Rectal bleeding


Hello Doctor, I have been experiencing irregular eating habits, which led to nearly a week without a bowel movement.
I neglected this issue until last week when I had extreme difficulty passing stool.
I managed to push through the discomfort and eventually expelled the stool, but it was very uncomfortable at the time.
A week has passed, and I have increased my intake of fruits and vegetables, which has improved my bowel movements significantly, and I am now having regular daily bowel movements.
However, the pain from the injury caused during that time is still lingering.
I noticed some bleeding during my last bowel movement, and I am experiencing persistent pain in the anal area.
Although it does not interfere with my daily activities, I am extremely worried.
The amount of bleeding was somewhat significant, and there were noticeable blood clots on the toilet paper, which has made me very anxious.
I hope the doctor can provide some guidance.

Hello: The possibility of bleeding from an internal mole is higher.
Eating more vegetables and fruits can be beneficial.
Please consult the Department of Gastroenterology at Changhua Hospital, Ministry of Health and Welfare for further assistance.

More Info


Rectal bleeding can be a concerning symptom, and it’s important to understand its potential causes, associated symptoms, and when to seek medical help. Based on your description, it seems you have experienced a combination of constipation and subsequent straining during bowel movements, which can lead to several issues, including anal fissures or hemorrhoids.


Causes of Rectal Bleeding
1. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard or large stools. They can result in sharp pain during and after bowel movements and may lead to bleeding, which typically appears bright red.

2. Hemorrhoids: Swollen blood vessels in the rectal area can cause bleeding, especially during straining. Hemorrhoids can be internal or external, and while they may cause discomfort, they are usually not serious.

3. Diverticular Disease: This condition involves small pouches that can form in the colon wall, which may become inflamed or infected, leading to bleeding.

4. Gastrointestinal Conditions: Other conditions such as inflammatory bowel disease (IBD), colorectal polyps, or even colorectal cancer can also cause rectal bleeding, although these are less common in younger individuals.


Symptoms to Watch For
- Pain: As you mentioned, pain during bowel movements can indicate an anal fissure or hemorrhoids. If the pain is severe or persists, it’s worth consulting a healthcare provider.


- Blood Characteristics: Bright red blood typically indicates bleeding from the lower gastrointestinal tract, while darker blood may suggest a source higher up in the digestive system.

- Changes in Bowel Habits: Any significant changes in your bowel habits, such as persistent constipation or diarrhea, should be evaluated.

- Associated Symptoms: Fever, weight loss, or changes in appetite accompanying rectal bleeding warrant immediate medical attention.


When to Seek Help
You should seek medical attention if:
- The bleeding persists or worsens.

- You experience significant pain or discomfort.

- You notice blood mixed with stool or dark, tarry stools.

- There are any signs of infection, such as fever or chills.

- You have a history of gastrointestinal issues or family history of colorectal cancer.


Management and Recovery
Given that you have already improved your diet and are experiencing more regular bowel movements, it’s a positive step towards recovery. However, the presence of ongoing pain and bleeding suggests that you should consider the following:
1. Increase Fiber Intake: Continue to consume a high-fiber diet, which can help soften stools and reduce straining. Foods like fruits, vegetables, whole grains, and legumes are beneficial.

2. Hydration: Ensure you are drinking plenty of water to help with digestion and stool formation.

3. Over-the-Counter Treatments: You may consider using topical treatments for hemorrhoids or fissures, such as hydrocortisone creams or witch hazel pads, which can alleviate discomfort.

4. Warm Baths: Soaking in a warm bath can help relax the anal muscles and relieve pain.

5. Avoid Straining: When you feel the urge to go, try not to delay. Straining can exacerbate the issue.

6. Consult a Healthcare Provider: If symptoms persist, it is crucial to consult a healthcare provider for a thorough examination. They may recommend further diagnostic tests, such as a colonoscopy, to rule out any serious conditions.

In summary, while your symptoms may be related to anal fissures or hemorrhoids due to previous constipation, it’s essential to monitor your condition closely. If the bleeding continues or worsens, or if you experience any alarming symptoms, do not hesitate to seek medical advice. Early intervention can help prevent complications and ensure proper healing.
