Sigmoid colon dysfunction refers to problems affecting the sigmoid colon, a key part of your large intestine. This guide breaks down everything you need to know about this condition, including its anatomy, types, causes, symptoms, diagnostic methods, treatments, and more—all explained in simple,
Anatomy of the Sigmoid Colon
Structure
The sigmoid colon is the S-shaped final part of the large intestine, connecting the descending colon to the rectum. It’s responsible for storing fecal wastes until they’re ready to be expelled.
Blood Supply
The sigmoid colon receives blood primarily from the sigmoid arteries, branches of the inferior mesenteric artery. Proper blood flow is crucial for its function and health.
Nerve Supply
Nerves that control the sigmoid colon come from the autonomic nervous system, specifically the parasympathetic fibers via the inferior mesenteric plexus. These nerves regulate movements and secretions within the colon.
Types of Sigmoid Colon Dysfunction
- Irritable Bowel Syndrome (IBS): Causes cramping, abdominal pain, bloating, gas, and diarrhea or constipation.
- Diverticulitis: Inflammation or infection of small pouches in the sigmoid colon.
- Colon Cancer: Malignant growths in the sigmoid colon can disrupt its normal function.
- Constipation: Difficulty in passing stools can lead to sigmoid colon blockage.
- Hirschsprung’s Disease: A congenital condition affecting nerve cells in the sigmoid colon.
- Ischemic Colitis: Reduced blood flow to the sigmoid colon causes inflammation.
- Inflammatory Bowel Disease (IBD): Includes Crohn’s disease and ulcerative colitis affecting the sigmoid region.
- Sigmoid Volvulus: Twisting of the sigmoid colon leading to obstruction.
- Polyps: Noncancerous growths that can develop into cancer.
- Functional Bowel Disorders: Problems with how the sigmoid colon works without any structural issues.
