The only way to effectively reverse type 2 diabetes (or even pre-diabetes) is to deal with the underlying cause – Insulin Resistance. Trying to address the blood sugar levels (with medication) without addressing the insulin levels is treating the symptoms, not treating the root cause. It is similar to using a bucket to remove water from an overflowing sink rather than actually turning off the tap!
Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
