A small amount of mucus in the stool is normal, but a large amount can be a sign of illness.
Mucus serves important functions in the intestines, such as fighting bacteria, being involved in the digestive enzymes and acids, and helping to eliminate stool from the body.
You should pay attention to the following symptoms:
- Increased amount of mucus;
- Blood in the stool;
- Abdominal pain, cramping, or bloating;
- A sudden change in the color, frequency, or consistency of your stool.
Mucus in the stool may be caused by the following diseases:
- Crohn's disease;
- Ulcerative colitis;
- Irritable bowel syndrome;
- Intestinal infection;
- Colorectal cancer;
- Proctitis.
