eclamptic toxaemia, and intrauterine growth restriction.

Purpose of the Study:

• To summarize the risks associated with diabetes in pregnancy.
• To highlight the impact of diabetes on both fetal and maternal outcomes.
• To emphasize the importance of glycemic control for a positive pregnancy outcome.

Main Methods:

• This is a review of known risks and outcomes in pregnancies complicated by diabetes.
• Information synthesized from existing literature on maternal-fetal medicine and diabetes in pregnancy.
• Analysis of risk factors and complications based on current medical understanding.

Main Results:

• Fetal risks include congenital malformations, macrosomia, and stillbirth.
• Maternal risks include worsening of diabetic complications (retinopathy, nephropathy), hypertension, pre-eclamptic toxaemia, and intrauterine growth restriction.
• Good glycemic control and absence of diabetic complications are associated with normal pregnancy outcomes.

Conclusions:

• Effective diabetes management is crucial for mitigating risks in pregnancy.
• Women with well-controlled diabetes and no complications can achieve normal pregnancy outcomes.
• Close monitoring and management are essential for pregnancies affected by diabetes.
