The feeling of stomach acidity, bloating and heartburn after drinking may be related to factors such as alcohol stimulation of gastric mucosa, excessive secretion of gastric acid and relaxation of cardia sphincter.
1. Alcohol stimulates the gastric mucosa: After alcohol enters the stomach, it can directly stimulate the gastric mucosa, resulting in gastric mucosal congestion, edema, and also cause vasodilatation under the mucosa. Gastrointestinal digestion and absorption function becomes poor, will feel bloating, stomach acid. Excessive secretion of gastric acid can cause reflux and heartburn.
2. Excessive secretion of gastric acid: Alcohol promotes the secretion of gastric acid and pepsin, and the excessive secretion of gastric acid aggravates the congestion and edema of gastric mucosa, and pepsin can digest its own gastric mucosa, and there is damage to the gastric mucosa, which can cause gastric distension, gastric acid, and heartburn sensation.
3. Cardia sphincter relaxation: under normal circumstances, cardia sphincter is closed to prevent gastric contents from flowing back into the esophagus, and it will be relaxed only when eating. Excessive alcohol consumption can lead to stomach distension. Alcohol can cause the cardia sphincter to relax, allowing highly acidic stomach contents to flow back into the esophagus, causing stomach acidity and heartburn.
Feeling sour stomach, bloating and heartburn after drinking alcohol may also be caused by other reasons, and it is recommended that patients go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
