Abstract
Background and Aims
Upper gastrointestinal symptoms are more prevalent among type 2 diabetes mellitus (T2DM) patients. The prevalence of delayed gastric emptying (GE) and factors predictive of it have not been studied in Indian T2DM patients and the present study aimed to study the same.
Methods
This hospital-based cross-sectional study involved adult (age between 18 and 65 years) outpatients with T2DM of ≥5-year duration. Measurements of GE of a labelled standardized solid rice idli meal by gastric emptying scintigraphy (GES), symptoms of delayed GE (by standardized questionnaire) and autonomic function by cardiovascular autonomic function tests (AFTs) were carried out. Thirty healthy subjects served as controls for GES and AFTs.
Results
One hundred and forty T2DM patients (age range: 32–65 years) were studied. Delayed GE was documented in ≈29 % (40/140) and rapid GE in 2 % (3/140) of T2DM patients. Univariate analysis showed significant positive association between delayed GE and duration of DM, body mass index (BMI), HbA1c, retinopathy, peripheral neuropathy, autonomic dysfunction and coronary artery disease (p < 0.05 for all). However, there was no significant correlation of age, sex, symptoms suggestive of gastroparesis and nephropathy with delayed GE. Hypoglycemic episodes were significantly more frequent in those with delayed GE (p < 0.05). Multiple logistic regression analysis revealed only BMI and HbA1c to be significant independent predictors of delayed GE.
Conclusion
Presence and severity of symptoms of gastroparesis did not predict delayed GE. Delayed GE, irrespective of symptoms, was associated with microvascular and macrovascular diabetic complications and increased risk of hypoglycemic episodes. HbA1c and BMI were independent predictors of delayed GE.
