Some earlier reports published in various journals showed a connection between hepatitis C virus infection and the risk of developing type 2 diabetes.

To further investigate the relationship between hepatitis C infection and Diabetes risk, the researchers studied 564 patients with hepatitis C, 82 with hepatitis B virus infection and a comparison group of 302 matched but uninfected “controls”.

The results indicated that 12.6% of the hepatitis C virus patients had diabetes, significantly more than the 4.9% of the hepatitis B patients or the 7% of the controls. This data suggests that hepatitis C related liver disease is associated with diabetes at a stage when the liver function is still largely preserved.
