Hello! Welcome to HealthcareMagic!
I understand your concern. Grey stool can be due to many conditions. It can be due to food, medications, certain diseases, such as gallbladder
I recommend you to do a blood test
and a bilirubin
level, just to rule out the possibility of a high bilirubin.
Hope my answer was helpful. Thank you for the query.
