Internal hemorrhoids are the most common form of hemorrhoids. Interestingly, every form of hemorrhoids is generally the same except for where it is located. The different forms include internal hemorrhoids, external and thrombosed.
Internal hemorrhoids are located on the inside of your anus, usually about an inch or so inside the rectum. Generally speaking, the main indication that you have an internal hemorrhoid is the appearance of blood that shows on the stool, toilet paper or inside of the toilet. As you probably know, any type of a hemorrhoid is an inflamed, swollen vein as the result of excess pressure in that region.
Internal hemorrhoids are, as mentioned before, the most common type of hemorrhoid. Generally, they are painless. They can, as mentioned before, cause bleeding however. You should treat your internal hemorrhoids as soon as you are aware of them.
The reason for this is because if internal hemorrhoids are not treated within a reasonable amount of time, they can cause your veins to stretch and prolapse (fall down) outside of your body. You can imagine how undesirable that situation would be. That could in fact result in needing to push the vein back in after you have a bowel movement. Not fun.
It is important to note the different stages of internal hemorrhoids. The extent of descent into the anal canal or even the outside of the anus is what determines each stage. The first stage is where your internal hemorrhoid is inflamed, but not prolapsed. It will produce light bleeding, if at all. This leads us to the second stage.
The second stage of an internal hemorrhoid is when it does in fact prolapse when having a bowel movement. It will, however, eventually return to its original position at some point, though. The third stage of internal hemorrhoids is when the enlarged vein will actually come out during each bowel movement and will actually then need to be put back in. The fourth and final stage of internal hemorrhoids is when the hemorrhoidal vein is permanently prolapsed. It cannot be put back in, because it will always fall back out.
