Mucus is a jelly-like substance that can appear white, clear or yellowish. The lining of the large intestine produces the mucus found in bowel movements. Normal stool may contain small amounts of mucus. Conditions that irritate the lining of the intestine can cause the colon to secrete mucus and water into the bowel, according to the Merck Manuals. All changes in bowel movements or a change in the consistency of stool require further medical evaluation. Reporting mucus in the bowels to a physician is important for proper diagnosis and treatment. Without proper treatment, conditions that cause mucus in stool may become life threatening.
Intussusception
Intussusception is a condition that occurs when a portion of the intestines slides into another section. Food may not pass as normal through this portion of the intestines, and the blood flow may become compromised. If an adequate amount of blood does not reach the intestine, the intestine can die. Intussesception occurs in children more often than adults, especially in children between the ages of 6 months and 2 years, according to MedlinePlus. Symptoms of intussusception include abdominal pain, fever, vomiting and mucus stools. The bowel movements with mucus can also contain blood and resemble currant jelly.
Irritable Bowel Syndrome
Irritable bowel syndrome, also referred to as IBS, affects up to 20 percent of adults in the United States and is more common for women, according to the National Digestive Diseases Information Clearinghouse. This intestinal disorder occurs when individuals have a sensitivity to certain foods and stress. Symptoms of IBS include abdominal pain and bloating. Many individuals experience constipation. When a bowel movement does occur, it may contain mucus. Other individuals experience diarrhea. Modifying the diet may help control the symptoms associated with the condition.
Polyps
Polyps are abnormal growths of tissue that occur in the large intestine. The growths protrude into the space of the intestine and vary in shape and size. Up to 20 percent of the adult population in the United States suffers from these growths. Some polyps occur but cause no signs or symptoms. Other polyps cause bleeding, bowel changes and abdominal pain. Polyps can also cause mucus to appear in a bowel movement. Treatment for polyps in the colon includes a colonoscopy to visualize the growths and remove them. Without treatment, polyps may cause colon cancer, according to the American Society of Colon and Rectal Surgeons.
