What Are Colorectal Disorders?

The colon is responsible for removing water and electrolytes from partially digested food and helping to excrete solid wastes. Colorectal disorders are a few of the many types of gastrointestinal (GI) conditions that affect the digestive system. Some examples of colorectal disorders include:

Irritable bowel syndrome (IBS)

Irritable bowel syndrome is one of the most common colorectal disorders that affect the gastrointestinal tract. IBS typically causes abdominal pain, accompanied by frequent changes in bowel routine and movement. IBS can be triggered by stress, an episode of food poisoning or can be related to certain food types.

Inflammatory bowel diseases (IBD)

Inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis are chronic inflammatory conditions of the intestinal tract, characterised by abdominal pain, blood in stools and diarrhoea.

Crohn’s disease can affect stomach, small intestines and colon, while ulcerative colitis mainly affects the colon and rectum.

Colon polyps

Colon polyps are growths of tissue that develop from the inner lining of the colon and bulges out into the colon. Most small polyps are often non-cancerous but if left alone over time may grow and mutate into cancer.

Colorectal cancer

Colorectal cancer is a type of cancer that develops in the large intestine or rectum. Colorectal cancer typically begins when healthy cells in the inner walls of the colon or rectum grow into small, non-cancerous polyps. If left untreated or removed, these polyps may develop into cancer.
