Blood in stools, also known as rectal bleeding, can be a concerning symptom. The condition occurs when there is bleeding in the digestive tract, resulting in blood appearing in the stool.

While it might be alarming, there can be several reasons behind the presence of blood in stools. In this article, we will explore 11 visual explanations for blood in stools, which can help you understand the potential causes and when to seek medical advice.

1. Hemorrhoids

Hemorrhoids are one of the most common causes of blood in stools. These are swollen blood vessels that occur in the rectum or anus, leading to rectal bleeding.

Blood from hemorrhoids typically appears bright red and is often noticed after bowel movements.

2. Anal Fissures

An anal fissure is a tear in the lining of the anus, which can result in blood in stools. This condition is often caused by passing hard, dry stools or straining during bowel movements.

Blood from anal fissures is usually bright red and can be seen on the surface of the stool or on toilet paper.

3. Gastrointestinal Infections

Gastrointestinal infections, such as bacterial or viral gastroenteritis, can cause blood in stools. These infections inflame the intestines and can lead to bleeding.

Blood in stools due to gastrointestinal infections may be accompanied by other symptoms like diarrhea, abdominal pain, and fever.

4. Inflammatory Bowel Disease (IBD)

Inflammatory bowel disease, including conditions such as Crohn’s disease and ulcerative colitis, can cause blood in stools. These chronic conditions cause inflammation in the gastrointestinal tract, leading to ulcers or sores that bleed.

Blood in stools from IBD is often accompanied by diarrhea, abdominal pain, and weight loss.

5. Colon Polyps

Colon polyps are growths that occur on the inner lining of the colon. While most polyps are harmless, some can turn cancerous over time. Blood in stools can be a sign of bleeding from these polyps.

It is important to detect and remove polyps promptly to prevent the development of colon cancer.

6. Colorectal Cancer

Colorectal cancer can cause blood in stools. This type of cancer typically starts as small polyps that become cancerous over time. Blood in stools can be a warning sign of colorectal cancer.

It is crucial to get regular screenings for early detection and treatment.

7. Diverticular Disease

Diverticular disease occurs when small pouches called diverticula develop in the walls of the colon. Inflammation or infection of these diverticula can lead to rectal bleeding.

Diverticular disease is more common in older adults and can cause pain, changes in bowel habits, and blood in stools.

8. Angiodysplasia

Angiodysplasia refers to abnormal, fragile blood vessels in the gastrointestinal tract. These blood vessels can rupture easily, leading to bleeding in the digestive system.

Angiodysplasia is commonly seen in older individuals and might cause blood in stools.

9. Peptic Ulcers

Peptic ulcers are open sores that develop on the lining of the stomach or the upper portion of the small intestine. These ulcers can cause bleeding, resulting in blood appearing in stools.

Peptic ulcers can be caused by an infection with Helicobacter pylori bacteria, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), or excessive alcohol consumption.

10. Anal Cancer

While rare, anal cancer can cause blood in stools. Anal cancer can develop in the tissues of the anus and can lead to rectal bleeding.

It is essential to consult a healthcare professional if you experience persistent blood in stools or other concerning symptoms.

11. Medications and Medical Procedures

Certain medications, such as blood thinners or anti-inflammatory drugs, can increase the risk of bleeding in the gastrointestinal tract.

Additionally, some medical procedures, like colonoscopy or biopsy, can cause temporary blood in stools due to minor tissue trauma.

When to Seek Medical Advice

While blood in stools can sometimes be harmless and temporary, it can also indicate a serious underlying condition. It is crucial to seek medical advice if you experience any of the following:.

Persistent rectal bleeding
Blood in stools accompanied by severe abdominal pain
Changes in bowel habits along with blood in stools
Unexplained weight loss
Fatigue or weakness
Family history of colorectal cancer or other gastrointestinal conditions

If you notice any of these symptoms, it is essential to consult a healthcare professional for a proper evaluation and diagnosis.

Conclusion

While blood in stools can be alarming, understanding the visual explanations for this symptom can help you identify potential causes. Remember that only a healthcare professional can provide an accurate diagnosis.

It is always better to seek medical advice if you have concerns about blood in stools or any other unusual symptoms.
