Rectal bleeding


Hello, I just turned 20 this year and I would like to ask about a recent situation of rectal bleeding.
A year ago, I went to the hospital due to abdominal discomfort, and they mentioned that I had intestinal inflammation.
Later, it was diagnosed as irritable bowel syndrome because I had a stool occult blood test that came back normal.
The doctor suggested it might be irritable bowel syndrome, and I later suspected I had hemorrhoids.
I often feel like I can't clean myself properly after a bowel movement, and I have itching around the anus.
Recently, my abdomen has started to feel uncomfortable again, and I noticed pinkish blood sinking in the water after a bowel movement, but the stool itself was golden yellow.
Today, for the first time, I wiped and found dark red blood.
Should I go to the hospital for a colonoscopy, or could this just be bleeding from hemorrhoids? I'm not sure if I have internal or external hemorrhoids.

Blood in the stool or changes in bowel habits, including alterations in stool shape or consistency, are abnormal gastrointestinal function changes.
These symptoms can range from common hemorrhoids to other serious gastrointestinal diseases.
Based on your description, hemorrhoidal bleeding is the most likely cause; however, it is still recommended that you visit a gastroenterologist for further evaluation to determine if a colonoscopy is necessary.

Rectal bleeding can be a concerning symptom, and it's important to understand when to seek medical attention. Given your history of gastrointestinal issues, including inflammation and irritable bowel syndrome (IBS), along with your recent symptoms, it's wise to approach this situation with caution.

Firstly, the presence of blood in your stool or when wiping can arise from various causes. The fact that you are experiencing bright red blood on the toilet paper and dark red blood can indicate different issues. Bright red blood typically suggests that the bleeding is coming from the lower part of the gastrointestinal tract, such as the rectum or anus, while darker blood may indicate bleeding from higher up in the digestive tract.

In your case, since you have a history of gastrointestinal discomfort and potential hemorrhoids, it's possible that the bleeding could be related to hemorrhoids, especially if you are experiencing itching and discomfort around the anal area. Hemorrhoids can be internal or external, and they often cause bleeding during bowel movements, particularly if there is straining involved.

However, given your symptoms of abdominal discomfort and the changes in your bowel habits, it is crucial to consider other potential causes of rectal bleeding. Conditions such as anal fissures, diverticular disease, inflammatory bowel disease (IBD), or even colorectal polyps or cancer can also lead to rectal bleeding. While the likelihood of serious conditions may vary based on your age and medical history, it is always better to err on the side of caution.

Considering your situation, here are some recommendations:
1. Seek Medical Attention: It would be prudent to consult with a healthcare professional, especially a gastroenterologist, who can evaluate your symptoms more thoroughly. They may recommend a colonoscopy to visualize the colon and rectum directly, which can help identify the source of the bleeding.

2. Document Your Symptoms: Keep a record of your symptoms, including the frequency of bleeding, the color of the blood, any associated pain, and changes in your bowel habits. This information can be helpful for your doctor.

3. Avoid Straining: If you suspect hemorrhoids, try to avoid straining during bowel movements. Increasing your fiber intake through fruits, vegetables, and whole grains can help soften your stool and reduce the risk of further irritation.

4. Hydration: Ensure you are drinking plenty of water to stay hydrated, which can also aid in digestion and prevent constipation.

5. Monitor Your Condition: If you notice any worsening of symptoms, such as increased bleeding, severe abdominal pain, or changes in your bowel habits, seek medical attention immediately.

In summary, while it is possible that your symptoms are related to hemorrhoids, the presence of rectal bleeding warrants a thorough evaluation to rule out any serious underlying conditions. A colonoscopy is a common and effective diagnostic tool that can provide clarity and peace of mind. Don't hesitate to reach out to a healthcare provider to discuss your symptoms and determine the best course of action. Your health is important, and addressing these concerns early can lead to better outcomes.
