Hiccups and heartburn can be caused by the following conditions: 1. Cholecystitis: When the contraction capacity of the gallbladder is weakened, bile secretion will be reduced, so food entering the stomach will lead to hiccups and heartburn. If bile refluxes into the stomach, the bile salts in the bile will react with gastric acid and damage the gastric mucosa, causing gastric ulcers and stomach pain. 2. Gastritis: In addition to burping and heartburn, it can also cause epithelial damage, mucosal inflammation, abdominal pain and bloating. 3. Gastric ulcers: Burping and heartburn are the first symptoms of gastric ulcers and can also lead to abdominal pain, which is strong within one hour after a meal and relieved after two hours. 4. 4.Eating stimulating foods: such as wine and chili peppers, these foods can lead to excessive secretion of gastric acid and relaxation of the sphincter, which can lead to hiccups and heartburn, and sometimes eating too much can also lead to hiccups and heartburn.
