The Claim
In adults with type 2 diabetes, red blood cell lifespan is negatively correlated with average blood glucose levels (r = −0.33, p < 0.0001), indicating that higher average blood glucose is associated with shorter red blood cell survival.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you have type 2 diabetes, having higher blood sugar over time might mean your red blood cells don’t live as long.
See the scientific wording
In adults with type 2 diabetes, red blood cell lifespan is negatively correlated with average blood glucose (r = −0.33, p < 0.0001), indicating that higher glucose levels are associated with shorter red blood cell survival.
What the research says
1 studyStudy: Red Blood Cell Lifespan < 74 Days Can Clinically Reduce Hb1Ac Levels in Type 2 Diabetes
The study looked at how long red blood cells live in people with type 2 diabetes and how that relates to blood sugar. It found that people with shorter-lived red blood cells had higher average blood sugar, which matches the claim, but didn’t directly test or confirm the strength of that link.
