Symptoms of intestinal flatulence in infants mainly include abdominal bulging, excessive anal discharge, spitting up, shortness of breath, crying and so on. 1. Abdominal bulging: due to the accumulation of a large amount of gas in the infant’s intestinal tract, which cannot be discharged in a timely manner, and then there will be a bulging of the abdomen. 2. More anal discharge: due to the excessive accumulation of gas in the intestines, it will lead to rumbling in the baby’s stomach, and there will also be an increase in anal discharge. 3. Spitting up: Infants with flatulence may experience abdominal pain when feeding and may spit up after a few mouthfuls of milk. 4. Shortness of breath: If the flatulence presses on the baby’s diaphragm, shortness of breath or even difficulty in breathing may occur. 5. More than crying: flatulence will cause discomfort to the infant, so more than crying will occur. If infants have the above symptoms, parents are advised to bring their children to the doctor in time to avoid delay in treatment.
