welcome to HCM.,
As any mother will be you also seem to be quite apprehensive about the green stool
passed by your child.
the simple reason why a person passes green stool is:
Bile secreted in to the intestines progressively changes color from green to yellow to brown, due to the action of bacteria in the large intestine on the bile salts.
Green stool often indicates that food has passed through the intestines faster than normal (called decreased bowel transit time), before it could be changed from green to brown.
decreases bowel transit time, so any condition that causes diarrhea can result in green stool.
since you are already giving your child nutrolin b , which is a probiotic
with vitamin b complex, it wil help to build up the intestinal microbial flora, which was lost due to diarrhoea
so with in 5 to 7 days or as soon as the normal intestinal microbial flora is built up , your child will start passing the normal brown colour stool.
wishing you and baby health.
