After eating chili peppers, the stomach burns badly. This symptom is most likely caused by chili peppers stimulating gastric acid reflux upward and bile reflux upward, which is directly related to chili peppers stimulating gastric and duodenal peristaltic disorders, and is mostly seen in reflux esophagitis, bile reflux gastritis and gastric ulcer, which requires an electronic gastroscopy to clarify. If it is clear that it is reflux esophagitis, it needs to be treated with drugs such as mosapride citrate plus omeprazole for more than three weeks. If it is clear that it is bile reflux gastritis, it needs to be treated with Mosapride citrate plus sodium ursodeoxycholate and aluminum phosphate gel; if the eGastroscopy is clear that it is gastric ulcer or duodenal ulcer, this condition needs to be treated with Eprazole plus Rehabin solution. When you have the above symptoms, you can no longer eat spicy, fried and other stimulating foods, do not overeat, and be sure to stop drinking.
