Blood sugar postprandial is the measurement of blood glucose levels taken a set time after eating, often two hours after a meal. It provides insight into how effectively the body manages sugar spikes following food intake and can reveal impaired glucose tolerance even when fasting glucose is near normal. In underwriting, postprandial readings may appear in attending physician statements or specialty lab work and, along with A1c and fasting levels, help form a fuller picture of diabetic control. Persistently high postprandial glucose is associated with endothelial damage, cardiovascular risk, and progression of diabetes complications over time.

Underwriters review blood sugar postprandial values when they are documented in medical records for diabetic or prediabetic applicants. They look for trends, such as consistently high post-meal readings despite treatment, which may indicate suboptimal control and justify higher ratings. Advisors may not routinely order postprandial tests for underwriting but should recognize their significance when clients share endocrinology reports. In conversations, they can explain why both fasting and post-meal control matter to insurers and to long-term health. Understanding blood sugar postprandial allows advisors to interpret physician notes more accurately and prepare clients for potential underwriting responses to marginal control.
