Green stools are very common in babies. Some causes of green stools need to be treated, some do not, and most may not require treatment, but they need to be identified as to what is causing them and then treated symptomatically. Most babies have green poop because the food is not fully digested, which is what we usually call indigestion. Then, we have to find the cause of indigestion, for example, some babies are in the cold, will also lead to green stool, because the cold will lead to for intestinal peristalsis to speed up, when biliverdin is too late to also turn into bilirubin, there will be green stool situation. There are also times when the food is not digested well, such as indigestion caused by eating a lot of meat, may also make the stool green. The color of some foods can also have an effect on the stool, so more experience will need to be summed up. If your child’s stool often turns green for a long time, or if it is accompanied by discomfort such as abdominal pain and diarrhea, unsatisfactory growth and weight gain, etc., you need to go to the doctor promptly.
