How fast does A1C change?

The A1C test measures your average blood sugar levels over the past 2-3 months, as it reflects the lifespan of red blood cells. Here’s what you need to know:

• Timeframe: A1C changes gradually over weeks to months, not overnight.
• Impact of Lifestyle Changes: Significant changes in diet, exercise, or medication can start to show in your A1C levels within 1-2 months.
• Consistency: Maintaining consistent blood sugar control is key to seeing a steady decline in A1C.

For example, if you improve your diet and increase physical activity, you may see a noticeable change in your A1C after 2-3 months. However, individual results may vary based on factors like medication adherence and overall health.
