1) What is diabetes in pregnancy, also known as gestational diabetes mellitus (GDM)?
Diabetes that develops during pregnancy is known as gestational diabetes. It occurs because the body cannot produce enough insulin which is a hormone important in controlling blood glucose to meet its extra needs in pregnancy. This results in high blood glucose levels. Gestational diabetes usually starts in the middle or towards the end of pregnancy.
2) What causes diabetes during pregnancy, and can it be prevented?

Because of these changes, the body’s cells don’t use insulin well, a condition called insulin resistance. All pregnant women have some insulin resistance during late pregnancy. Most pregnant women can produce enough insulin to overcome insulin resistance, but some cannot. These women develop gestational diabetes. As for prevention, before embarking into a pregnancy, if a woman is overweight, losing weight with regular physical activities may help in preventing gestational diabetes.
