Proximal stomach

For the most part, the resting pH of the stomach is nearer to 2 than 1 however, during feeding the meal causes a transient rise in pH to 4—5 depending on the volume and nature of the meal consumed. The fundus undergoes receptive relaxation to allow the proximal stomach to accommodate the food mass in the distal stomach, the food is triturated to form chyme, which is ejected into the duodenum in spurts of 2-5 mL. The division of function causes significant inhomogeneity in... [Pg.551]

Following meals, food is stored in the upper part of the stomach, and approximately 5-10 min after food ingestion, the stomach motor activity starts and persists as long as the food exists in the stomach (2-4 hr). The peristaltic contractions of the proximal stomach slowly... [Pg.1850]

Functional ultrasound of the gastrointestinal (GI) tract includes studies of the distal and proximal stomach, gastric and gallbladder emptying, gastric distribution, Gl wall motility, and flow of luminal contents in healthy subjects as well as in patients. Furthermore, it includes the effect of different meals and pharmacological intervention. [Pg.189]

The soup emptied from the proximal stomach in a linear manner with a moderate day-to-day variation, low intra- and interobserver error, and tihe method allows estimation of initial emptying fractions of the proximal stomach (Gilja et al. 1995). [Pg.191]

Ultrasound of the proximal stomach has shown that patients with functional dyspepsia and diabetes have a smaller proximal stomach than healthy subjects (Gilja et al. 1996 Undeland et al. 1998). Sublingual glyceryl trinitrate improves accommodation of the proximal stomach to a meal as measured by ultrasound and reduces postprandial symptoms in a group of patients with functional dyspepsia (Gilja et al. 1997X... [Pg.191]
