Causes of Diabetes
Insulin is a hormone made by the pancreas to control blood sugar. Insulin helps to move glucose from the bloodstream into muscle, fat and liver cells, where it can be saved for use as energy.
People with diabetes have high blood sugar because their body cannot move sugar from the blood into muscle and fat cells to be burned or stored for energy. This is because either their pancreas does not make enough insulin or their cells do not respond to insulin normally or both.
There are two major types of diabetes — type 1 and type 2 diabetes. The causes and risk reasons are different for each type.
Type 1 Diabetes
Type 1 diabetes can happen at any age, but it is most often found in children, teens or young adults. In this disease, the body makes little or no insulin because the pancreas cells that make insulin stop working.
Type 2 Diabetes
Type 2 diabetes is much more common. It most often happens in adulthood. However, due to high obesity rates, teens and young adults are now being spotted with this disease.
