The large intestine is the final section of the digestive system, responsible for absorbing water and electrolytes from indigestible food matter and forming solid waste (stool) for excretion. It is about 5 feet long and consists of four main parts:
- Cecum: The beginning of the large intestine, where the small intestine empties.
- Colon: The largest section, which has four parts:
- Ascending colon: Moves upward on the right side.
- Transverse colon: Runs across the body.
- Descending colon: Moves downward on the left side.
- Sigmoid colon: Connects the descending colon to the rectum.
- Rectum: Stores stool until it is expelled.
- Anus: The opening through which waste exits the body.
Types of Large Intestine Diseases
Large intestine diseases refer to any conditions affecting this part of the digestive system. These can range from mild to severe and include:
- Irritable Bowel Syndrome (IBS): A disorder causing abdominal pain, bloating, and changes in bowel movements.
- Ulcerative Colitis: A chronic condition causing inflammation and sores (ulcers) in the colon lining.
- Diverticulosis: Small pouches form in the walls of the colon, which can become inflamed (diverticulitis).
- Colon Polyps: Abnormal growths in the colon lining that can become cancerous over time.
- Colorectal Cancer: Cancer of the colon or rectum, often arising from polyps.
- Crohn’s Disease: A type of inflammatory bowel disease (IBD) that can affect any part of the gastrointestinal tract, including the large intestine.
- Constipation: Difficulty in passing stool, leading to infrequent bowel movements.
- Diarrhea: Frequent, watery bowel movements often caused by infection or irritation.
- Hemorrhoids: Swollen veins in the lower rectum or anus.
- Colonic Ischemia: Reduced blood flow to the colon, leading to inflammation and damage.
Causes of Large Intestine Diseases
- Genetics: Some diseases, like Crohn’s disease and colorectal cancer, run in families.

Frequently Asked Questions (FAQs)
1. What is the difference between the large and small intestine?
The large intestine absorbs water and forms stool, while the small intestine absorbs most nutrients from food.
2. Can diet affect large intestine health?
Yes, a high-fiber diet promotes regular bowel movements, while processed foods can increase the risk of colon diseases.
3. What are colon polyps?
Colon polyps are abnormal growths on the colon lining that can develop into cancer over time.
4. How is colorectal cancer detected?
Through screening tests like colonoscopy, which can identify polyps and early cancer signs.
5. What is the treatment for IBS?
Treatment may include dietary changes, stress management, and medications to relieve symptoms.
6. Can large intestine diseases be prevented?
Many can be prevented through a healthy diet, regular exercise, avoiding smoking, and regular medical screenings.
7. What causes diverticulosis?
Diverticulosis is caused by weakened areas in the colon wall forming small pouches, often due to a low-fiber diet.
8. Is hemorrhoid surgery necessary?
Not always. Most hemorrhoids can be treated with lifestyle changes and medications, but severe cases may require surgery.
