Gastritis with celiac disease can be improved by adjusting diet and medication. 1. Adjust the diet: eat a light diet, regular meals, avoid spicy stimulation, greasy food. Try to suspend taking drugs that damage the gastric mucosa, such as aspirin. 2. Medications: If patients have symptoms of acid reflux and stomach pain, they can use proton pump inhibitors for acid suppression under the guidance of doctors, such as omeprazole; if they have symptoms of bloating and indigestion, they can use drugs to promote gastric motility such as domperidone and trimethoprim; if accompanied by bile reflux, they can also be combined with gastric mucous membrane protectors such as Rebapatide. The above drugs should be used under the guidance of a professional physician. If you have gastritis with erosion, you need to consult a doctor in time and actively cooperate with the doctor for treatment to avoid delaying the condition.
