main functions of the antrum - is to reduce the acidity of stomach content before it enters the intestine with an alkaline medium, and motor function.Reducing the acidity is due to its neutralizing bicarbonates, produced by glands of the antrum.
motor or motor function of the department is carried out by means of the differential pressure between the antrum and the duodenum, resulting in food is evacuated from the stomach.The pressure difference between the different parts of the digestive tract is the driving force of motor skills and coordination, and she is governed by several factors, including the central nervous system.
clear that precisely fulfills its function healthy mucosa and muscle tissue of the stomach.Long superficial gastritis leads to painful changes in mucosal damage glands and loss of their functions, that is, to the formation of areas of atrophy.The result is a focal atrophic gastritis.
Often this process is exacerbated by
bacterium Helicobacter pylori - "megastar" among gastrointestinal diseases, it is not only the culprit helicobacter gastritis, and sometimes leads to stomach cancer.Favorite habitat of the bacteria - just antral (pyloric) stomach department, which for her comfortable environment due to the lower acidity.
H. pylori gastritis often develops at a young age.At the beginning of this gastritis gastric secretory function is not impaired, and sometimes even increased.In the propagation of the disease process, the picture changes.There are changes in the glands and mucosa of the antrum, leading to pain at the level above the umbilicus over 1-1.5 hours after a meal and can subsequently lead to a duodenal ulcer.Along with such pain intensifies regurgitation and appear hungry pain.
With Helicobacter p. Bind most of atrophic gastritis.This bacterium not only deprives the gastric wall mucus own natural defenses, destroying it, it breaks the production of bicarbonate antral glands, which is why too sour bolus enters the intestine, provoking him and disrupting the digestive process.This becomes acidic antral, resulting in rapidly progressive atrophic change and scar processes in the mucosa of the glands are killed and replaced by some uncharacteristic cells of the intestinal epithelium.Increasing atrophy foci invariably leads to functional impairment of the stomach, which manifests a whole range of symptoms.
