Gastritis patients who always want to eat may be caused by gastrointestinal nerve dysfunction, increased gastric acid secretion and decreased gastric motility. Gastritis patients with gastrointestinal nerve dysfunction may lead to an increase in appetite and are also prone to indigestion symptoms. Secondly, when the inflammation continuously causes irritation to the mucosa of the stomach, it will increase the secretion of gastric acid, which makes the patient want to eat, and is also prone to symptoms such as acidity in the stomach and stomach pain. In addition, the gastric power of gastritis patients will be reduced, the food in the stomach will stay in the stomach for a long time, and the nutrients in the food can not be digested in time, which may lead to malnutrition in the patient’s body, so that they want to supplement the nutrients by eating frequently. Some gastritis patients may also experience symptoms such as bloating, lack of desire to eat, acid reflux in the stomach, and abdominal pain. It is recommended that gastritis patients adjust their dietary habits, eat small meals and avoid smoking and alcohol or eating cold, spicy and irritating foods to minimize the damage to the mucous membrane of the stomach. At the same time, go to the hospital to follow the doctor’s instructions for professional treatment, avoid delaying the condition, otherwise it may lead to further development of the disease, affecting health.
