WebNov 1, 1998 · Gastrin is a potent stimulus for gastric acid secretion . A potential effect of gastrin on gastrointestinal motility may be dependent on, or regulated through, intraluminal acidification by increased gastric acid secretion. Therefore, intraluminal acidity was recorded simultaneously. WebHypergastrinemia occurs when levels of gastrin become higher than usual. Gastrin is a hormone that affects the levels of gastric acid in your stomach. These acid levels can be either higher or lower than normal. Hypergastrinemia has many causes, including long …
