Post-Meal Glucose Genetics Linked to Lacunar Stroke Risk
A 2026 medRxiv genetic analysis linked type 2 diabetes and 2-hour postprandial glucose — the blood-sugar rise after an oral glucose challenge — to higher lacunar stroke risk, with a stronger direct signal for post-meal glucose than for HbA1c after adjustment for brain small-vessel imaging markers.1 Research Highlights Lacunar stroke was the clearest endpoint: genetically …
