Anal canal piles, also known as hemorrhoids, are swollen blood vessels in the lower rectum or anus. Hemorrhoids are common and can cause discomfort, itching, or bleeding. This guide covers everything from their anatomy to treatments, helping you understand them better in simple terms.
Anatomy of the Anal Canal and Hemorrhoids
The anal canal is the final part of the digestive system, measuring about 4 cm in length. It connects the rectum to the outside of the body and allows waste (stool) to exit during a bowel movement.
Structure
The anal canal consists of:
- Internal anal sphincter: This muscle remains tight to keep stool inside until you’re ready to pass it.
- External anal sphincter: This muscle helps control the release of stool.
- Mucosal lining: The inside is lined with tissue that helps ease the stool’s passage.
- Blood vessels: Veins surround the anal canal and can become swollen, forming piles (hemorrhoids).
Blood Supply
The anal canal gets its blood from:
- Superior rectal artery
- Middle rectal artery
- Inferior rectal artery
Nerve Supply
The anal canal is innervated by:
- Somatic nerves for the external area (voluntary control).
- Autonomic nerves for the internal area (involuntary control).
Types of Hemorrhoids (Piles)
There are two main types of hemorrhoids:
- Internal hemorrhoids: These occur inside the rectum and are usually painless, though they can cause bleeding.
- External hemorrhoids: These occur under the skin around the anus and can cause pain, swelling, and irritation.
Another subtype includes:
- Thrombosed hemorrhoids: These are external hemorrhoids that have developed a blood clot, causing severe pain and swelling.
Causes of Hemorrhoids
- Chronic constipation
- Straining during bowel movements

Diagnostic Tests for Hemorrhoids
Doctors use the following tests to diagnose hemorrhoids:
- Physical exam (visual inspection)
- Digital rectal exam (finger examination)
- Anoscopy (viewing the anal canal)
- Proctoscopy (viewing the rectum)
- Colonoscopy (examining the colon for other issues)
- Sigmoidoscopy (examining the lower colon)
- Ultrasound (to check blood flow)
- MRI (for detailed images of tissues)
- CT scan (for cross-sectional images)
- Complete blood count (CBC)
- Fecal occult blood test (FOBT)
- Stool sample test
- Hemorrhoid grading (from I to IV based on severity)
- Anorectal manometry (measuring muscle tone)
- Endoscopy (using a small camera)
- Pelvic MRI
- Rectal biopsy (in rare cases)
- Doppler ultrasound (to assess blood flow in hemorrhoidal vessels)
- Defecography (an X-ray to study bowel function)
- Venogram (examines veins for clots)
Non-Pharmacological Treatments for Hemorrhoids
- Increase fiber intake (fruits, vegetables, and whole grains)
- Drink plenty of water
- Regular exercise
- Avoid straining during bowel movements
- Warm sitz baths (soaking the anal area)
- Use of cold compresses to reduce swelling
- Maintain good hygiene (clean gently after bowel movements)
- Avoid long periods of sitting
- Use moist towelettes or soft tissue for cleaning
- Wear loose-fitting clothing and cotton underwear
- Use a donut cushion for sitting
- Apply witch hazel (a natural astringent)
- Use aloe vera gel to soothe irritation
- Apply coconut oil for natural lubrication
- Use psyllium husk for softer stools
- Elevate feet with a small stool during bowel movements
- Avoid heavy lifting
- Incorporate squatting into toilet posture (using a stool)
- Kegel exercises to strengthen pelvic muscles
- Avoid spicy foods that can irritate hemorrhoids
- Avoid alcohol and caffeine
- Maintain a regular bowel movement routine
- Apply petroleum jelly for skin protection
- Chamomile tea sitz baths
- Reduce salt intake to avoid swelling
