Rectal Health: What to Know About Blood in Stool - Surgery

Red stools?


Hello doctor, I've been seeing more and more about colorectal cancer online lately, and it's making me increasingly anxious.
I have mild diverticular disease, and because I'm overweight, I'm worried about my health.
Yesterday, I went to see a doctor for clarification.
After the consultation, the doctor began examining my anus, and I don't know what he inserted, but it was very painful.
He said the color looked normal and there were no significant issues.
The diagnosis report mentioned a sigmoidoscopy.
What is that? He said I only have irritable bowel syndrome.
I requested the doctor to conduct a fecal occult blood test.
Is it accurate to collect the stool sample about two days after the doctor examined me? I'm concerned that the doctor might have injured my anus during the examination.

Question two: This morning, when I had a bowel movement, I noticed a long, golden-yellow stool with segments, but when I wiped, I found two small red spots on the toilet paper.
I recalled that I had a sandwich with large tomato slices yesterday morning.
Could that be tomato residue? This is the first time I've experienced this situation.

1.
The fecal occult blood test should ideally be performed on stool samples that do not have visible blood.
Whether or not a colonoscopy has been performed does not affect the results, unless there is significant bleeding during or after the procedure.

2.
It is indeed possible that the presence of blood is due to undigested food residue.

More Info


Understanding rectal health and the presence of blood in stool is crucial, especially given the rising awareness of colorectal cancer. Your concerns are valid, and it’s good that you are seeking medical advice. Let’s break down your situation and address your questions.


What is a Colonoscopy?
A colonoscopy is a procedure that allows a doctor to examine the inner lining of your large intestine (colon) and rectum. During this procedure, a long, flexible tube with a camera (colonoscope) is inserted into the rectum. This allows the doctor to look for abnormalities, such as polyps or signs of cancer. It is a common procedure for diagnosing issues related to bowel health, including inflammatory bowel disease, colorectal cancer, and other gastrointestinal conditions.


Your Recent Experience
You mentioned experiencing pain during the examination. It’s not uncommon for patients to feel discomfort during a rectal examination or colonoscopy, especially if they are anxious or if there is any underlying irritation. However, if the pain was severe, it’s important to communicate this to your healthcare provider, as they may need to adjust their technique or consider other factors.


Blood in Stool
Finding blood in your stool can be alarming. The presence of bright red blood may indicate bleeding from the lower gastrointestinal tract, such as hemorrhoids or anal fissures, while darker blood can suggest bleeding from higher up in the digestive tract. The small red spots you noticed on the toilet paper could indeed be remnants of food, such as tomato skin, especially if you recently consumed a sandwich with tomatoes. However, it’s essential to monitor this symptom closely.


Timing of Stool Sample Collection
Regarding your question about the timing of your stool sample collection, it is generally advisable to collect the sample as soon as possible after noticing any concerning symptoms. If you collected the sample two days after your examination, it may still be valid, but the timing can affect the results. If you experience any further symptoms or if the blood reappears, you should inform your doctor immediately.


Recommendations
1. Follow-Up: Since your doctor mentioned that you might have irritable bowel syndrome (IBS), it’s essential to follow up on this diagnosis. IBS can cause symptoms like abdominal pain, bloating, and changes in bowel habits, but it typically does not cause blood in the stool. If you continue to see blood, you should seek further evaluation.

2. Dietary Considerations: Pay attention to your diet. Foods high in fiber can help regulate bowel movements and may alleviate symptoms of IBS. However, if you notice that certain foods trigger your symptoms, consider keeping a food diary to identify potential culprits.

3. Regular Screenings: Given your concerns about colorectal cancer, ensure that you are up to date with screenings, especially if you have risk factors such as obesity. The American Cancer Society recommends that individuals at average risk begin screening at age 45, but those with additional risk factors may need to start earlier.

4. Communication with Your Doctor: Always communicate openly with your healthcare provider about your symptoms, concerns, and any discomfort you experience during examinations. They are there to help you and can provide reassurance or further testing as needed.


Conclusion
In summary, while your recent examination and the findings may not indicate a serious issue, it’s crucial to remain vigilant about any changes in your health. Blood in the stool should always be evaluated, and regular check-ups are essential for maintaining rectal health. If you have any further questions or if your symptoms persist, don’t hesitate to reach out to your healthcare provider for guidance. Your health is paramount, and being proactive is the best approach.
