The Claim

In adults with type 2 diabetes, higher postprandial glucagon-to-C-peptide index ratios are associated with reduced time in glucose target range, increased time above glucose target range, and higher average glucose levels.

In plain English

In adults with type 2 diabetes, a higher ratio of glucagon to C-peptide after meals is linked to less time spent in the normal blood glucose range, more time spent with high blood glucose, and higher average blood glucose levels.

See the scientific wording

In adults with type 2 diabetes, higher postprandial glucagon-to-C-peptide index ratios are associated with reduced time in glucose target range (TIR), increased time above range (TAR), and higher average glucose levels, suggesting that dysregulated glucagon secretion relative to insulin secretion correlates with poorer glycemic stability.

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 than needed. This floods the bloodstream with glucose, keeping blood sugar high for longer and causing wild swings in glucose levels.

  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 body releases too much glucagon compared to insulin after eating, their blood sugar stays higher and swings more wildly. This study found that this imbalance directly links to worse blood sugar control.
