The sigmoid colon is the S-shaped part of your large intestine, connecting to the rectum. It plays a crucial role in storing and expelling waste from your body. Various diseases can affect the sigmoid colon, impacting your digestive health and overall well-being. This guide explores the anatomy, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, preventions, and answers to common questions about sigmoid colon diseases.
Anatomy of the Sigmoid Colon
Structure
- Location: The sigmoid colon is located in the lower abdomen, forming an S-shape between the descending colon and the rectum.
- Function: It stores fecal wastes until they are ready to be expelled from the body during bowel movements.
- Length: Typically about 40 centimeters long.
Blood Supply
- Superior Rectal Artery: Supplies blood to the upper part of the sigmoid colon.
- Middle and Inferior Rectal Arteries: Supply the lower sections, ensuring the colon receives adequate nutrients and oxygen.
Nerve Supply
- Autonomic Nervous System: Controls involuntary movements and functions.
- Inferior Mesenteric Plexus: Provides nerve fibers that regulate the sigmoid colon’s activity, including muscle contractions for bowel movements.
Types of Sigmoid Colon Diseases
