Hemorrhoids-Topic Overview
Hemorrhoids Guide
Hemorrhoids are swollen veins in the anal canal. This common problem can be painful, but it's usually not serious.
Veins can swell inside the anal canal to form internal hemorrhoids. Or they can swell near the opening of the anus to form external hemorrhoids. You can have both types at the same time. The symptoms and treatment depend on which type you have.
Many people have hemorrhoids at some time.
Too much pressure on the veins in the pelvic and rectal area causes hemorrhoids.
Normally, tissue inside the anus fills with blood to help control bowel movements. If you strain or sit on the toilet a long time to move stool, the increased pressure causes the veins in this tissue to swell and stretch. This can cause hemorrhoids.
Diarrhea or constipation also may lead to straining and can increase pressure on veins in the anal canal.
Pregnant women can get hemorrhoids during the last 6 months of pregnancy. This is because of increased pressure on the blood vessels in the pelvic area. Straining to push the baby out during labor can make hemorrhoids worse.
Being overweight can also lead to hemorrhoids.
The most common symptoms of both internal and external hemorrhoids include:
With internal hemorrhoids, you may see bright red streaks of blood on toilet paper or bright red blood in the toilet bowl after you have a normal bowel movement. You may see blood on the surface of the stool.
Internal hemorrhoids often are small, swollen veins in the wall of the anal canal. But they can be large, sagging veins that bulge out of the anus all the time. They can be painful if they bulge out and are squeezed by the anal muscles. They may be very painful if the blood supply to the hemorrhoid is cut off. If hemorrhoids bulge out, you also may see mucus on the toilet paper or stool.
