What Are Hemroids?
Often described as "varicose veins of the Excretory Orifice and rectum", hemroids are enlarged, bulging blood vessels in and about the Excretory Orifice and lower rectum. There are two types of hemroids: external and internal, which refer to their location.
External (outside) hemroids develop near the Excretory Orifice and are covered by very sensitive skin. If a blood clot develops in one of them, a painful swelling may occur. The external hemroids feels like a hard, sensitive lump. It bleeds only if it ruptures.
Internal (inside) hemroids develop within the Excretory Orifice beneath the lining. Painless bleeding and protrusion during bowel movements are the most common symptom. However, an internal hemroids can cause severe pain if it is completely "prolapsed" - protrudes from the Excretory Orifice opening and cannot be pushed back inside.
Hemroids are one of the most common ailments known.
More than half the population will develop hemroids, usually after age 30.
Millions of Americans currently suffer from hemroids.
The average person suffers in silence for a long period before seeking medical care.
Today's treatment methods make some types of hemroids removal much less painful.
What Causes Hemroids?
An exact cause is unknown; however, the upright posture of humans alone forces a great deal of pressure on the rectal veins, which sometimes causes them to bulge. Other contributing factors include:
Spending long periods of time (e.g., reading) on the toilet
Whatever the cause, the tissues supporting the veins stretch. As a result, the veins dilate; their walls become thin and bleed. If the stretching and pressure continue, the weakened veins protrude.
