Rectal Bleeding: Causes and When to Seek Help

Rectal bleeding

Doctor, I have been experiencing rectal bleeding for the past two weeks, and the blood is bright red.
I have had similar experiences before, and it took almost two weeks of medication for it to resolve.
Sometimes, there is also blood dripping from the stool at the end.
After experiencing bleeding from constipation once, I now notice bleeding every time I exert myself during a bowel movement.
Is this something I should be concerned about?

This situation likely indicates a higher possibility of hemorrhoidal bleeding.
As long as there is no further bleeding, it should not be a concern.
It is recommended to avoid constipation during this period and to shorten the time spent on bowel movements.
You may also purchase over-the-counter hemorrhoid suppositories for use.
However, if bleeding persists, it is advisable to consult a physician for evaluation.

More Info

Rectal bleeding can be a concerning symptom, and it is essential to understand its potential causes and when to seek medical attention. The bright red color of the blood you are experiencing typically indicates that the bleeding is coming from the lower gastrointestinal tract, such as the rectum or anus. Common causes of rectal bleeding include hemorrhoids, anal fissures, diverticular disease, and colorectal polyps or cancer.
1. Hemorrhoids: These are swollen veins in the lower rectum or anus that can cause bleeding, especially during bowel movements. They are often associated with straining during defecation, which can lead to discomfort and bright red blood on the toilet paper or in the stool.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can be very painful and may also result in bright red blood.

3. Diverticular Disease: This condition involves the formation of small pouches in the colon wall, which can become inflamed or bleed.

4. Colorectal Polyps or Cancer: While less common, rectal bleeding can also be a sign of more serious conditions, such as polyps or colorectal cancer. This is particularly concerning if you have a family history of colorectal cancer or if you are over the age of 50.

Given that you have experienced this bleeding for two weeks and have a history of constipation, it is crucial to consult a healthcare professional. They may recommend a physical examination, possibly including a digital rectal exam, and further diagnostic tests such as a colonoscopy to identify the exact cause of the bleeding.
It is also important to address the constipation that may be contributing to your symptoms. Increasing your dietary fiber intake, staying hydrated, and possibly using over-the-counter stool softeners or laxatives can help alleviate constipation and reduce the risk of further bleeding.

In summary, while some causes of rectal bleeding, such as hemorrhoids or fissures, may be benign and manageable, persistent or recurrent bleeding should not be ignored. It is advisable to seek medical attention to rule out any serious underlying conditions and to receive appropriate treatment. Early intervention can lead to better outcomes and prevent complications.
