Do HbA1C Levels Correlate With Delayed Gastric Emptying in Diabetic Patients?

Abstract

Gastroparesis is characterized by delayed gastric emptying without obstruction. Diabetes is frequently associated with poor glycemic control and delayed gastric emptying. Gastric emptying scintigraphy (GES) is the standard for measuring gastric emptying. Serum hemoglobin A1C (HbA1C) measures prolonged glycemic control with normal as < 7% glycated. To date, no correlation of serum HbA1C level with gastric emptying, demonstrated by GES, in diabetics has been performed. The aim of the present investigation is to determine if a relationship exists between serum HbA1C levels and gastric emptying, assessed by GES, in diabetics.
