Rectal bleeding can be a concerning symptom, but it’s important to understand that it can result from a variety of causes, some of which are more serious than others. Recognizing the potential causes and knowing when to seek medical attention is crucial for proper diagnosis and treatment. This can also help give you ease of mind when dealing with rectal bleeding and help you understand why it might be happening.
Understanding Rectal Bleeding
Rectal bleeding refers to any blood passed from the anus, often seen on toilet paper, in the toilet bowl, or mixed with stool. The color of the blood can vary from bright red to dark maroon, depending on the location of the bleeding within the gastrointestinal (GI) tract. There are various causes for rectal bleeding, and it’s important to tell what your symptoms are and what they may be related to.
Hemorrhoids are swollen blood vessels in the rectum or anus that can cause bright red bleeding during bowel movements. They are often associated with straining, constipation, or prolonged sitting. While hemorrhoids are generally not serious, they can be uncomfortable and may require treatment to alleviate symptoms.
Anal fissures are small tears in the lining of the anus, often caused by passing hard or large stools. They can lead to pain and bleeding, especially during bowel movements. Like hemorrhoids, fissures typically cause bright red blood.
Conditions like Crohn’s disease and ulcerative colitis are types of irritable bowel disease (IBD) that cause chronic inflammation in the GI tract. These conditions can lead to rectal bleeding, often accompanied by diarrhea, abdominal pain, and weight loss.
Polyps are growths on the colon's inner lining, and while most are benign, some can develop into cancer. Rectal bleeding can be an early sign of colon cancer, particularly if the bleeding is dark and mixed with stool. Early detection through screening is vital for treatment and prognosis.
