If you have diabetes and are planning to become pregnant, it's crucial to manage your condition carefully. High blood sugar levels during pregnancy can lead to complications for both mother and baby, including gestational diabetes, birth defects, and larger-than-average babies. It's important to achieve good glycemic control before conception and throughout your pregnancy. Regular check-ups with your GP and an obstetrician will help monitor your health and your baby's development. A tailored care plan, including diet, exercise, and possibly medication adjustments, can support a healthy pregnancy.
