effect of autonomous neuropathy on bowel preparation in type 2 diabetes mellitus

Introduction The need for colonoscopy is common among diabetics. In this study, we aimed to evaluate the effect of autonomous neuropathy on bowel preparation in type 2 diabetes mellitus (DM) patients. Materials and methods The study population consisted of 45 patients with DM and 48 non-diabetic, age- and sex-matched subjects. All colonoscopies were performed 5 h after the last dose of sodium phosphate. Colonoscopists rated the bowel preparation quality during the procedure using the Aronchick scale. All patients underwent a detailed cardiologic examination and 24-h Holter rhythm monitoring. Orthostatic hypotension and impairment in heart rate variability were accepted as indicators of autonomous neuropathy. Results Gender, age, blood pressure, and heart rates did not differ significantly between groups (p > 0.05). Autonomous neuropathy was detected in 14 (31.1%) patients in the DM group and in two (4.2%) in the control group (p
