Theoretical studies of prevalence of obesity and type 2 diabetes mellitus

Diabetes is a metabolic condition in which the body does not produce sufficient insulin to regulate blood glucose levels or where the insulin produced is unable to work effectively. There are two main types of diabetes: Type 1 diabetes is an auto-immune condition in which the cells that produce insulina are destroyed so lifelong treatment with insulin is required to prevent death. About 10% of people with diagnosed diabetes have type 1 diabetes. Type 2 diabetes accounts for at least 90% of all cases of diabetes. It occurs when the body either stops producing enough insulin for its needs or becomes resistant to the effect of insulin produced. The condition is progressive requiring lifestyle management at all stages. Over time most people with type 2 diabetes will require oral drugs and or insulin. Type 2 diabetes may remain undetected for many years. Obesity is only associated with type 2 diabetes and this paper does not cover type 1 diabetes, which has no association with obesity or other lifestyle factors, or other forms of diabetes such as gestational diabetes.
