The Claim

In adults with type 2 diabetes, elevated postprandial glucagon-to-C-peptide index ratios are associated with elevated average glucose levels, suggesting that relative glucagon excess contributes to sustained hyperglycemia independent of insulin deficiency.

In plain English

In adults with type 2 diabetes, higher ratios of glucagon to C-peptide after meals are linked to higher average blood glucose levels, indicating that excess glucagon relative to insulin production contributes to persistently high blood sugar.

See the scientific wording

In adults with type 2 diabetes, higher postprandial glucagon-to-C-peptide index ratios are associated with higher average glucose levels, indicating that relative glucagon excess may contribute to sustained hyperglycemia beyond insulin deficiency.

Why this might work

After eating, the pancreas releases too much glucagon and not enough insulin, causing the liver to make and release more sugar into the blood than needed, which keeps blood sugar levels high for longer.

  1. Study: 77-OR: Time in Range Is Associated with Glucagon/C-Peptide Index Ratio in Type 2 Diabetes Patients

    In people with type 2 diabetes, when the hormone glucagon is high compared to insulin after eating, their blood sugar tends to stay higher and swing more — this study found that link clearly.
