Full-month infant intestinal flatulence may be caused by indigestion, intestinal obstruction, etc. It can be treated by topical corkscrew, oral medication, abdominal massage, etc., and if necessary, timely consultation. Most of the flatulence in full-month babies is caused by indigestion. If the baby is not defecated for more than 4 days, probiotics such as bifidobacteria can be used to regulate the intestinal tract, and if necessary, corkscrew can be inserted into the anus for laxative treatment. In addition, before breastfeeding, you can give your baby 3 to 4 times of gentle abdominal massage to promote intestinal peristalsis and relieve flatulence. If the baby’s flatulence is still not relieved, or accompanied by vomiting, it is considered intestinal obstruction and should be sent to the hospital for emergency treatment. Parents are advised to seek prompt medical attention to identify the cause of intestinal flatulence in full-month-old babies and to treat the condition actively. The above medications should be used in accordance with medical advice.
