K62.5: Haemorrhage of anus and rectum

Haemorrhage of the anus and rectum, also referred to as rectal bleeding, is a condition in which one experiences loss of blood from the anus or rectum. This medical condition can originate from various sources within the lower digestive tract such as the colon, rectum, or anus. The blood may appear bright red or dark and mixed with stool. Additionally, rectal bleeding can manifest in different forms, varying from mild traces of blood on the toilet paper to heavy blood loss leading to anemia. Common potential causes include hemorrhoids, anal fissures, polyps, diverticulosis, and less commonly, colorectal cancer. The presentation of rectal bleeding can vary greatly among individuals, depending on the underlying cause or severity of the condition, making it important for a healthcare provider to properly diagnose the specific source of the bleeding.
