Discovering blood in your stool can be a cause for concern and may indicate an underlying health issue.

While it is important to consult with a healthcare professional for an accurate diagnosis, understanding the common reasons for blood in stool can help you make an informed decision about seeking medical advice. In this article, we discuss eight common causes of blood in stool.

1. Hemorrhoids

Hemorrhoids, also known as piles, are a common cause of blood in stool. They are swollen blood vessels in the rectum or anus that may cause discomfort, itching, and bleeding during bowel movements.

Hemorrhoids can be internal or external, and while they are generally not harmful, they can be treated to alleviate symptoms.

2. Anal Fissures

Anal fissures are small tears in the lining of the anus, which can occur due to passing hard, dry stools. Along with pain and discomfort, anal fissures may cause bright red blood in the stool or on the toilet paper.

These fissures usually heal on their own within a few weeks, but proper hydration and dietary changes can help prevent their recurrence.

3. Gastrointestinal Infections

Gastrointestinal infections caused by viruses, bacteria, or parasites can lead to bloody stools. Common infections such as salmonella, E. coli, or giardiasis can cause inflammation in the intestines and result in bloody diarrhea.

These infections usually require medical treatment, and it is essential to stay hydrated to avoid complications.

4. Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic condition that causes inflammation in the digestive tract. Conditions such as Crohn’s disease and ulcerative colitis, which are types of IBD, can lead to blood in the stool.

Other symptoms of IBD include abdominal pain, diarrhea, weight loss, and fatigue. Treatment for IBD often involves medication, lifestyle changes, and sometimes surgery.

5. Diverticulitis

Diverticula are small, bulging pouches that can form in the lining of the lower part of the colon. When these pouches become inflamed or infected, a condition called diverticulitis occurs.

In addition to abdominal pain and fever, diverticulitis can cause blood in the stool. Treatment may involve antibiotics, a liquid diet, and in severe cases, surgery to remove the affected section of the colon.

6. Colon Polyps

Colon polyps are growths that occur on the inner lining of the large intestine. While most polyps are noncancerous, some may develop into colorectal cancer over time. Blood in the stool can be a sign that a polyp is bleeding.

Regular colonoscopies are essential for detecting and removing polyps before they become cancerous.

7. Peptic Ulcers

Peptic ulcers are sores that can develop in the stomach lining (gastric ulcers) or the upper part of the small intestine (duodenal ulcers). These ulcers can cause bleeding, leading to the presence of blood in the stool.

Other symptoms may include abdominal pain, indigestion, bloating, and unintentional weight loss. Treatment for peptic ulcers typically involves medication to reduce stomach acid and antibiotics to eliminate H. pylori bacteria.

8. Colorectal Cancer

While less common, blood in the stool can be a symptom of colorectal cancer. As the cancerous tumor grows, it can cause bleeding and result in dark or bright red blood in the stool.

Other symptoms may include persistent abdominal discomfort, changes in bowel habits, unintended weight loss, and fatigue. Early detection and treatment are crucial for improving the prognosis of colorectal cancer.

It is important to note that the presence of blood in your stool should not be ignored, and a healthcare professional should evaluate your symptoms. They will be able to diagnose the underlying cause and recommend an appropriate treatment plan.
