The greenish color of stool may be related to the food intake, indigestion, cholestatic jaundice and other reasons. 1. Food intake: green vegetables have high chlorophyll content, such as cabbage, mustard, rape, etc. If the patient consumes too much green food, it cannot be fully digested, which may lead to greenish-green stool. 2. Indigestion: because the abdomen is cold or after eating cold food can cause indigestion phenomenon, which leads to stool green color. 3. Cholestatic jaundice: Cholestatic jaundice is a kind of hepatobiliary disease caused by various reasons, which leads to bile secretion and excretion obstacles, resulting in abnormal bilirubin metabolism. Cholestatic jaundice is mainly due to impaired liver function or bile excretion pathway obstacles, resulting in bile stasis, which causes the phenomenon of greenish-green stools. When the patient has greenish-green stools, it is recommended that the patient actively consult a doctor to clarify the cause of the disease and standardize the treatment.
