what causes yellow color of feces?

The yellow color of feces is primarily caused by the presence of bilirubin, a pigment produced during the breakdown of red blood cells. When bile, which contains bilirubin, is not fully processed by the intestines, it can lead to yellowish stools. Additionally, a diet high in certain foods, such as those rich in fat or certain artificial colors, can also contribute to this coloration. In some cases, yellow feces may indicate a malabsorption issue or other gastrointestinal problems that warrant medical attention.
