What's the difference between type 1 and 2 diabetes?

Type 1..: Requires Insulin to live type 2 can often be controlled with diet, exercise pills;sometimes need Insulin for better control, but won't pass away if no Insulin unless very poorly controlled.

Very different: Both types of diabetes are characterized by high blood glucose levels. Type i diabetes is caused by a failure of the islet cells in the pancreas to produce insulin. Insulin is a hormone that is required to get glucose into the cells. In type ii diabetes, the pancreas produces Insulin but the cells don't use the Insulin in a normal fashion. This is sometimes called Insulin resistance.
