A person with prediabetes has a blood sugar level higher than normal, but not high enough for a diagnosis of diabetes. Without lifestyle changes, 15-30% of people with prediabetes will develop type 2 diabetes within 3-5 years. They are also at an increased risk of heart disease, and stroke.
Gestational Diabetes is a type of diabetes that develops or is first recognized during pregnancy. It usually goes away after the baby is born. However, women who have had gestational diabetes are at higher risk for developing type 2 diabetes later in life.
