Hemorrhoids, often referred to as piles, are swollen veins in the lower rectum or anus. They can cause discomfort, pain, and bleeding. This guide provides a detailed overview of external rectal venous plexus hemorrhoids, covering their anatomy, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention strategies, when to seek medical help, and frequently asked questions (FAQs)
Hemorrhoids are swollen blood vessels located around the anus or in the lower rectum. They are similar to varicose veins that can occur in the legs. Hemorrhoids can be internal (inside the rectum) or external (under the skin around the anus). This guide focuses on external hemorrhoids, specifically those involving the external rectal venous plexus.
Anatomy of External Rectal Venous Plexus Hemorrhoids
Structure
The external rectal venous plexus consists of a network of veins located just beneath the skin around the anus. These veins can become swollen and inflamed, leading to the formation of external hemorrhoids.
Blood Supply
External hemorrhoids receive blood through the inferior rectal arteries, which are branches of the internal pudendal arteries. Blood drains from these hemorrhoids via the inferior rectal veins into the internal iliac veins.
Nerve Supply
The area around the anus is rich in nerve endings, making hemorrhoids sensitive to pain and discomfort. The nerves in the external rectal venous plexus can cause significant pain when hemorrhoids become swollen or irritated.
Types of Hemorrhoids
Hemorrhoids are categorized based on their location and appearance:
- Internal Hemorrhoids: Located inside the rectum, usually painless but can cause bleeding.
- External Hemorrhoids: Located under the skin around the anus, often painful and may bleed.
- Prolapsed Hemorrhoids: Internal hemorrhoids that have stretched and bulged outside the anus.
- Thrombosed Hemorrhoids: Hemorrhoids with a blood clot inside, causing severe pain and swelling.
Causes of External Hemorrhoids
External hemorrhoids can develop due to various factors that increase pressure on the veins around the anus and rectum. Here are 20 common causes:
- Straining During Bowel Movements: Excessive pressure can enlarge the veins.
- Chronic Constipation: Frequent straining leads to hemorrhoid formation.
- Diarrhea: Repeated episodes can irritate the anal area.
