Gastric sinus mucosal congestion and edema is a gastroscopic description of inflammation of the gastric mucosa. The etiologic factors may include H. pylori infection, drugs, alcohol, diet, and so on. 1. Helicobacter pylori infection: Helicobacter pylori is an acid-resistant bacillus that can evade the damage of gastric acid and settle in the gastric sinus. H. pylori can release ammonia and vacuolar toxin, which can cause damage to the gastric mucosa, thus leading to congestion and edema of the mucosa of the gastric sinus. 2. Drug irritation: Certain drugs may cause irritation to the gastric mucosa, such as aspirin. Aspirin can inhibit the enzyme cyclooxygenase, thus reducing the production of prostaglandins, so that the gastric mucosa of its own protective effect is reduced, resulting in the occurrence of gastric sinus mucosal congestion and edema. 3. Long-term alcohol consumption: alcohol has a stimulating effect on the gastric mucosa. Long-term consumption of alcohol may lead to damage to the gastric sinus mucosa, resulting in congestion and edema of the gastric sinus mucosa. 4. Diet: Eating spicy and stimulating foods, such as chili peppers and spicy hot pot, can also cause inflammation of the gastric mucosa, resulting in congestion and edema of the mucosa. When the situation of gastric sinus mucosal congestion and edema, you should consult a doctor in time, under the guidance of the doctor to improve the physical examination, C14 breath test, gastroscopy and other tests, to clarify the cause of the disease, and active treatment.
