BACKGROUND: Impairment of gastric emptying is well recognized in patients with diabetes mellitus (DM), especially long-standing insulin-dependent diabetes mellitus (IDDM). The aim of this study was to evaluate the cause of delayed gastric emptying in DM patients. METHODS: In 16 controls, 16 non-insulin-dependent diabetes mellitus (NIDDM) patients and 23 IDDM patients, gastric emptying was studied using the (13)C octanoic acid breath test. Breath samples were taken before a test meal labeled with 100 mg of (13)C octanoic acid, and at 15-min intervals over a 300-min period postprandially. RESULTS: In all DM patients, the gastric emptying coefficient was lower than that in the controls (P < 0.05), and lag time and half-emptying time were significantly longer (P < 0.05). Both NIDDM and IDDM patients showed delayed (13)CO(2) excretion compared with the controls, but IDDM patients showed more delayed gastric emptying than NIDDM patients (P < 0.05). There were no significant differences in sex, HbA1c level, or the rate of neuropathy between the two groups. CONCLUSIONS: IDDM patients showed delayed gastric emptying compared with NIDDM patients, and the (13)C octanoic acid breath test is useful for evaluating DM patients with delayed gastric emptying.
