Abstract

Exaggerated plasma concentrations of GLP-1 precede reactive hypoglycemia after oral glucose in gastrectomy patients, resulting in late dumping syndrome. Recently, we showed that GLP-1 elicits the activation of sympathetic outflow. Because sympathetic activation is thought to be a cause of early dumping, we hypothesized that exaggerated GLP-1 may contribute to the pathophysiology of early dumping syndrome. In 11 patients after gastrectomy and 14 controls, blood pressure, heart rate, and plasma concentrations of norepinephrine, epinephrine, GLP-1, glucagon, insulin, and glucose were measured after oral glucose. In gastrectomy patients, GLP-1, norepinephrine, and heart rate peaked 15 to 30 min after oral glucose. Significant positive correlations were found among GLP-1, norepinephrine, and heart rate at 30 min, and these parameters at 30 min were significantly higher in patients with early dumping syndrome. These results suggest that GLP-1 is involved in the pathophysiology of early dumping syndrome.

  • GLP-1 has been implicated to cause tachycardia in patients who have rapid gastric emptying after gastric resection (postgastrectomy dumping syndrome).

    “GLP-1 has also been implicated to cause tachycardia in patients who have rapid gastric emptying after gastric resection (i.e., postgastrectomy dumping syndrome), because these patients have increased heart rate, plasma GLP-1, and plasma norepinephrine concentrations after an oral glucose challenge (54).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
