Hemorrhoids, commonly known as piles refer to a condition in which the veins around the anus or in the rectum become swollen and inflamed. Majority of people may suffer from hemorrhoids at some point in their life time. It is more common in individuals aged between 45 and 65 years and in pregnant women. External hemorrhoids occur on the skin around the anus whereas internal hemorrhoids develop in the rectum. Internal hemorrhoids tend to protrude out through the anus.

Several factors are considered to as the causes for hemorrhoids and some of them include

  • Chronic constipation and diarrhea
  • Excessive straining during bowel movement
  • Diet which lacks fibrous food
  • Aging (weak connective tissue in the rectum and anus)
  • Pregnancy (increased pressure in the abdomen)


Internal hemorrhoids: The most common symptom is passage of bright red blood with the stools. If the hemorrhoids have prolapsed, it causes pain, discomfort and itching around the anus.

External hemorrhoids: Blood clots may form in the swollen veins causing bleeding, painful swelling or a hard lump.


Your doctor will perform physical examination which involves digital rectal exam with a gloved, lubricated finger and an anoscope. Additional diagnostic tests may be ordered to rule out other causes of bleeding.

  • Colonoscopy: Colonoscopy is a procedure in which a flexible lighted tube is passed through the anus into the rectum and the colon. The colonoscope helps to view the pictures of inside of the rectum and colon.
  • Sigmoidoscopy: This procedure uses a shorter tube called a sigmoidoscope to transmit images of the rectum and the sigmoid colon (the lower portion of the colon).
  • Barium enema X-ray: This procedure involves taking an X-ray after injecting a contrast material called barium into the colon.


Lifestyle modifications and dietary changes often are helpful in reducing the symptoms of hemorrhoids. A diet having high fiber content soften the stools and helps to pass them easily thereby avoids straining. Fruits, vegetables and cereals serve as a good source of dietary fibers. Fiber supplements such as methylcellulose or stool softeners can be taken. Drinking plenty of water (8-ounce glasses) and adequate exercise helps prevent constipation. Over-the-counter creams and suppositories help relieve the pain and itching. However, these are short time remedies as long-term use can cause damage to the skin.

Medical Treatment

Outpatient treatments are provided for internal hemorrhoids and include the following:

Rubber band ligation: In this technique, an elastic band is tied around the base of the hemorrhoid to cut off blood supply. The procedure is performed on an outpatient basis under topical anesthesia. Your doctor inserts an anoscope, a viewing instrument, into your anus and passes a small tool called a ligator through it. The hemorrhoid is grasped with forceps and the ligator is passed over the hemorrhoid to place a rubber band. Without blood supply, the tissue dies and sloughs off in 1 or 2 weeks.

As with any procedure, rubber band ligation may involve certain risks and complications which include severe pain, anal bleeding, infection in the anal canal and trouble urinating.

Sclerotherapy: This involves injecting a chemical directly into the hemorrhoid tissue. The solution numbs the site and hardens the hemorrhoid tissue leading to scar formation. After four to six weeks, the hemorrhoid shrinks and falls off. The disadvantage of this method is the recurrence of hemorrhoids after about a year.

Infrared photocoagulation: Infrared photocoagulation, indicated for small-to-medium internal hemorrhoids, uses infrared rays to form scar tissue from the intense heat created and cuts off the blood supply to the hemorrhoid causing death of the tissue which then falls off. Laser or electric current can be used instead of the infrared beams. Infrared photocoagulation is associated with intense pain immediately after the procedure, which can be managed with pain medication. There is a chance of recurrence of hemorrhoids.

Surgical removal becomes necessary when the hemorrhoids are large enough and do not respond to conservative treatment.
