Should You Worry About Green Poop

Stool turns green in colour due to several reasons, especially in children. In general, the stool colour is brown, but it may turn into red, black, yellow or green.

Green coloured faeces may be normal in a few cases, especially in the breastfed infants but may also be a sign of bacterial infection. The stool colour is due to bile. Bile is a yellow, green fluid produced in the liver that aids food digestion.

Digestive juices break down the foods that pass through the intestine and renders different shades of brown stool. However, if you eat foods high in chlorophyll such as kale or spinach, suffer from bacterial infection, or take antibiotic, the colour of stool changes into green. In most cases, green stool is not a matter of concern, but it is better to explore and acknowledge the reasons behind.
