Eating a meal in the stomach clogging difficult, may be caused by gastrointestinal tract dysfunction, chronic gastritis, gastric ulcer and other reasons. 1. Gastrointestinal tract dysfunction: when eating too much food or after eating hard-to-digest food, it will increase the burden on the gastrointestinal tract and make the gastrointestinal tract dysfunctional, leading to indigestion and the symptom of bloating after eating. 2. Chronic gastritis: gastric acid stimulates the gastric mucosa, and damage to the gastric mucosa affects gastric peristalsis, so that food piles up in the stomach and gas from food accumulates in the stomach, which stimulates the gastric mucosal nerves and causes bloating. 3. Gastric ulcer: the gastric mucosa is attacked by pepsin, resulting in localized inflammatory damage, leading to the emergence of peptic ulcer. The ulcers can easily block the discharge of gastric contents and gases, thus producing the symptoms of gastric distension. People who suffer from bloating after eating can go to the hospital for gastroscopy and other relevant examinations to clarify the cause of the disease and then be treated under the guidance of the doctor.
