Gastritis is a common and frequently occurring disease. Patients with chronic gastritis often have nausea, but vomiting is rare. How does chronic gastritis make a person feel disgusting, and vomit sometimes?
Some scholars believe that: chronic gastritis inflammation involving the stomach near the pyloric tube, can cause dysfunction of the pyloric tube. When the gastric peristaltic wave pushes food to the pylorus, the pylorus is not in an open state so that food can pass through and reach the duodenum, but it is still tightly closed, so that the pressure of gastric cavity is increased, and the vomiting center is reflexively stimulated, which makes people feel nauseous. When it is serious, vomiting can occur. In addition, there are often some chronic gastritis patients, combined with chronic pharyngitis, chronic esophagitis, these parts of the peripheral nerve is rich, easy to be stimulated and produce nausea.
For nausea and vomiting caused by chronic gastritis, oral metoclopramide 10 mg, twice a day; or Modelin 20 mg, 2-3 times a day.
Chronic gastritis patients, the general nausea, vomiting, most will not produce complications. But when the condition worsens, appears more severe retching or vomit, but often can cause the esophagus cardia mucous membrane tear, causes the upper digestive tract hemorrhage.
We now know that the cardia is the part of the stomach connecting the esophagus, and the cardia is generally in a closed state. When severe nausea or vomiting occurs, the pressure in the stomach rises abruptly. When the high pressure airflow is ejected from the cardia, it can cause the mucosa to tear. Most of the laceration is single, generally about 3-20 mm long and 2-3 mm wide. It is longitudinally split along the wrinkled wall of cardia mucosa.
About 10% of the upper gastrointestinal bleeding is caused by esophageal and cardiac mucosal laceration. The amount of bleeding varies. In some cases, there is little bleeding, only blood silk is contained in vomit, or there is only black stool without hematemesis; in severe patients, massive hemorrhage, shock and death may occur. The diagnosis of this disease mainly depends on the history and gastroscopy.. If there is bleeding after severe nausea and vomiting, the possibility of this disease should be considered. X-ray barium meal examination is not helpful for diagnosis. Selective arteriography is valuable in the diagnosis of patients with large amount of bleeding. Esophageal and cardiac mucosal tears can be healed within 24 hours, and the treatment is based on hemorrhagic gastritis.
Other complications of chronic gastritis vomiting include malnutrition, water and electrolyte, acid-base imbalance, which can be relieved by symptomatic treatment.
