Diabetes is a chronic condition that occurs when the body (specifically the pancreas) cannot produce or effectively use insulin. Insulin is a hormone produced by the pancreas that allows cells in the liver, skeletal muscles and fat tissue to absorb glucose from the blood. It works also to remove excess glucose from the blood, which becomes toxic at elevated levels.
The lack of insulin or inability of the body to use it effectively causes a complication because the body isn’t absorbing the glucose and getting rid of the excesses. Over time the glucose stays circulating in the blood (also known as hyperglycemia) and ends up damaging tissues.
There are three main types of diabetes:
Type 2 diabetes is the most prevalent type with about 90% of cases diagnosed as type 2.
