After a bout of gastroenteritis (gastro), poo can vary in color. It may appear green, yellow, or even tan due to a quicker transit time through the intestines, which can prevent bile from breaking down completely. If unusual colors persist, especially black or red, it’s important to consult a healthcare professional.
