Neonatal bloating is characterized by decreased milk intake, vomiting, abdominal distension, irritability and crying, and can be relieved by massaging the abdomen, keeping warm and adjusting feeding patterns. Neonatal bloating can be categorized into two main causes: excessive air intake and decreased exhaustion. If there is too much air in the bottle nozzle during artificial feeding or if the child cries too much, this can lead to an increase in gas entering the gastrointestinal tract. When the child has gastrointestinal dysfunction or intestinal infection, obstruction, intestinal peristalsis exhaust function is weakened, can also lead to gas accumulation caused by abdominal distension. You can massage the newborn’s abdomen clockwise to promote intestinal peristalsis and increase the exhaust; newborns have fragile gastrointestinal function, avoiding cold leads to weakening of digestive function; pay attention to the angle of tilt of the bottle when bottle feeding, and pay attention to the burp after feeding, all can avoid bloating. If the above methods still can not alleviate the bloating, you can follow the doctor’s advice to apply probiotics (such as bacillus subtilis bacillus granules) and other medications. The causes of abdominal distension in newborns are different. If the above methods cannot relieve abdominal distension, or if there is drowsiness or obvious irritability, you should consult a doctor in time to avoid delaying your condition.
