The color of stool in dyspepsia is not fixed, it may be related to the color of food consumed, related to biliary tract diseases, and related to gastrointestinal bleeding.
1. Consumption of food containing pigment: chlorophyll cannot be completely destroyed after consuming a large amount of green vegetables in indigestion, which may lead to greenish stool color; reddish stools after consuming red dragon fruit or red amaranth.
2. Biliary obstruction: Bilirubin in bile will form fecal cholagens when it is discharged to the intestines, and normal stools will be yellow due to the presence of fecal cholagens. Biliary obstruction caused by gallstones and pancreatic tumors will block the discharge of bile, which will make the color of stools become lighter, or even clay-like stools.
3. Intestinal bleeding: a small amount of intestinal bleeding manifested as black stools, bleeding site closer to the anus or intestinal bleeding can be a large amount of fresh blood stools.
When there is a change in the color of the stool, it is not necessarily caused by indigestion, the patient should go to the hospital in a timely manner to improve the examination, to clarify the cause of the disease and then give targeted treatment.
