Children’s green poop may be related to physiological reasons such as consuming a lot of green vegetables, or pathological reasons such as enteritis and intestinal flora imbalance. 1. Physiological reasons: when children eat too much green vegetables and other foods containing green pigment, it can cause green poop. 2. Pathological reasons: due to improper diet, extra-intestinal infections and other pathogens such as Staphylococcus aureus and invasive Escherichia coli can cause intestinal infections and enterocolitis, leading to green poop; long-term application of antibiotics can also cause intestinal bacterial flora imbalance, leading to green poop. When a child has green poop without any obvious cause and has diarrhea, abdominal pain and other abnormal symptoms, he should consult a doctor in time, under the guidance of the doctor to clarify the cause, so as to actively treat it.
