Suffering from gastritis and not feeling full may be caused by excessive stomach acid, gastrointestinal dysfunction, and damage to the gastric mucosa. 1. Excessive gastric acid: inflammation of the stomach will stimulate the cells in the stomach to secrete more gastric acid, gastric acid will digest the food into the stomach faster, so part of the gastritis patients will not feel full. 2. Gastrointestinal dysfunction: Due to gastrointestinal dysfunction, the peristaltic ability of the intestines and stomach is weakened, which leads to the accumulation of food in the stomach for a long period of time, thus resulting in an abnormal feeling. The ability to perceive the stomach will be weakened, and there will be a situation that you can’t feel satiety after eating and drinking. 3. Damage to the gastric mucosa: under the influence of gastritis, the gastric mucosa of the patient is damaged, which in turn affects the patient’s perceptual nerves, so that the patient does not feel a sense of satiety after eating. If the patient is accompanied by other uncomfortable symptoms, it is recommended that the patient go to the hospital in time.
