[Clinical value of time course changes in postprandial intragastric acidity]
Aim:
to study the level and duration of postprandial pH abnormalities in the body of the stomach in healthy individuals and in patients with duodenal peptic ulcer (DPU).
Subjects And Methods:
24-hour pH-metry was used to study the degree and duration of postprandial pH abnormalities in the body of the stomach in 50 healthy individuals and 188 patients with DPU.
Results:
Interdigestive gastric pH in healthy individuals was significantly higher than that in patients with DPU; food intake was followed by an 86 +/- 3.4% increase in pH, the latter returned to the baseline pH values within 64.7-70.3 minutes. In the uncomplicated course of DPU, the mean postprandial pH increase was comparable in the level and duration with the similar indices in healthy individuals. Complicated DPU was characterized by a short-term and insignificant increase in postprandial pH.
Conclusion:
The mean postprandial pH increase and the time of its return to the baseline level in uncomplicated DPU were comparable with those in healthy individuals; there was a significant reduction in these indices in complicated DPU.

The acid-secreting gastric mucosal epithelial cells (parietal cells) lining the stomach lumen maintain the low pH in the lumen. Numerous ion transporters and channels on these parietal...

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Gastric Phase of Digestion
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...
