Congestion and edema of the gastric fundus mucosa is a manifestation of gastroscopy, which often suggests the presence of inflammatory changes in the gastric mucosa. Inflammation of the gastric mucosa may be caused by a history of alcohol consumption, spicy and stimulating foods, Helicobacter pylori infection, excessive mental stress, and taking certain medications, such as aspirin, which stimulate the gastric mucosa, leading to gastric mucosal damage causing congestion and edema. Congestion and edema of the gastric fundus mucosa can usually be accompanied by epigastric pain, acid reflux, nausea, heartburn and other symptoms. The congestion and edema of the gastric fundus mucosa can be treated with acid-suppressing drugs, such as omeprazole, rabeprazole, etc., combined with colloidal bismuth pectin. If Helicobacter pylori infection is present, antibiotics, such as amoxicillin and clarithromycin, can be added to the treatment. It is recommended to treat with medication under the guidance of a physician, do not take medication on your own.
