Undigested food and blood in stool2/21/2024 There are other rare causes of inflammation of the colon (colitis) or inflammation of the rectum (proctitis) that can cause rectal bleeding. The blood comes from ulcers that develop on the lining of the inflamed gut. A common symptom when the disease flares up is diarrhoea mixed with blood. Ulcerative colitis (UC) is a disease where inflammation develops in the colon and rectum. Ulcerative colitis and other forms of colitis See the separate leaflet called Crohn's Disease for details. Common symptoms include bloody diarrhoea, tummy (abdominal) pain and feeling unwell. Symptoms vary, depending on the part of the gut affected and how bad the condition is. Crohn's diseaseĬrohn's disease is a condition which causes the gut to become inflamed. See the separate leaflet called Diverticula (Diverticulosis, Diverticular Disease, Diverticulitis) for details. Diverticula can cause other symptoms such as tummy pains and changes in your normal bowel habit. The bleeding is due to a burst blood vessel that can happen in the wall of a diverticulum and so the amount of blood loss can be heavy. The bleeding is usually abrupt and painless. Several diverticula may develop over time.Ī diverticulum may occasionally bleed and you may pass some blood via your anus. They can develop on any part of the gut but usually occur in the colon. Diverticula is the word used for more than one diverticulum. DiverticulaĪ diverticulum is a small pouch in the wall of the gut (intestines). See the separate leaflet called Anal Fissure for details. The blood is usually bright red and stains the toilet paper but soon stops. You may notice blood after you pass stools (faeces). Often an anal fissure will bleed a little. Although the tear of an anal fissure is usually small (usually less than a centimetre), it can be very painful because the anus is very sensitive. Anal fissureĪn anal fissure is a small tear of the skin of the anus. See the separate leaflet called Piles (Haemorrhoids) for details. Larger haemorrhoids may cause a mucous discharge, some pain, irritation and itch. The most common symptom is bleeding after going to the toilet. Haemorrhoids are very common and many people develop one or more haemorrhoids at some stage. External haemorrhoids develop under the skin around the anus, and internal haemorrhoids form inside the rectum (the back passage). These swollen (engorged) veins and the overlying tissue may then form into one or more small swellings called haemorrhoids. ![]() These veins sometimes become wider and filled with more blood than usual. There is a network of small blood vessels (veins) within the inside lining of the anus and lower rectum. Piles (haemorrhoids) are swellings that can occur in the anus and lower back passage (lower rectum). Below is a brief overview of the more common causes: Piles Studies suggest that about 15% of all people have experienced rectal bleeding in the last year. The rectum stores stools (faeces) before they are passed out from the anus. The colon leads into the back passage (rectum) which is about 15 cm long. Some water and salts are absorbed into the body from the colon. ![]() This is split into four sections: the ascending (on the right side of your tummy), transverse (across the top of your tummy), descending (on the left side of your tummy) and sigmoid colon (in your pelvis). The main part of the large intestine is called the colon, which is about 150 cm long. Undigested food, water and waste products are then passed into the large intestine (sometimes called the large bowel). The small intestine (sometimes called the small bowel) is several metres long and is where food is digested and absorbed. The stomach starts to break up the food and then passes it into the small intestine. When we eat or drink, the food and liquid travel down the gullet (oesophagus) into the stomach. The gut (gastrointestinal tract) starts at the mouth and ends at the anus.
