Baby’s flatulence and stomach pain when he eats may be caused by mechanical intestinal obstruction, gastrointestinal dysfunction, etc., which can be treated by etiologic treatment, medication and surgery. 1. Mechanical intestinal obstruction: the gas and liquid reabsorption and excretion in the proximal intestinal tube are obstructed, and the bacteria in the intestinal tube produce a large amount of gas due to the change of the intestinal environment, and abdominal distension occurs. At this time, early diagnosis and surgery must be performed to relieve the obstruction. 2. Gastrointestinal dysfunction: children can be treated with probiotics such as Clostridium typhimurium, Saccharomyces boulardii and omeprazole as prescribed by the doctor. All of the above drugs need to be used under the guidance of a doctor, avoid self-medication. There may be other reasons for your baby’s flatulence when he eats, so we recommend that you consult a doctor to determine the cause of your baby’s flatulence, and then give him or her targeted treatment.
