Did You Know?
Wireless capsule endoscopy is a remarkable new technique that can help diagnose problems not detected by conventional studies such as gastroscopy and colonoscopy. During this test, the patient swallows a tiny video capsule, about the size of a large vitamin, that can transmit up to 50,000 color images as it moves through the digestive tract. Ask us about this procedure on your next visit.

Hemorrhoids
are swollen veins. Each of us has veins around the anus that tend to stretch under pressure, somewhat like varicose veins in the legs. When these veins swell, we call them "hemorrhoids." One set of veins is inside the rectum (internal), and another is under the skin around the anus (external).
also are known as "piles." As a rule, they do not cause pain or bleeding. Problems can occur, however, when these veins become swollen because pressure is raised in them. Increased pressure may result from straining to move your bowels, from sitting too long on the toilet, or from other factors such as pregnancy, obesity, or liver disease.
The only sign you may notice from internal hemorrhoids is bright red blood on the toilet paper or in the toilet bowl. Sometimes, however, these veins stretch, and may even fall down (prolapse) through the anus to outside the body (protruding hemorrhoids). When this happens, the vein may become irritated and painful.
The set of veins around the anus causes problems when blood clots form in them, and they become large and painful. (These are called thrombosed external hemorrhoids.) You may notice a tender lump on the edge of the anus. Bleeding starts when the swollen veins are scratched or broken by straining or rubbing. People who have external hemorrhoids may feel itching at the anus too. This might result from draining mucus and irritation caused by too much rubbing or cleaning of the anus, or alternatively by inadequate anus hygiene leading to particles of stool around the anus caught in between the hemorrhoidal protrusions. Any stool particles on the perianal skin will cause itching and irritation in this area.
Often all that is needed to reduce symptoms is to include more fiber in your diet to soften the stool. Eat more fresh fruits, leafy vegetables, whole grain breads and cereals (especially bran). Drinking six to eight glasses of fluid (not alcohol) each day will also help. Softer stools make it easier to empty the bowels and lessen pressure on the veins.
Good hygiene is also important. Bathe the anus gently after each bowel movement using soft, moist toilet paper (or a commercial moist pad). Avoid a lot of wiping. If necessary, you can even use a bath or shower as an alternative to wiping. After bathing, dry the anus gently with a soft cloth or towel.
