Effects of intensive control of glycemia on the prevalence of rapid gastric emptying. Prevalence of slow, rapid and normal gastric emptying in poorly controlled T2DM (#1), mixed T1DM and T2DM (#2), and T1DM (#3); and well controlled T1DM (#4). Note that prevalence of slow gastric emptying was similar in all poorly controlled studies of T1DM or T2DM. Moreover, these rates were not significantly different from that in the well-controlled T1DM study. The prevalence of rapid gastric emptying was also similar (20%–22%) in all the poorly controlled groups. However, in the well-controlled T1DM study there was significant reduction (to 5%) in the rapid gastric emptying (p < 0.001). #1 This study includes 30 patients with poorly controlled T2DM8 #2 This study includes information on 69 patients with T2DM6 #3This study includes information on 60 patients with poorly controlled T1DM6 #4 This study includes 74 patients with well-controlled cases with TIDM.5
