Hemorrhoids are part of the normal anatomy of the anus and lower rectum. They act as cushions to protect the anal skin from the passage of stool. Hemorrhoids usually are not a problem, but they can become a problem if they swell, bleed or protrude — come out of the rectum to the outside of the anus.
Hemorrhoids are either inside the anus, called internal, or under the skin around the anus, called external. Hemorrhoids that come from the inside are covered with the lining of the rectum, called mucosa, and those that are on the outside are covered with skin. Sometimes the internal hemorrhoids are connected to external hemorrhoids.
Although many people have hemorrhoids, not all experience symptoms. Internal hemorrhoids may cause bright red blood in the toilet bowl, a feeling of fullness or discomfort, or mucus discharge. They also can protrude, or pop out, with a bowel movement; usually, they return to the inside by themselves.
External hemorrhoids are felt as a lump near the anus that can cause pain. The lump is caused by a blood clot, causing a purple-blue color.
Because bleeding can be a symptom of cancer in the colon or rectum, a colonoscopy may need to be done before we will treat your hemorrhoids. This is a diagnostic procedure that uses a lighted, flexible tube inserted through the rectum. If you have a family history of cancer, are over age 50 or have other symptoms or risk factors, this test can catch colorectal cancer when it is small. This procedure is done as an outpatient basis. Small numbers of people who have had this operation may leak gas or stool.
There are several ways to treat hemorrhoids. The best way may be to relieve the symptoms and prevent the hemorrhoids from becoming problematic. This is best done by:
If your hemorrhoids do not respond to the above therapies, or are already very problematic, there are a number of other treatments options, including:
Rubber Band Ligation
Also called banding, this involves placing a very small rubber band around the base of the hemorrhoid inside the rectum. The band cuts off circulation and the hemorrhoid withers away within seven to 10 days. This leaves a scar that prevents further bleeding and prolapse. This is usually done in the office but sometimes it is done in surgery.
What to expect from banding:
A chemical solution is injected around the blood vessel to shrink the hemorrhoid. This causes inflammation and scarring. This is done in the office but has a higher chance of only working temporarily. You may return to daily activities right away.
When hemorrhoids are severe, extensive, prolapsing or incarcerated, they may require removal by surgery known as hemorrhoidectomy. This is done under anesthesia. Because there is a risk of causing permanent damage to the sphincter — the muscle that controls your bowel movements — this operation is only done if absolutely necessary.
What to expect from hemorrhoidectomy:
When an external hemorrhoid develops, it can be treated with excision, or cutting open, of the hemorrhoid or clot if you are able to be seen within the first 24 hours of pain. After that, the hemorrhoid will begin to go away on its own and cutting it open will not help it heal more quickly. Warm baths are very helpful for this.
You may have noticed that there is no mention of creams or suppositories in this handout. We believe that these may help but they also can cause problems. The anal area prefers to be dry and because it is a very sensitive area, it can develop allergies to some preparations.
A high-fiber diet will help you have soft, regular bowel movements. Also, the best time to have a bowel movement is when your body gives you an urge to go — this will minimize problems with hemorrhoids, fissures, itching and other common colon, rectal and anal problems.
A diet high in fiber has about 25 to 30 grams of fiber per day. For information on how to increase your fiber through diet, please see Increasing Fiber Intake. For information on using supplements, please see Fiber Supplements.
