Green stools in infants may be a normal physiological phenomenon, or it may be caused by abdominal cold, indigestion and other reasons. 1. Normal physiological phenomenon: Consider that it may be caused by the infant’s recent consumption of a large number of foods containing green pigments, such as kiwifruit, green vegetables, etc., which may lead to an increase in chlorophyll in the gastrointestinal tract, resulting in the phenomenon of green stools. 2. Abdominal cold: when the baby’s abdomen is cold, it is easy to lead to the weakening of the digestive ability of the intestinal tract, resulting in a decrease in the consumption of bile, resulting in excess bile along with the discharge of stools, thus showing the phenomenon of green stools, which may be accompanied by abdominal distension, abdominal pain and other discomforts. 3. Indigestion: Since the development of the gastrointestinal system of infants is not yet perfect, if parents do not feed properly, feed too much milk at one time, or feed frequently, it is easy to lead to indigestion of infants, which may lead to the phenomenon of green stools, and may be accompanied by abdominal distension and pain and other discomforts. Green stools in infants may also be caused by other reasons, if accompanied by obvious symptoms of discomfort, you should take your baby to the doctor as soon as possible.
