The Difference Between Internal Hemorrhoids and External Hemorrhoids
There are two primary types of bleeding hemorrhoids: internal and external. See below for the more detailed description of The Difference Between Internal Hemorrhoids and External Hemorrhoids.
You can't see or feel these hemorrhoids, usually don't hurt or itch. But straining or irritation from passing stool can injure hemorrhoid's delicate surface and cause it to bleed.
You may notice small amounts of hemorrhoids bleeding on your toilet tissue or in the toilet bowl. Because internal membranes lack pain-sensitive nerve fibers, these hemorrhoids usually don't cause discomfort.
However, you may experience a feeling of fullness in your rectum following a bowel movement.
Sometimes, internal hemorrhoid may stretch down until it bulges outside your anus. It is called a prolapsed hemorrhoid. A prolapsed hemorrhoid will come back inside your rectum on its own, or you could gently push it back inside. If hemorrhoid remains displaced (prolapsed), it can cause a constant, dull ache. When irritated, it can itch or bleed.
Internal hemorrhoids are pretty harmless. But since their bleeding could mask blood from a dangerous source of colorectal cancer, they should be treated.
External hemorrhoids include the veins outside the anus. They usually cause most of the symptoms we commonly hear about --- pain, burning, and itching. Small external hemorrhoids typically do not produce symptoms.
Larger ones, however, can interfere and painful with cleaning the anal area after a bowel movement. If a blood clot forms, you may feel a tender lump on the edge of your anus. You may see some bleeding from your hemorrhoids on the toilet paper or in the toilet after a bowel movement.
If external hemorrhoid becomes strangulated (cut off from blood supply), a clot can form in it and become an excruciatingly painful thrombosed hemorrhoid. Because of these unpleasant symptoms, external hemorrhoids get the most treatment attention.
Once the rectal veins have been stretched out and hemorrhoids created, they are trying to get rid of entirely and tend to recur with less straining than it took to cause them in the first place.
Fortunately, good habits and simple medical treatment usually control hemorrhoids well, and surgery is only recommended in unusually severe cases.
