The Claim

In Japanese adults with type 2 diabetes, two weeks of treatment with linagliptin or liraglutide does not impair the glucagon response to induced hypoglycemia at 2.5 mmol/L, as measured by plasma glucagon levels during a hypoglycemic clamp test.

Description
1 study reviewed
In plain English

In Japanese adults with type 2 diabetes, two weeks of treatment with linagliptin or liraglutide does not reduce the increase in plasma glucagon levels when blood sugar is lowered to 2.5 mmol/L during a controlled test.

See the scientific wording

In Japanese adults with type 2 diabetes, two weeks of treatment with the DPP-4 inhibitor linagliptin or the GLP-1 receptor agonist liraglutide does not impair the glucagon response to induced hypoglycemia at 2.5 mmol/L, as measured by plasma glucagon levels during a hypoglycemic clamp test, suggesting both drugs preserve this critical counter-regulatory defense against low blood sugar.

Why this might work

When blood sugar drops, pancreatic alpha cells release glucagon to raise it back up; this response stays strong even when drugs block the breakdown of GLP-1 or activate its receptor, because the alpha cells still sense low glucose and respond directly without being suppressed.

    The study found that two weeks of taking either linagliptin or liraglutide didn’t stop the body from releasing glucagon when blood sugar drops too low — which is good because glucagon helps raise blood sugar back up and prevents dangerous lows.
