Do you have to have an endoscopy for belching?

Patient's question:

Problem Description: Half a year ago, one day I suddenly had chest pain and was woken up from sleep by vomiting, feeling extremely miserable and having difficulty breathing. At the time, I thought it was just because I ate something uncomfortable and didn't pay attention to the belching. A week later, I bought some medicine from a pharmacy myself, and the condition improved somewhat. However, it has been recurring ever since, and I also experience this when I'm in a bad mood. Sometimes I vomit, and when I can't vomit anymore, I start to have acid reflux with a burning sensation in my chest. At times, the vomited air has a certain smell, and my chest hurts. After realizing it was belching, I went to the hospital yesterday, but the doctor wanted me to have an endoscopy because I had just eaten lunch and couldn't do it then. Later, I heard that having an endoscopy is very painful, so I wanted to know—is it absolutely necessary to have an endoscopy? Is there no alternative?

Doctor's answer:

Hello, your problem is not serious—it's just bile reflux gastritis and esophagitis. If you can receive systematic and standardized treatment, there shouldn't be any major issues. Pathological tests should be conducted as routine examinations. The cause of the condition is long-term chronic inflammation, poor hygiene in diet, and irregular lifestyle, which leads to the local barrier of the gastric mucosa being damaged, causing bleeding, erosion, and ulcers. In severe cases, it may lead to scar formation, pyloric stenosis, and relaxation of the lower esophageal sphincter, resulting in reflux esophagitis. 95% of stomach diseases are accompanied by Helicobacter pylori (HP) infection. Combined with the stimulation of gastric acid secretion from three meals a day, the condition tends to recur easily. Therefore, the key to treatment is to use medications systematically and according to prescribed courses. It is recommended to use:
Omeprazole capsules twice a day, one capsule each time, taken on an empty stomach in the morning and evening. Domperidone tablets, one tablet three times a day, taken before meals. Anti-inflammatory and gallbladder-relieving tablets, five tablets three times a day, taken before meals. Amoxicillin capsules, two capsules three times a day, taken before meals. Metronidazole tablets, one tablet three times a day, taken before meals.
After taking these medications for one week, you should see significant improvement. It is best to continue taking them for a full month and then follow up for a check-up. To reduce the likelihood of recurrence, it is important to maintain a healthy lifestyle, get adequate rest, and eat less spicy, greasy, or irritating foods, especially avoiding smoking and alcohol. Instead, focus on consuming more vegetables, fruits, and green foods.
