A bloated stomach after eating something may be caused by gastric neurosis, indigestion, chronic gastritis, peptic ulcer, gastric ptosis and other reasons. 1. Gastric neurosis: stress, tension, anxiety, etc. lead to the triggering of gastric neurosis, resulting in abnormal gastric peristalsis, affecting the digestion of food, and the symptoms of bloating when eating something. 2. Indigestion: the stomach peristalsis is slow, the secretion of digestive juices is reduced, and the food in the stomach can not be emptied in a timely manner, so the stomach feels bloated when you eat a little bit of food, accompanied by nausea, loss of appetite and other symptoms. 3. Chronic gastritis: for example, superficial gastritis, erosive gastritis, etc., because of the relatively weak digestive ability, so eat a little something feels bloated, accompanied by acid reflux, nausea, belching and other symptoms. 4. Peptic ulcer: the protective barrier of the gastric mucosa is destroyed, the presence of ulcers affects the digestion and absorption of food, so eat a little bit of food feels bloated, accompanied by acid reflux, heartburn, nausea, stomach pain and other symptoms. It is recommended to consult a doctor in a timely manner to identify the cause and follow the doctor’s instructions, so as not to delay the condition.
