Acute gastric mucosal lesions are a more serious condition that is characterized by varying degrees of erosion, superficial ulceration and bleeding of the gastric mucosa. It is usually associated with a history of taking the drug in question, alcohol abuse, or a disease that causes a stressful state. The most prominent clinical symptom in patients is upper gastrointestinal bleeding, which may manifest as black stools or vomiting of blood. The bleeding is indirect, recurrent and multiple, and is often accompanied by epigastric pain, nausea, vomiting and acid reflux. In severe cases, it may lead to anemia, syncope and even hemorrhagic shock. When pre-acute gastric mucosal lesions occur, prompt hospital consultation is recommended. And under the guidance of the doctor, treatment is carried out to inhibit gastric acid secretion, protect gastric mucosa, stop bleeding, replenish blood volume to improve anemia and other symptoms, and diet requires fasting or dregs-free liquid food during the acute period. Daily attention to dietary cleanliness and hygiene, do not eat spicy, irritating food, quit smoking and alcohol.
