Rectal bleeding during bowel movements?
Hello, Dr.
Chang.
I've been experiencing a burning and itching sensation around my anus for the past couple of days.
My stools have been somewhat soft, and after bowel movements, I've noticed dark red liquid on the toilet paper, but it is not thick.
Could this be an issue related to my intestines or anus? Thank you, doctor.

There are three common causes of rectal bleeding: 1.
Anal fissures or skin abrasions, characterized by a small amount of blood accompanied by a sharp pain at the site of the wound.
2.
Ruptured thrombosed hemorrhoids, which typically produce slightly more blood than the first cause, usually occurring after straining during bowel movements, and may be painless or cause only mild discomfort.
3.
Gastrointestinal bleeding related to conditions such as polyps, ulcers, or tumors, which presents with darker blood and may be associated with changes in bowel habits or abdominal symptoms; this is less common in younger individuals.
Based on your age and symptoms, causes 1 or 2 are more likely.
However, if you are genuinely concerned about gastrointestinal issues, you may discuss with a gastroenterologist or a colorectal surgeon the possibility of scheduling a colonoscopy.

Rectal bleeding can be a concerning symptom, and it's important to understand the potential causes and when to seek medical attention. Based on your description of experiencing a burning and itching sensation around the anus, along with soft stools and dark red liquid on toilet paper after wiping, there are several possible explanations for your symptoms.
1. Hemorrhoids: One of the most common causes of rectal bleeding is hemorrhoids, which are swollen veins in the lower rectum or anus. They can cause discomfort, itching, and bleeding, especially during bowel movements. The blood from hemorrhoids is usually bright red and may appear on the toilet paper or in the toilet bowl.
2. Anal Fissures: Another possibility is an anal fissure, which is a small tear in the lining of the anus. This can occur due to passing hard stools or straining during bowel movements. Fissures can cause sharp pain and bleeding, often seen as bright red blood on the toilet paper.
3. Infections or Inflammatory Conditions: Conditions such as anal abscesses or infections can also lead to rectal bleeding. Inflammatory bowel diseases (IBD) like Crohn's disease or ulcerative colitis can cause similar symptoms, including rectal bleeding, abdominal pain, and changes in bowel habits.
4. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis if these pouches become inflamed or infected. This condition can cause bleeding and abdominal discomfort.
5. Polyps or Colorectal Cancer: While less common, rectal bleeding can also be a sign of polyps or colorectal cancer, especially if there are other symptoms such as changes in bowel habits, weight loss, or abdominal pain.
Given that you mentioned the blood is dark red and not thick, it suggests that the bleeding may be coming from the lower part of the gastrointestinal tract, such as the rectum or anus, rather than from higher up in the colon. However, the presence of any rectal bleeding warrants a thorough evaluation by a healthcare professional.
Recommendations:
- Seek Medical Attention: It is advisable to consult a healthcare provider, especially if the bleeding persists, increases in volume, or is accompanied by other concerning symptoms such as severe pain, fever, or changes in bowel habits.
- Avoid Straining: If hemorrhoids or fissures are suspected, try to avoid straining during bowel movements. Increasing fiber intake and staying hydrated can help soften stools and reduce the risk of further injury.
- Topical Treatments: Over-the-counter creams or ointments may provide relief from itching and discomfort associated with hemorrhoids or fissures.
- Keep a Symptom Diary: Documenting your symptoms, including the frequency and amount of bleeding, any associated pain, and dietary habits, can help your healthcare provider make a more accurate diagnosis.
In conclusion, while there are several potential causes for rectal bleeding, it is crucial to have a proper evaluation to determine the underlying issue. Early diagnosis and treatment can prevent complications and improve your overall health.
