Hunger and bloating are mostly seen in indigestion, gastritis or gastric ulcer, intestinal obstruction and so on. 1. Indigestion: mainly refers to functional dyspepsia, food is not digested in time after entering the gastrointestinal tract and produces more gas, so you feel bloated, and then you feel hungry when intestinal peristalsis occurs. 2. Gastritis or gastric ulcer: the patient’s gastric digestive function is affected, the digestive ability is reduced, the food stays for a long time leading to bloating, but due to the abnormal secretion of gastric acid, it will cause some stimulation to the intestinal tract, which triggers the abnormal intestinal peristalsis and feeling hungry. 3. Intestinal obstruction: may be due to intestinal adhesions or intestinal space-occupying lesions, intestinal contents are not able to run normally, the discharge will feel abdominal distension, but the stomach within the normal digestion and absorption will feel hungry. Hunger and bloating may also be caused by other reasons, it is recommended that patients go to the hospital in a timely manner to identify the causes of targeted treatment or therapy.
