Hemorrhoids or piles refer to a condition wherein the
veins around the anus or lower rectum get swollen and inflamed. In simple words
hemorrhoids are veins that get swollen in the anal canal. The term hemorrhoids
refer to 'cushions of tissue filled with blood vessels at the intersection of
the rectum and the anus'. Hemorrhoids are painful but surely not dangerous or
Hemorrhoids are common in both
men and women. Almost half the population suffers from hemorrhoids when they reach
50. About 89% of Americans suffer from hemorrhoids. Hemorrhoids are very common
among pregnant women. The pressure of the fetus on the abdomen and hormonal
changes affect the blood vessels and force them to enlarge. These vessels
experience severe pressure during childbirth thereby making hemorrhoid a common
occurrence in women. In general hemorrhoids induced by pregnancy are a
temporary problem in most women.
What causes hemorrhoids?
Too much pressure exerted on the
veins in the pelvic and rectal area can cause hemorrhoids. Hemorrhoids can
occur either inside the anus (internal) or under the skin around the anus (external).
The following conditions can cause strain on the veins thus causing hemorrhoids:
- Straining too much to pass stools
- Sitting for too long
- Chronic constipation
- Cigarette smoking
- Excessive coughing
- Having anal intercourse
- Lifting heavy weight
Types of hemorrhoids
Internal hemorrhoids: Veins that get swollen inside the anal canal
are referred to as internal hemorrhoids. Internal hemorrhoids are not very
painful as there are no pain receptors in this area. Most people who have
internal hemorrhoids are not even aware of having them. Internal hemorrhoids
can bleed when they are irritated.
External hemorrhoids: Veins that get swollen near the opening of
the anus are termed as external hemorrhoids. These hemorrhoids are at times
painful and cause swelling and irritation.
Anal fissure: A thin tear in the anal area is an anal fissure. This
hemorrhoid is itchy, painful and bleeds while passing stools.
Prolapsed hemorrhoids: These hemorrhoids are a type of internal hemorrhoid
and they stretch down until they protrude outside the anus. This type of
hemorrhoid can be painful.
Thrombosed hemorrhoids: A blood clot forms inside the external
hemorrhoid thus causing thrombosed hemorrhoid. This type of hemorrhoid is very
painful and can be felt as a stiff but tender mass in the anal area.
Symptoms of hemorrhoids
Although many people have hemorrhoids,
not all experience symptoms. Symptoms vary based on whether the hemorrhoid is
internal or external. Common symptoms for all types of hemorrhoids include:
- Bleeding during bowel movements
- Rectal pain
Diagnosis of hemorrhoids
People experiencing bleeding from
the rectum or blood in the stool should get a thorough examination done through
the doctor. Correct diagnosis of hemorrhoids is very important as bleeding
could also be a symptom of other digestive diseases or colorectal cancer. Diagnosis
for hemorrhoids includes:
- Physical examination of the anus and the rectum by the doctor to check for swollen blood vessels that can be a vital sign of hemorrhoids
- A digital rectal exam to check for abnormalities, if any
- An anoscope (a hollow, lighted tube is used for viewing internal hemorrhoids) helps to view the rectum closely for hemorrhoids
- Doctors may also use a proctoscope for a complete examination of the rectum
- A sigmoidoscopy (use of lighted, flexible tubes inserted through the rectum) is used to view the rectum and lower
colon/sigmoid, this helps in ruling out possibilities of other causes of gastrointestinal
Treatment for hemorrhoids
- Tub/sitz baths several times a day in plain/warm
water for about 10 minutes
- Increase intake of fiber and fluids to prevent
- Ice packs can help reduce swelling.
- Applying hemorrhoidal cream to the affected area as
suggested by the doctor.
- In few cases when the hemorrhoid is severe, it is
removed surgically. Surgery shrinks and destroys the hemorrhoidal tissue.
Common techniques followed in removal of hemorrhoids
Hemorrhoidectomy: At times severe internal or external hemorrhoids
may require removal by surgery; this procedure is known as hemorrhoidectomy.
Sclerotherapy: A chemical solution is injected around the blood
vessel so as to shrink the hemorrhoid.
Rubber band ligation: A rubber band is positioned inside the rectum
around the bottom of the hemorrhoid. The band helps in cutting off blood circulation
thereby forcing the hemorrhoid to wither away after a few days.
A special device is used to burn hemorrhoidal tissue.
Laser coagulation: This is a new technique; electric current is
applied to remove the hemorrhoids.

Pregnancy and hemorrhoids
Pregnancy makes women more prone to hemorrhoids. The main reason behind hemorrhoids in pregnant women is
- The growing uterus applies pressure on the veins thus causing the veins in the lower limbs to swell.
- Constipation is common during pregnancy which can also cause or worsen hemorrhoids.
- An increased level of the hormone progesterone during pregnancy allows the walls of the veins to relax thus causing swelling of the same. Progesterone also causes constipation thus causing hemorrhoids.
