Eating very little and still always burping may be caused by physiological factors, but also may be caused by chronic gastritis, esophageal hiatal hernia, gastrointestinal neurosis and other pathological factors. 1. Physiological factors: eating too fast, resulting in too much gas into the human stomach, so the gas will be discharged out of the body through burping. Or some people will drink too much carbonated beverages, such as Coke or Sprite, which will produce more gas after intake into the stomach, so there is the phenomenon of hiccups even though you eat very little. 2. Chronic gastritis: gastritis hiccup is due to improper diet or Helicobacter pylori infection, mucosal lesions caused by gastrointestinal insufficiency, stimulate the diaphragm spasms, which in turn causes the phenomenon of eating very little and always hiccup. 3. Esophageal hiatal hernia: Esophageal hiatal hernia refers to abdominal organs, such as a part of the stomach herniated into the diaphragm through the parietal hernia of the esophagus, which can stimulate the diaphragm and lead to hiccups, and thus the phenomenon of hiccups always occurs when you eat very little. 4. Gastrointestinal neurosis: in patients with gastrointestinal neurosis, gastrointestinal peristalsis is weakened, causing diaphragmatic spasm and hiccups. Under the guidance of a doctor, you can use psychotropic drugs and intestinal probiotics to regulate the microenvironment of the gastrointestinal tract, and you can also accept the professional treatment of psychologists. If the patient eats very little and always hiccups may also be pyloric spasm, reflux esophagitis and other factors, it is recommended that the patient seek medical attention in a timely manner to identify the cause of the targeted treatment.
