Sigmoid colon pain can be uncomfortable and concerning. This guide breaks down everything you need to know about it in simple terms. From anatomy and causes to treatments and prevention, we’ve got you covered.
The sigmoid colon is the S-shaped last part of the large intestine, connecting the descending colon to the rectum. It plays a crucial role in storing fecal wastes until they are ready to be expelled from the body.
Anatomy of the Sigmoid Colon
Structure
- Location: Situated in the lower left abdomen.
- Shape: S-shaped, which allows flexibility and movement.
- Function: Absorbs water and salts from waste material and forms stool.
Blood Supply
- Artery: Supplied primarily by the superior rectal artery, a branch of the inferior mesenteric artery.
- Veins: Drains into the superior rectal veins, then to the inferior mesenteric vein, and eventually to the portal vein.
Nerve Supply
- Autonomic Nervous System: Controlled by the sympathetic and parasympathetic nerves.
- Function: Regulates muscle contractions and secretions, aiding in the movement of stool.
Types of Sigmoid Colon Pain
- Sharp Pain: Sudden and intense.
- Dull Ache: Persistent and mild to moderate.
- Cramping: Intermittent and may coincide with bowel movements.
- Burning Sensation: May indicate inflammation or infection.
- Radiating Pain: Spreads to other areas like the lower back or pelvic region.
Common Causes of Sigmoid Colon Pain
