What causes green coloured stool in an infant?
Patient: Hi, We recently changed our 2 and half month old daughter s infant formula.Initially it was a lactose free formula and we changed it to one which has lactose. She has started passing yellow-green stool with lots of white curd like residue in it. This did not happen with the earlier brand.It was quite a lot of curd like substance, is there a chance that I might be over feeding her or may be she is intolerant to the lactose/milk protein ? and would it harm her if I continued with that formula feed. Doctor: HI...this is completely normal - DO NOT WORRY. It is very normal for both breast fed and formula fed babies to have such greenish stools and it is definitely not a sign of disease or bacterial infection.Unless the kid's having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. There is no need to use antibiotics unless there is blood in the motion. Antibiotics might worsen if unnecessarily used causing antibiotic associated diarrhoea.Regards - Dr. Sumanth
