Purple poop may be caused by diet, acute gastric mucous membrane bleeding, intestinal cancer and other reasons.
1. Diet: If the patient has recently eaten some purple food, such as purple potato, dragon fruit, purple kale and so on. As the pigment of this kind of food can not be fully absorbed, it may be accompanied by purple color in the stool.
2. Acute gastric hemorrhage: When gastric hemorrhage occurs, the blood will be discharged from the stomach to the small intestine. However, as the blood cannot be absorbed by the small intestine, the blood becomes purple after oxidization, and will be purple after being excreted with the stool.
3. Bowel cancer: Bowel cancer is caused by the cancer cells in the intestines invading the intestinal wall, which makes the blood circulation of the intestines blocked, and the feces will rub the intestinal wall when it is discharged, and the cancer cells in the intestinal wall will bleed by the friction, and the blood will turn purple after oxidized and discharged.
For patients who have purple stools, they should go to the hospital for gastrointestinal checkups in a timely manner, and it is not recommended to delay the disease.
