I have been avoiding taking Metformin for years. My A1C has been between 6.0 and 7.4 for the last 6 years. I have been managing it with constantly improving diet and exercise. I have hepatitis C and was told by a doctor that Metformin was one of the worst things for the liver. Is that true?
Metformin is considered the first line medication for the treatment of type 2 diabetes. It is effective at lowering glucose levels without hypoglycemia or weight gain. Although very effective, metformin is contraindicated if significant liver or kidney disease is present. Metformin does not adversely affect liver function, but should not be used if there is significant underlying liver disease. Hepatitis C can cause variable liver dysfunction. If liver disease is only mild, metformin can still be considered. You should discuss the degree of your liver disease with your healthcare provider and whether you would be a candidate for metformin to help control your blood glucose levels.
