Diabetes affects how your body uses blood glucose (blood sugar). The main types of diabetes include type 1 diabetes, type 2 diabetes, and gestational diabetes. Types one and two are chronic issues that need to be managed with the help of your doctor. However, prediabetes and gestational diabetes are potentially reversible.
Type 1 diabetes was once known as juvenile diabetes. It can develop at any age, but typically appears during childhood. Type 1 diabetes is a condition where the pancreas produces little or no insulin, a hormone that is needed to allow sugar (glucose) to enter cells to produce energy.
Type 2 diabetes is far more common than type 1. Once known as adult-onset diabetes, type 2 diabetes occurs when the body begins to resist the effects of insulin, or it doesn't make enough of it.
Gestational diabetes occurs only during pregnancy. It can cause high blood sugar levels that are unlikely to cause problems for you, but can put the health of your unborn baby at risk. Blood sugar levels usually normalize soon after delivery.
No matter what type of diabetes you have, it means there is too much glucose in your blood. Too much glucose can lead to serious health problems.
