Diabetes mellitus refers to a group of diseases that affect how your body uses blood glucose, commonly called blood sugar, especially in Africa.

Glucose is very important to your health because it is an important source of energy for the cells that make up your muscles and tissues. In otherwords it is also your brain’s main source of fuel.

If you have diabetes, no matter what type, it means you have too much glucose in your blood, although the reasons for causing it may differ. Too much glucose can lead to serious health problems.

Chronic diabetes conditions may include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes — when your blood sugar levels are higher than normal, but not high enough to be classified as diabetes— and gestational diabetes, which occurs during pregnancy but may resolve after the baby, is delivered
To understand diabetes, first you must understand how glucose is normally processed in the body.
