Finding blood on the toilet paper after wiping can be alarming. Rectal bleeding, while sometimes a sign of a serious condition, is often caused by minor and treatable issues. Understanding the potential causes can help you determine when it’s necessary to seek medical advice and when it might be a temporary concern. This article explores common reasons for blood when you wipe, helping you navigate this often-sensitive health issue.
Common Causes of Blood When You Wipe
Several factors can lead to blood appearing when you wipe. It’s important to note the color of the blood, any accompanying symptoms, and the frequency of the bleeding to help pinpoint the potential cause.
1. Hemorrhoids: A Frequent Culprit
Hemorrhoids are swollen veins in the anus and rectum that are very common, especially as we age. They can be located inside the rectum (internal hemorrhoids) or under the skin around the anus (external hemorrhoids). Often described as similar to varicose veins, hemorrhoids can become irritated and bleed, particularly during or after bowel movements.

Why hemorrhoids cause bleeding when wiping: When you have a bowel movement, especially if stools are hard or you strain, hemorrhoids can be further irritated or even rupture slightly. This can result in bright red blood on the toilet paper after wiping, or even in the toilet bowl.
Factors that increase the risk of hemorrhoids include:
- Straining during bowel movements: This increases pressure on the veins in the rectum and anus.
- Chronic constipation or diarrhea: Both can irritate the rectal area.
- Pregnancy: Hormonal changes and increased pressure in the abdomen during pregnancy can contribute to hemorrhoids.
- Obesity: Excess weight can put more pressure on rectal veins.
- Prolonged sitting on the toilet: This can also increase pressure.
- Low-fiber diet: Lack of fiber can lead to constipation and harder stools.
- Age over 50: Hemorrhoids become more common with age.
Managing hemorrhoids: Many hemorrhoid symptoms can be managed at home with over-the-counter creams and suppositories, warm baths (sitz baths), increasing fiber intake, and using stool softeners. If home treatments aren’t effective, or if bleeding is persistent or severe, a doctor may recommend minor procedures or surgery.
2. Anal Fissures: Tears Causing Pain and Bleeding
Anal fissures are small tears in the lining of the anus. These tears are frequently caused by passing hard stools and can be quite painful, especially during and after bowel movements.

Why anal fissures cause bleeding when wiping: The tear exposes sensitive nerve endings and blood vessels. Wiping after a bowel movement can irritate the fissure, causing further pain and bright red bleeding, which you’ll notice on the toilet paper.
Symptoms of anal fissures:
- Sharp pain during and after bowel movements.
- Bright red blood on toilet paper or in the stool.
- Visible tear in the anal skin.
- Sometimes, a burning or itching sensation in the anus.
Treating anal fissures: Similar to hemorrhoids, initial treatment for fissures often includes warm baths, increased fiber intake, and stool softeners to make bowel movements easier. Topical creams, including prescription options, can help heal the fissure. In chronic cases, surgery might be necessary.
3. Diverticular Disease: Pockets in the Colon
Diverticular disease involves the formation of small pouches, called diverticula, in the wall of the colon. Diverticulosis is the presence of these pouches, and diverticulitis occurs when these pouches become inflamed or infected.
How diverticular disease leads to rectal bleeding: Sometimes, these diverticula can bleed. This bleeding can range from mild to severe. Diverticular bleeding is often painless but can involve a significant amount of blood. Diverticulitis, when the pouches are inflamed, can also cause bleeding, along with abdominal pain and other symptoms.
Types of diverticular bleeding:
- Diverticulitis with rectal bleeding: Moderate bleeding, often stops on its own, accompanied by pain, nausea, and fever.
- Diverticular bleeding: Painless, large volume of bright red blood from the rectum.
Seeking medical attention: Any rectal bleeding associated with diverticular disease, especially diverticular bleeding due to the potential for significant blood loss, requires medical evaluation. Treatment may include antibiotics for diverticulitis and, in severe cases, surgery.
4. Proctitis and Colitis: Inflammation of the Rectum and Colon
Proctitis is inflammation of the rectum lining, and colitis is inflammation of the colon lining. Ulcerative colitis, a specific type of colitis, can cause ulcers in the colon lining that bleed.
Causes of proctitis and colitis: These conditions can be caused by infections, inflammatory bowel diseases like Crohn’s disease and ulcerative colitis, sexually transmitted infections, certain medications, radiation therapy, or reduced blood flow.
Symptoms and bleeding: Both proctitis and colitis can cause rectal bleeding, along with pain, diarrhea, and urgency to have bowel movements. Ulcerative colitis can result in more significant bleeding due to the ulcers.
Treatment: Treatment varies depending on the cause and can include antibiotics, anti-inflammatory medications, or surgery in severe cases.
5. Gastroenteritis: Infections Affecting the Digestive Tract
Gastroenteritis, often caused by bacterial or viral infections, is inflammation of the stomach and intestines.
Gastroenteritis and bloody stool: Bacterial gastroenteritis can cause bloody diarrhea as the infection inflames the colon. Viral gastroenteritis is less likely to cause bloody diarrhea.
Treatment: Treatment usually focuses on supportive care like fluids and rest. Antibiotics or antivirals might be used depending on the cause.
6. Sexually Transmitted Infections (STIs): Affecting the Rectum
STIs transmitted through anal intercourse can cause proctitis (inflammation of the rectum), increasing the risk of bleeding.
STIs and rectal bleeding: Infections like gonorrhea, chlamydia, and herpes can inflame the rectal lining, leading to bleeding and discharge.
Treatment: Treatment for STIs depends on the specific infection and typically involves antibiotics, antivirals, or antifungals.
7. Rectal Prolapse: When the Rectum Protrudes
Rectal prolapse occurs when part of the rectum pushes through the anus. This is often due to weakened pelvic floor muscles.
Prolapse and bleeding: Rectal prolapse can cause pain and bleeding as the protruding rectal tissue becomes irritated.
Treatment: Surgery is usually required to correct rectal prolapse.
8. Polyps: Growths in the Colon and Rectum
Polyps are abnormal tissue growths in the colon or rectum. While most are benign, some can become cancerous over time.

Polyps and bleeding: Polyps can irritate the lining of the colon or rectum and cause minor bleeding.
Detection and removal: Polyps are often detected and removed during routine colonoscopies.
9. Colon and Rectal Cancer: A Serious Consideration
Colon and rectal cancers can cause bleeding as the tumor grows and irritates the intestinal lining.
Cancer and rectal bleeding: Bleeding from colorectal cancer can be bright red or cause dark stools. It’s a significant symptom that requires prompt medical attention.
Importance of early detection: Colon and rectal cancers are often treatable, especially when detected early through screenings like colonoscopies.
10. Internal Bleeding: Bleeding Higher in the Digestive Tract
Bleeding originating higher in the gastrointestinal tract (like the stomach or small intestine) can also manifest as rectal bleeding.
Internal bleeding and rectal blood: Blood from higher up in the digestive tract may appear darker by the time it reaches the rectum.
Medical evaluation: Any suspected internal bleeding requires immediate medical attention to determine the source and cause.
When to Seek Medical Advice
While occasional, minor rectal bleeding might be due to something like hemorrhoids or a fissure, it’s crucial to know when to seek medical help.
Consult a doctor if you experience:
- Any rectal bleeding, even if it seems minor.
- Bleeding that is persistent or worsens.
- Large amounts of blood.
- Dizziness or weakness along with rectal bleeding.
- Changes in bowel habits, such as new constipation or diarrhea.
- Abdominal pain associated with rectal bleeding.
- Unexplained weight loss.
- Family history of colon cancer or inflammatory bowel disease.
A doctor can properly diagnose the cause of your rectal bleeding and recommend appropriate treatment. They may perform a physical exam, order blood tests, stool tests, or procedures like a colonoscopy to visualize the colon and rectum.
Conclusion
Finding blood when you wipe can be concerning, but understanding the potential causes can empower you to take appropriate action. While hemorrhoids and anal fissures are common and often manageable, rectal bleeding can also be a symptom of more serious conditions. It’s always best to consult with a healthcare professional to determine the cause of your rectal bleeding and ensure you receive the necessary care. Early diagnosis and treatment are key to managing any underlying health issue and maintaining your well-being.
