Diabetes is a serious metabolic disorder and it has reached epidemic proportions globally. This disease happens as a result of insulin resistance in the body. A recent study at Université de Genève says that insulin imbalance may not be the only reason behind diabetes. Researchers say that obesity also promotes resistance to insulin and is major risk factor. According to them the liver can also contribute to the onset of this disease by producing a significant amount of glucose outside of any hormonal signal. And if a person is obese this excess production of glucose may cause type 2 diabetes.
