Rectal Bleeding
Rectal bleeding (bleeding from the back passage or anus) should prompt medical evaluation to determine its underlying cause. There are several potential causes of rectal bleeding, ranging from benign to more serious conditions.

Importantly, these symptoms can mask or mimic many serious bowel conditions. It is essential to have any new symptoms properly assessed.
Causes of Rectal Bleeding
Swollen blood vessels in the rectum or anus can lead to bleeding during bowel movements. Haemorrhoids are a common cause of rectal bleeding, particularly in individuals who strain during bowel movements or have chronic constipation or diarrhoea.
Small tears in the lining of the anal canal, often caused by passing hard or watery stools that can result in rectal bleeding. Anal fissures are typically accompanied by pain ‘during and after’ bowel movements.
Conditions such as Crohn’s disease and ulcerative colitis can cause inflammation and ulcers in the digestive tract, leading to rectal bleeding, diarrhoea, abdominal pain, and other symptoms.
Diverticula, small pouches that form in the colon wall, can become inflamed or infected, resulting in rectal bleeding and abdominal pain.
Rectal bleeding can be a symptom of colorectal cancer, particularly in older adults or those with a family history of the disease. Other symptoms may include changes in bowel habits, abdominal pain, and unintentional weight loss.
