Stomach pain without farting may be caused by gastroenteritis, gastric ulcer, intestinal obstruction and so on. 1. Gastroenteritis: generally due to dietary impurity, overeating and other factors caused by inflammatory changes in the mucosa of the gastrointestinal tract, the gastrointestinal tract at this time to the food digestion and absorption is not complete, resulting in the accumulation of food residues, resulting in gas can not be discharged and cause abdominal distension, abdominal pain and other symptoms, the symptoms of stomach pain without farting. 2. Gastric ulcer: when the gastric mucous membrane is damaged and broken, ulcers are easily formed, and stomach pain will occur, mostly after meals. The digestive tract does not digest and absorb the food thoroughly, resulting in the accumulation of food residue, and the gas produced cannot be discharged. Therefore, the symptoms of stomach pain without farting appear. 3. Intestinal obstruction: when there is an intestinal obstruction, the intestinal peristalsis will be accelerated, and the food residues and feces before the obstruction site can not be transported downward, resulting in the accumulation of the feces after the obstruction site can be discharged normally, but will not produce new gas, which will lead to the symptom of stomach ache without farting. It is recommended to go to the hospital immediately for early diagnosis and treatment of the above symptoms to avoid delay.
