Patient's question:
The baby has been having dark green bowel movements since the second month and it's still the same now. The baby is currently 4.5 months old and is fed with formula milk, having one bowel movement a day.Doctor's answer:
Your baby's green stool has two possible reasons. One reason is poor bile excretion, which is caused by excessive intestinal motility. The bilirubin is not fully excreted before being expelled from the body, resulting in green stool. The other reason is hunger-induced nausea and vomiting. In this case, the nausea and vomiting last for a long time, and parents are hesitant to feed the baby more. Due to hunger, the baby may have green stool. It could be caused by the formula they are consuming. You can try switching to a different formula to see if it improves. If it does, then the issue is likely with the formula.
