Patient's question:
7 days ago, the baby's stool was light blue and had a sour smell. After changing the formula, the stool has turned yellow, but sometimes it has bubbles, sometimes it has particles, but all of them have a sour smell. Is it because the formula is too concentrated?Medical history and treatment effectiveness: The baby is 7 days old and has been on formula for two months. The stool was light blue and had a sour smell a few days ago. After changing the formula, the stool has turned yellow, but sometimes it has bubbles, sometimes it has particles, but all of them have a sour smell. Is it because the formula is too concentrated?
Doctor's answer:
The stool color of a newborn baby may be yellow, green, or even dark green, which is normal. This is due to differences in the milk formula consumed. The following stool colors require more attention: (1) Lighter colors are more concerning, such as pale yellow or off-white, which may indicate abnormal bile excretion, (2) Passing black stool may suggest upper gastrointestinal bleeding, and (3) Passing red stool could indicate lower gastrointestinal bleeding.
