Rosiglitazone (Avandia) and pioglitazone (ACTOS) are in a group of drugs called thiazolidinediones. These drugs help insulin work better in the muscle and fat and also reduce glucose production in the liver. The first drug in this group, troglitazone (Rezulin), was removed from the market because it caused serious liver problems in a small number of people. So far rosiglitazone and pioglitazone have not shown the same problems, but users are still monitored closely for liver problems as a precaution. Both drugs appear to increase the risk for heart failure in some individuals, and there is debate about whether rosiglitazone may contribute to an increased risk for heart attacks. Both drugs are effective at reducing A1C and generally have few side effects.
There was a clinical trial conducted at Department of Biochemistry, Postgraduate Institute of Basic Medical Sciences Madras, India that studied 22 patients with type 2 diabetes. It reported that supplementing the body with 400 mg of Gymnema Sylvestre extract daily resulted in remarkable reductions in blood glucose levels, hemoglobin A1c and glycosylated plasma protein levels. What’s even more remarkable is that by the end of this 18 month study, participants were able to reduce the dosage of their prescription diabetes medication. Five were even completely off medication and attaining stable blood sugar levels with Gymnema Sylvestre supplementation alone.
The advice above is therefore not only illogical, but also works poorly. It completely lacks scientific support according to a Swedish expert investigation. On the contrary, in recent years similar carbohydrate-rich dietary advice has been shown to increase the risk of getting diabetes and worsen blood sugar levels long-term in people who are already diabetic. The advice doesn’t improve diabetics’ health in any other way either.
