What Are Hemorrhoids?
The term hemorrhoids refers to a condition in which the veins around the anus or lower rectum are swollen and inflamed. Hemorrhoids may result from straining to move stool. Other contributing factors include pregnancy, aging, chronic constipation or diarrhea, and anal intercourse. Hemorrhoids are both inside and above the anus (internal) or under the skin around the anus (external). Hemorrhoids (piles) arise from congestion of internal and/or external venous plexuses around the anal canal.

Hemorrhoids are classified into four degrees, depending on severity, so that they can more easily be evaluated for possible surgery. For more detailed information, view our page Surgical Classification of Hemorrhoids.
What Are the Symptoms of Hemorrhoids?
Many anorectal problems, including fissures, fistulae, abscesses, or irritation and itching (pruritus ani), have similar symptoms and are incorrectly referred to as hemorrhoids. Hemorrhoids usually are not dangerous or life threatening. Rarely, a patient can have bleeding so severe, that severe anemia or death may occur. In some cases, hemorrhoidal symptoms simply go away within a few days. But in most cases, hemorrhoidal symptoms eventually return, often worse than they were before. Although many people have hemorrhoids, not all experience symptoms. The most common symptom of internal hemorrhoids is bright red blood covering the stool, on toilet paper, or in the toilet bowl. However, an internal hemorrhoid may protrude through the anus outside the body, becoming irritated and painful. This is known as a protruding hemorrhoid. Symptoms of external hemorrhoids may include painful swelling or a hard lump around the anus that results when a blood clot forms. This condition is known as a thrombosed external hemorrhoid. In addition, excessive straining, rubbing, or cleaning around the anus may cause irritation with bleeding and/or itching, which may produce a vicious cycle of symptoms. Draining mucus may also cause itching.
How Common Are Hemorrhoids?
Hemorrhoids are very common in both men and women. About half of the population have hemorrhoids by age 50. Hemorrhoids are also common among pregnant women. The pressure of the fetus in the abdomen, as well as hormonal changes, cause the hemorrhoidal vessels to enlarge. These vessels are also placed under severe pressure during childbirth. For most women, however, hemorrhoids caused by pregnancy are a temporary problem.
How Are Hemorrhoids Diagnosed?
A thorough evaluation and proper diagnosis by the doctor is important any time bleeding from the rectum or blood in the stool occurs. Bleeding may also be a symptom of other digestive diseases, including colorectal cancer. The doctor will examine the anus and rectum to look for swollen blood vessels that indicate hemorrhoids and will also perform a digital rectal exam with a gloved, lubricated finger to feel for abnormalities. Closer evaluation of the rectum for hemorrhoids requires an exam with an anoscope, a hollow, lighted tube useful for viewing internal hemorrhoids, or a proctoscope, useful for more completely examining the entire rectum. To rule out other causes of gastrointestinal bleeding, the doctor may examine the rectum and lower colon (sigmoid) with sigmoidoscopy or the entire colon with colonoscopy. Sigmoidoscopy and colonoscopy are diagnostic procedures that also involve the use of lighted, flexible tubes inserted through the rectum.
What Is the Treatment?
Medical treatment of hemorrhoids is aimed initially at relieving symptoms. Measures to reduce symptoms include · Warm tub baths several times a day in plain, warm water for about 10 minutes. · Application of a hemorrhoidal cream or suppository to the affected area for a limited time. Preventing of the recurrence of hemorrhoids will require relieving the pressure and straining of constipation. Doctors will often recommend increasing fiber and fluids in the diet. Eating the right amount of fiber and drinking six to eight glasses of fluid (not alcohol) result in softer, bulkier stools. A softer stool makes emptying the bowels easier and lessens the pressure on hemorrhoids caused by straining. Eliminating straining also helps prevent the hemorrhoids from protruding. Good sources of fiber are fruits, vegetables, and whole grains. In addition, doctors may suggest a bulk stool softener or a fiber supplement such as psyllium or methylcellulose. In some cases, hemorrhoids must be treated endoscopically or surgically. These methods are used to shrink and destroy the hemorrhoidal tissue. The doctor will perform the procedure during an office or hospital visit. A number of methods may be used to remove or reduce the size of hemorrhoids. Painless non-surgical techniques, lasers for hemorrhoids, harmonic scalpel for hemorrhoids, and the use of hemorrhoid medications are discussed further in this web site.
How Are Hemorrhoids Prevented?
The best way to prevent hemorrhoids is to keep stools soft so they pass easily, thus decreasing pressure, and to empty bowels without undue straining as soon as possible after the urge occurs. Exercise, including walking, and eating a high fiber diet, help reduce constipation and straining by producing stools that are softer and easier to pass.
Painless Techniques for the Treatment of Hemorrhoids
Major surgery for hemorrhoids can generally be avoided in favor of more sophisticated and often painless methods of treatment. Non-surgical methods of treatment are available to most patients as a viable alternative to a permanent hemorrhoid cure.
Bipolar electrotherapy is applied for a directed coagulation effect of the mucous membrane near the hemorrhoid. Specialized Bipolar Circumactive Probes (BICAP) are effective for the treatment of bleeding internal hemorrhoids. Bipolar electrotherapy is applied for a directed coagulation effect of the mucous membrane near the hemorrhoid. Specialized probe designs are effective for the treatment of bleeding internal hemorrhoids.

Hemorrhoidal Arterial Ligation (H.A.L.) is performed using a modified proctoscope in conjunction with a Doppler ultrasound flowmeter. A needle and thread is passed beneath the artery, and a knot is externally tied, to stop the blood flow to the hemorrhoid. For more informaion on the HAL-RAR Method visit www.hemorrhoid.net.
Therapeutic galvanic waves applied directly to the hemorrhoid, produces a chemical reaction that shrinks and dissolves hemorrhoidal tissue. This technique is most effective when it is used on internal hemorrhoids.

To shrink the hemorrhoid and its blood vessels, medicine is injected into the mucous membrane near the hemorrhoid. This method is reserved for the smallest of hemorrhoids.
A device called a photocoagulator focuses infrared light into a fine point at the end of a probe, which spotwelds the hemorrhoid in place. This is used for hemorrhoids that are actively bleeding.
A special instrument fits a small rubber band over part of the hemorrhoid. A tight rubber band stops the blood flow into the pinched-off portion, which falls off in about a week. This technique is widely used for hemorrhoids protruding into the anal canal.
