Type 2 Diabetes

Type 2 diabetes, the most common type of diabetes, is also one of the most prevalent chronic diseases around. World wide, more than 150 million people suffer from the disease; the International Diabetes Federation projects that this population will double globally by the year 2025. While weight is a major risk factor for type 2 diabetes, ethnic background, family history, and certain components of your health profile also play an important role.

Insulin Resistance and Type 2

Like type 1 diabetes, type 2 diabetes is a metabolic disorder in which blood glucose rises because it isn't being effectively balanced and metabolized into cell energy by insulin. The similarities in physiology between the two diseases end there, however.Type 2 diabetes is not caused by the absence of the hormone insulin, as is the case with type 1, but rather by the body's inability to use insulin properly. People with type 2 have a condition called insulin resistance. They can produce insulin, usually in sufficient amounts at first, but it doesn't bind properly to the insulin receptor that is the gateway to cells in muscle, fat, and liver tissue, and they are therefore resistant to its effects. In other words, it's like trying to fit a square peg into a round hole . As a result, glucose doesn't enter the cells and instead builds up in the bloodstream, resulting in high blood sugar levels.


The causes of type 2 diabetes are complex and not completely understood, although research is uncovering new clues at a rapid pace. Animal studies have associated certain genetic markers with the development of the disease, and its relationship with obesity has become clearer in recent years. The second condition that sets the stage for type 2 diabetes is insulin deficiency the pancreas also has difficulty producing sufficient amounts of insulin to process the rising blood glucose levels. Eventually it does not have sufficient amounts to overcome the deficit. The toxic effects of long term high glucose levels on the insulin producing beta cells on the pancreas can make insulin deficiency worse. Some people with type 2 are highly insulin resistant with a small amount of related insulin deficiency. Others are primarily insulin deficient and just slightly insulin resistant.
