Lower rectum piles, commonly known as hemorrhoids, are swollen and inflamed veins in the lower rectum and anus. They can cause discomfort, pain, and bleeding, affecting daily activities and quality of life. Understanding hemorrhoids—their anatomy, types, causes, symptoms, diagnostics, treatments, prevention, and when to seek medical help—can empower you to manage and prevent this common condition effectively.
Anatomy of the Lower Rectum and Hemorrhoids
Structure
The lower rectum and anus consist of blood vessels, nerves, muscles, and connective tissues. Hemorrhoids are swollen veins located in this area. They can develop inside the rectum (internal hemorrhoids) or under the skin around the anus (external hemorrhoids).
Blood Supply
Hemorrhoids receive blood through branches of the superior and inferior rectal arteries. Internal hemorrhoids are supplied by the superior rectal artery, while external hemorrhoids are supplied by the inferior rectal artery.
Nerve Supply
The anal region is richly innervated by the inferior rectal nerves (a branch of the pudendal nerve) for external hemorrhoids and the superior rectal nerves for internal hemorrhoids. This nerve supply is why hemorrhoids can be painful or cause a sensation of itching.
Types of Hemorrhoids
- Internal Hemorrhoids: Located inside the rectum, usually painless but may cause painless bleeding during bowel movements.
- External Hemorrhoids: Found under the skin around the anus, can cause pain, swelling, and itching.
- Thrombosed Hemorrhoids: Occur when a blood clot forms inside an external hemorrhoid, leading to severe pain and swelling.
- Prolapsed Hemorrhoids: Internal hemorrhoids that protrude through the anus, which can be painful and may require manual reduction.
