Frequently, the only sign that internal hemorrhoids exist is bright red blood that appears on the surface of the stool, in the toilet bowl, or on the toilet paper. But, if the pressure and swelling continue, the hemorrhoidal veins may stretch out of shape, sometimes so much that they bulge through the anus to the outside of the body. The veins around the anus can also become swollen, causing external hemorrhoids. These swollen veins bleed easily, either from straining or rubbing, and irritation from draining mucus may cause itching in the anal area. If blood clots form in these hemorrhoids, the pain can be severe.
Hemorrhoids are the most common source of bleeding from the rectum and the anus.
However, if the bleeding lasts for more than a couple of days, it's important to see a doctor for an exam. Treatment for hemorrhoids depends not only on the severity of the symptoms, but also on the patient's reaction to those symptoms. Sometimes, doing nothing is the best treatment of choice. For others, surgery may be an option. The first step in treating hemorrhoids is to relieve the pressure and straining.
