Causes of diabetes type 2
Causes of diabetes type 2 vary depending on your genetic makeup, family history, ethnicity, health and environmental factors. There is no common diabetes cause that fits every type of diabetes. The reason there is no defined diabetes cause is because the causes of diabetes vary depending on the individual and the type.
How insulin works
Insulin is like a key that opens up the locks on your bodys cells so that glucose (blood sugar) can get inside and be used for energy. If the glucose can not get into your cells, it builds up in your blood stream. If left untreated, high blood glucose can cause long-term complications.
The role of glucose
Sugar has a bad reputation, but there is one type of sugar, called glucose, that your body needs to function. Glucose is a monosaccharide or single sugar. When you eat a carbohydrate, like a piece of bread or bowl of cereal, your body breaks the food down into small molecules, including glucose, that your body can absorb. Glucose enters the bloodstream and travels to every part of the body to fuifill its essential purpose.
Causes of type 1 diabetes
The exact cause of type 1 diabetes is unknown. What is known is that your immune system, which normally fights harmful bacteria or viruses, attacks and destroys your insulin-producing cells in the pancreas. This leaves you with little or no insulin. Instead of being transported into your cells, sugar builds up in your bloodstream. Type 1 is thought to be caused by a combination of genetic susceptibility and environmental factors, though exactly what many of those factors are is still unclear.
