Why do i have yellow bile in my stool?

Your post is confusing. Bile is the color producing agent in stool, starting out ultra-green and transitioning through yellows to brown depending on the action of enzymes and bacteria in the poop. Yellow poop has just gone through before browning. By itself the color has no significance/is normal.

We all do. It is normal. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines
