Hemorrhoids, also known commonly as piles, are the dilation of a vein in the rectum or anus. This is a very common and painful condition that is usually caused by constipation, genetic predisposition, being too long standing, or associated with pregnancy. There are two variations of this pathology:external and internal hemorrhoids. The first generate protrusions on the ring on the outside of the anus, so they are easier to diagnose and cause pain when sitting, as well as traces of blood in stool. Treatment consists in applying creams and warm water in the affected area and in cases of severe pain, taking painkillers. On the other hand, internal hemorrhoids occur inside the anus, causing bleeding in the stool and itching in the anal region. If they grow, a surgical intervention may be necessary to remove.
