K64.0: First degree haemorrhoids

You have abnormally enlarged blood vessels in your last intestinal segment.

If the blood in the blood vessels of the last intestinal segment cannot flow properly, these blood vessels may become enlarged. That can occur for instance with inflammations in the intestines or with constipation. The likelihood of enlarged blood vessels is increased by being overweight, a low-fiber diet and frequent sitting, for example. The enlarged blood vessels may cause pain, bleeding or a discharge. You may also have blood in your feces. Your anus may also be itchy. But you may also have no symptoms.

The intestines are like a tube. There is a hollow space on the inside. The intestinal wall lies around this hollow space. In your case, the enlarged blood vessels have turned inward into the hollow space of the intestines. The enlarged blood vessels are not visible from the outside.
