how much can a1c drop in 3 months on metformin

The reduction in A1C levels while taking metformin can vary depending on individual factors such as baseline A1C, adherence to medication, diet, and lifestyle changes. However, studies and clinical experience suggest the following:

• Typical Reduction: On average, metformin can lower A1C by 1% to 1.5% over 3 months.
• Higher Baseline A1C: Individuals with higher initial A1C levels (e.g., 9% or above) may see a more significant drop, sometimes up to 2% or more.
• Lifestyle Changes: Combining metformin with a healthy diet, regular exercise, and weight loss can enhance A1C reduction.

For example:
