<s>[INST] If obesity is linked with diabetes then why don’t some morbidly obese people have diabetes? [/INST] Type II diabetes is a complex disorder. Many factors responsible are: genetic tendancy, pancreatic function, sesitivity of muscles to insulin, fat stores in the liver as well as grade of activity and lifestyle. Even though, some patients with morbid obesity do not have diabetes, their pancreas secretes higher level of insulin due to the insulin resistance. Insulin resistance varies from person to person. Hence everyone with morbid obesity does not necessarily get diabetes but may have pre diabetes or weight related co-morbidities and fatty liver disease. At the same time some people woth lesser grade of obesity maty have diabetes. thorough investigations to know the type of diabetes, pancreatic function are necessary since there are many genetic variants of diabetes which appear like type 2 diabetes but they are not.
