The Claim

In patients with type 2 diabetes and HbA1c levels below 7%, those with a red blood cell lifespan shorter than 90 days exhibit significantly higher fasting blood glucose, 2-hour postprandial glucose, and average glucose levels compared to those with a red blood cell lifespan of 90 days or longer, despite having similar HbA1c values.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Even when blood sugar averages look good on a diabetes test, people with shorter-lived red blood cells might still have higher actual sugar levels throughout the day.

See the scientific wording

In type 2 diabetes patients with HbA1c <7%, those with red blood cell lifespan <90 days have significantly higher fasting blood glucose (7.41 vs 6.88 mmol/L), 2-hour postprandial glucose (9.61 vs 8.80 mmol/L), and average glucose (8.30 vs 7.74 mmol/L) compared to those with RBC lifespan ≥90 days, despite similar measured HbA1c levels.

    People with shorter-lived red blood cells may have higher blood sugar than their HbA1c test shows, and this study found evidence that supports this idea.
