Large Intestine Disorders

The large intestine, also known as the colon, plays a crucial role in your digestive system. Understanding its anatomy, the various disorders that can affect it, their causes, symptoms, diagnostic methods, treatments, and prevention strategies is essential for maintaining good health. This guide breaks down everything you need to know about large intestine disorders in simple, easy-to-understand language.

Anatomy of the Large Intestine

Understanding the structure of the large intestine helps in comprehending how various disorders affect it.

Structure

The large intestine is the final part of the digestive system, responsible for absorbing water and salts from the remaining food matter and storing waste until it is expelled from the body. It consists of several parts:

1. Cecum: The starting point, located in the lower right abdomen.
2. Ascending Colon: Travels upward on the right side.
3. Transverse Colon: Crosses the abdomen from right to left.
4. Descending Colon: Travels downward on the left side.
5. Sigmoid Colon: S-shaped section leading to the rectum.
6. Rectum: Stores stool before it is expelled.
7. Anus: The opening through which stool leaves the body.

Function

• Water Absorption: Extracts water from undigested food.
• Electrolyte Balance: Maintains levels of salts and minerals.
• Formation and Storage of Feces: Compacts waste for elimination.
• Bacterial Flora: Hosts beneficial bacteria aiding digestion.

Types of Large Intestine Disorders

Large intestine disorders can affect different parts and functions of the colon. Here are the primary types:

1. Inflammatory Bowel Disease (IBD):
   • Crohn’s Disease: Can affect any part of the gastrointestinal tract.
   • Ulcerative Colitis: Affects only the colon and rectum.
2. Irritable Bowel Syndrome (IBS):
   • A functional disorder causing abdominal pain and altered bowel habits.
3. Diverticular Disease:
   • Diverticulosis: Formation of small pouches in the colon.
   • Diverticulitis: Inflammation or infection of these pouches.
4. Colon Cancer:
   • Malignant growths in the colon or rectum.
5. Constipation:
   • Difficulty in passing stool regularly.
6. Diarrhea:
   • Frequent loose or watery stools.
7. Hemorrhoids:
   • Swollen blood vessels in the rectum or anus.
8. Colon Polyps:
