Why Might I Experience a Feeling of Fullness in the Anus?

When you feel full in your anus, it might be because something is pressing on or stretching the tissues there. One common reason is enlarged hemorrhoids. These are swollen blood vessels in the anus that can cause a bulge and make you feel full or uncomfortable. Another possibility is that the rectum—the last part of your large intestine—might be enlarged or holding more content than usual. This extra filling in the rectum can send signals that feel like fullness in the anus, even when there isn’t a problem with the muscles themselves. A third cause can be an anal fissure, which is a small tear in the lining of the anus. This tear can cause pain or a feeling of pressure when the skin is stretched. Remember, if the sensation is bothersome or lasts for a long time, it is a good idea to talk with a healthcare provider to understand it better and discuss ways to feel more comfortable.
