Rectal bleeding


Hello Doctor: Last September, I underwent hemorrhoid ligation due to internal hemorrhoids, and everything was fine afterward.
However, in the past few days, I've noticed a few drops of blood after each bowel movement, and it seems like there is a small amount of tissue protruding near the anus.
I would like to ask the doctor: Is this situation related to hemorrhoids again, or could there be another cause?

Dr. Hou Yongji reply Surgery


Hello: Please return to the clinic at your earliest convenience for an examination to determine if it is hemorrhoids again or if there are other conditions.
Wishing you good health!

More Info


Rectal bleeding can be a concerning symptom, and it's important to understand its potential causes and when to seek medical help. Based on your description, it seems that you have a history of hemorrhoids (internal hemorrhoids), which could indeed be the cause of the bleeding you are experiencing now. However, there are several factors to consider when evaluating rectal bleeding.


Possible Causes of Rectal Bleeding
1. Hemorrhoids: As you mentioned, hemorrhoids are a common cause of rectal bleeding. They can be internal (inside the rectum) or external (under the skin around the anus). If you had a procedure for hemorrhoids in the past, it is possible that new hemorrhoids have developed or that the previous ones have recurred.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to sharp pain during bowel movements and may also cause bleeding.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon, can lead to diverticulitis (inflammation of these pouches) and can cause rectal bleeding.

4. Colorectal Polyps or Cancer: While less common, polyps (growths on the colon lining) can bleed, and some can develop into cancer. It's important to monitor any changes in your bowel habits or bleeding patterns.

5. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation in the digestive tract, leading to bleeding.

6. Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract.


When to Seek Medical Help
You should seek medical attention if you experience any of the following:
- Significant Bleeding: If you notice a large amount of blood, or if the bleeding persists.

- Changes in Bowel Habits: If you experience changes in your bowel habits, such as diarrhea or constipation, especially if accompanied by blood.

- Severe Pain: If you have severe pain in the rectal area or during bowel movements.

- Other Symptoms: If you experience symptoms such as fever, weight loss, or changes in appetite.


Recommended Actions
1. Consult a Healthcare Provider: Given your history of hemorrhoids and the current symptoms, it is advisable to consult a healthcare provider, preferably a gastroenterologist or a colorectal surgeon. They can perform a thorough examination, which may include a digital rectal exam or a colonoscopy, to determine the exact cause of the bleeding.

2. Dietary Adjustments: To prevent constipation and reduce straining during bowel movements, consider increasing your fiber intake through fruits, vegetables, and whole grains. Staying hydrated is also essential.

3. Avoid Straining: When using the bathroom, try to avoid straining, as this can exacerbate hemorrhoids and lead to further bleeding.

4. Topical Treatments: Over-the-counter creams or ointments designed for hemorrhoids may provide relief from discomfort and help with healing.

5. Monitor Symptoms: Keep track of your symptoms, including the frequency and amount of bleeding, as well as any associated pain or changes in bowel habits. This information will be helpful for your healthcare provider.

In conclusion, while your symptoms may be related to hemorrhoids, it is crucial to rule out other potential causes of rectal bleeding. Seeking medical advice is the best course of action to ensure proper diagnosis and treatment.
