What causes green and frequent bowel movements in newborns?

Possible reasons for green and frequent stools in newborns may include the following: 1. Digestive factors: Rapid intestinal motility in newborns may cause bile to be excreted in stool before being fully digested, resulting in green-colored stools. This may be related to factors such as a cold abdomen or indigestion. 2. Lactose intolerance: If a newborn is lactose intolerant, undigested lactose may ferment in the intestine and produce gas, potentially leading to green and more frequent stools. 3. Hunger state: When a newborn is hungry, increased gastrointestinal motility may cause bilirubin in the intestines to be excreted in stool before conversion, resulting in green, scanty stools. 4. Maternal diet: If the mother consumes large amounts of leafy green vegetables, this may affect the color of the newborn's stool through breast milk, causing it to appear green.
