Liver Blockage
Iron deficiency can lead to white stool anemia [5], and in extreme cases, it could be a symptom of liver blockage. Chalky grey or white baby poop, as well as pale yellow poop, can often be caused by a liver blockage. Liver cells in your baby produce bile (a liquid that helps in breaking down the body fats). When bile builds up and can’t drain out of the liver as a result of getting trapped due to biliary atresia [6]. Biliary atresia appears when babies are between 2 and 8 weeks old. Other symptoms may be noticed in addition to the white poop. There may be a loss of weight and they tend to cry more than normal. Consult your doctor immediately if a liver block is suspected.
