Study On Bio-Impedance Gastric Motility In Type 2 Diabetes

Objective: To detect the gastric motility in 65 patients with type 2 diabetes , and to explore the relationship between gastric motility disorder of the diabetes and the influential factors.Methods: Collecting the gastric motility in the patients by wavelet transform bio-impedance system. Fasting blood glucose (FBG) was detected by the oxidation enzyme method, while microcolumn method was adopted to test glycosylated hemoglobin (HbA1c).Results:1. Thirty five patients in our group had abnormal gastric motility with an occurrence of 53.85%.The percentage of the dominant frequency of impedance gastrogram in the DM group was much lower than that in the normal controls (53.98±5.89% vs 56.52±5.29%,p<0.05).2. The percentage of the dominant frequency of the EGG in the HbA1c above 6.5% was significantly lower than that in the HbA1c below 6.5% (p<0.01).3. The percentage of the bradygastria in the elder (35.36±3.96)was much higher than that in the youth(30.7±3.55) and in the middle-aged (31.76±4.93)(p<0.05).4. Gastric motility disorder had no correlation to FBG and the course of disease.Conclusion: The incidence of gastric motility disorder was very high in the DM patients. The gastric motility disorder was much easier to occur in the abnormal HbA1c and the elder , while it had no correlation with FBG and the duration of the illness.
