Regarding rectal bleeding?


Hello, Doctor Yu.
I don't eat enough fruits and vegetables and I sit for long periods.
Three years ago, I had a colonoscopy that showed no issues except for hemorrhoids.
The doctor prescribed me oral medication and suppositories, but did not mention surgery, so I am unsure of the severity.
I experience occasional dry and hard stools, which cause a painful tearing sensation in the anus during bowel movements, making it quite torturous.
I have tried inserting my finger about 1 cm into the anus and felt something like broken skin; the anal area also hurts.
There is fresh blood on the toilet paper and in the toilet, which I believe is due to anal fissures.
A few days ago, this happened again.
Today, although my stool was not hard, the wound has not healed, and I was very careful, yet I still experienced a sudden sharp tearing pain.
There was a lot of blood on the toilet paper accompanied by some mucus, and I noticed more blood in the toilet than before, including a blood clot the size of a one-dollar coin.
Could you please tell me what this might indicate? Is this bleeding from an anal fissure, hemorrhoids, or could there be an issue with the rectum? What does the presence of a blood clot signify? Thank you for your response.

Rectal bleeding can be a concerning symptom for many patients, and understanding its potential causes is crucial for appropriate management and treatment. Based on your description, it seems that you are experiencing symptoms that could be related to anal fissures or hemorrhoids, both of which are common conditions that can lead to rectal bleeding.

Anal fissures are small tears in the lining of the anus, often caused by passing hard or large stools. Symptoms typically include sharp pain during and after bowel movements, and you may notice bright red blood on the toilet paper or in the toilet bowl. The fact that you have experienced a tearing sensation and have noted blood, especially in conjunction with hard stools, strongly suggests that you may indeed have an anal fissure. The presence of a "broken skin" sensation when you examine the area is also consistent with this diagnosis.

On the other hand, hemorrhoids, which are swollen veins in the rectal area, can also cause bleeding. They can be internal or external, and while internal hemorrhoids often present with painless bleeding, external hemorrhoids can be painful and may also lead to bleeding if they become thrombosed (develop a blood clot). The blood you see could be from either condition, and the presence of blood clots may indicate that there is significant irritation or trauma to the area.

The fact that you have noticed a blood clot the size of a coin is concerning and should not be ignored. While it may be related to your existing conditions, it is essential to rule out other potential causes of rectal bleeding, such as diverticular disease, colorectal polyps, or even more serious conditions like colorectal cancer, especially given your history of constipation and hard stools.

Here are some recommendations for managing your symptoms and improving your condition:
1. Increase Fiber Intake: A diet rich in fruits, vegetables, and whole grains can help soften your stools and make bowel movements easier. Aim for at least 25-30 grams of fiber per day.

2. Stay Hydrated: Drinking plenty of water can help prevent constipation and promote softer stools.

3. Avoid Straining: When you feel the urge to have a bowel movement, try to go as soon as possible. Straining can exacerbate fissures and hemorrhoids.

4. Warm Sitz Baths: Soaking in warm water for 10-15 minutes can help soothe the anal area and promote healing.

5. Topical Treatments: Over-the-counter creams or ointments designed for hemorrhoids can provide relief from pain and itching. If you suspect an anal fissure, topical anesthetics or hydrocortisone creams may also be beneficial.

6. Consult a Healthcare Provider: Given the severity of your symptoms, especially the presence of blood clots, it is essential to consult a healthcare provider. They may recommend a physical examination and possibly a colonoscopy to rule out other serious conditions.

7. Consider Medication: If dietary changes are insufficient, your doctor may prescribe stool softeners or laxatives to help ease bowel movements.

In conclusion, while your symptoms may be indicative of anal fissures or hemorrhoids, the presence of blood and blood clots warrants further evaluation by a healthcare professional. Early intervention can prevent complications and improve your quality of life. Please do not hesitate to seek medical attention to address your concerns and receive appropriate treatment.
