Burping and spitting up acidic water can be improved by dietary modifications, medication, and surgery. Common factors that cause hiccups and acid reflux include eating more gas-producing food, excessive secretion of gastric acid, and gastroesophageal reflux disease (GERD). 1 eat more gas-producing food: food into the stomach, can stimulate gastric acid secretion. Soybeans, potatoes, sweet potatoes, etc. may produce a lot of gas when they enter the stomach. If you eat more of these foods, it may lead to burping and spitting under the influence of gastric acid secretion and increased gas in the stomach. The symptoms can be relieved by adjusting your diet and eating less of these foods in your daily life. 2. Excessive secretion of stomach acid: If the stomach acid secretion is excessive, burping and spitting may also occur. Symptoms can be relieved by medication, taking oral medication that minimizes the secretion of stomach acid, such as omeprazole, rabeprazole, esomeprazole, and so on. 3. Gastroesophageal Reflux Disease (GERD): There is a high pressure zone at the lower end of the esophagus that prevents reflux of gastric contents, and an imbalance in the functioning of this zone may lead to hiccups and spitting up of acidic water. Symptoms can be relieved by surgical treatment, such as laparoscopic fundoplication. When hiccups and spitting acidic water occur, you should consult a doctor in time, complete physical examination, gastric fluid analysis, esophageal manometry and other tests under the guidance of the doctor, to clarify the cause of the disease, and actively treat it. Drugs need to be used under the guidance of a professional physician, and should not be used arbitrarily on their own.
