Rectal bleeding


Hello, doctor.
I have been experiencing rectal bleeding for the past few days.
I notice bright red blood on the toilet paper after wiping, whereas previously, I only saw blood in my stool.
Recently, I have also noticed bleeding when I exert myself slightly while using the toilet.
I feel a bit of pain during bowel movements, and my stools are somewhat hard.
Occasionally, I also experience itching around the anus.
What could this be more similar to? Thank you.

Hello: The common causes of rectal bleeding, pain, and itching around the anus include hemorrhoids, anal fissures, polyps, ulcers, and tumors.
It is recommended to follow up with a colorectal specialist for further examination.
Rectal bleeding is not normal; prolonged bleeding can lead to chronic anemia, palpitations, and dizziness, which should not be ignored.
Wishing you safety and health! Dr.

More Info


Blood in stool can be a concerning symptom, and it’s important to understand the potential causes and when to seek medical attention. Based on your description, it seems that you are experiencing bright red blood on the toilet paper after wiping, as well as blood mixed with your stool, accompanied by some pain and hard stools. These symptoms can be indicative of several conditions, and I will outline some common causes and recommendations for when to seek help.


Common Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of bright red blood on the toilet paper is hemorrhoids. These are swollen veins in the lower rectum or anus that can cause pain, itching, and bleeding, especially during bowel movements. The blood is usually bright red and may appear on the stool or toilet paper.

2. Anal Fissures: An anal fissure is a small tear in the lining of the anus, often caused by passing hard stools. This can lead to sharp pain during bowel movements and bright red blood on the stool or toilet paper.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis if these pouches become inflamed. This condition can cause bleeding and changes in bowel habits.

4. Colorectal Polyps or Cancer: While less common, polyps (growths on the colon lining) and colorectal cancer can also present with blood in the stool. This is more likely if there are other symptoms such as weight loss, changes in bowel habits, or a family history of colorectal cancer.

5. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract, leading to blood in the stool.


When to Seek Medical Help
You should seek medical attention if you experience any of the following:
- Persistent Bleeding: If the bleeding continues or worsens, it’s important to consult a healthcare provider.

- Severe Pain: If you experience significant pain during bowel movements or at other times, this warrants evaluation.

- Changes in Bowel Habits: Any sudden changes in your bowel habits, such as diarrhea or constipation, should be discussed with a doctor.

- Other Symptoms: If you experience additional symptoms such as fever, weight loss, or fatigue, these could indicate a more serious condition.


Recommendations
1. Dietary Changes: To help with hard stools, consider increasing your fiber intake through fruits, vegetables, and whole grains. Staying hydrated is also crucial, as it can help soften stools.

2. Over-the-Counter Remedies: You might find relief with over-the-counter treatments for hemorrhoids or stool softeners to ease bowel movements.

3. Consult a Healthcare Provider: Given your symptoms, it would be wise to schedule an appointment with a healthcare provider. They may perform a physical examination and possibly recommend further tests, such as a colonoscopy, to determine the cause of the bleeding.

4. Avoid Straining: When using the bathroom, try to avoid straining, as this can exacerbate hemorrhoids and fissures.

In conclusion, while some causes of blood in the stool are benign, it’s essential to take this symptom seriously, especially given the changes you’ve described. Early evaluation and treatment can help prevent complications and address any underlying issues effectively. Please do not hesitate to reach out to a healthcare professional for personalized advice and care.
