Diabetes mellitus refers to a group of diseases that affect the way your body uses blood sugar (glucose). Glucose is vital to your health because it is an important source of energy for the cells that make up muscles and tissues. It is also the main fuel for your brain. The hidden cause of diabetes varies by type. However, regardless of the type of diabetes you have, it can lead to excess blood sugar. Too much sugar in the blood can lead to serious health problems. Chronic diabetic conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetic conditions include prediabetes, when your blood sugar levels are higher than normal, but not high enough for the disease to be classified as diabetes, and gestational diabetes, which occurs during pregnancy but can resolve once the baby is born.
