Scientists have now discovered a new drug that may help prevent diabetes.
This could prevent obese patients and others at risk of Type 2 -diabetes from ever getting the disease.
Scientists say the innovative drug, known as MK2, could be added to metformin, the current first-line treatment for the illness, to create a super-pill, the Daily Express reported.
The experts believe the combined drug would be especially useful in treating seriously over-weight patients as it prevents insulin cells "burning out" as they try to cope with obesity.
The drug may also stop those who are in the early stages of the illness - a condition known as "pre-diabetes" - from getting it, according to the research.
The findings are published in the journal Cell Metabolism.
