Gastroesophogeal reflux disease, commonly referred to as GERD, may be a cause of yellow stools. Individuals who suffer from GERD digest food more rapidly than people without GERD. Digested food enters the gastrointestinal tract with a green color. As food moves through the gastrointestinal tract, it absorbs fats and bacteria and, when finally excreted from the system, it is brown in color. If food moves too rapidly through the system, it is unable to absorb these fats and bacteria and a yellow color results.
