Belching but no stomach pain is mainly due to gastrointestinal disorders such as reflux esophagitis, chronic gastritis, and functional dyspepsia. Patients need to visit a hospital promptly and undergo gastroscopy or abdominal ultrasound to clarify the cause before treatment. Common causes and treatment usually include inadequate gastric motility, reduced secretion of digestive enzymes, overproduction of gastric acid and improper diet, which can cause inflammatory or ulcerative lesions in the gastrointestinal tract, resulting in uncomfortable symptoms such as epigastric fullness, belching and acid reflux. Gastrointestinal disorders need to be treated with drugs and surgery to address the causes. For example, drugs such as omeprazole and rabeprazole can be used to inhibit gastric acid secretion, and drugs such as domperidone and mosapride can be used to promote gastric motility to relieve belching. Precautions In daily life, patients also need to improve their lifestyles and develop good eating habits. In terms of lifestyle, overeating and irregular diet need to be avoided, and attention should be paid to combining work and rest to avoid staying up late or overworking. You can also exercise properly and keep your mood relaxed to promote gastrointestinal peristalsis, help food consumption and absorption, and reduce gastrointestinal discomfort. In the diet, you need to quit smoking, quit drinking, try not to eat greasy, spicy and other stimulating food, but can eat more fresh fruits and vegetables, such as apples, celery, etc.
