Rectal bleeding
Recently, I have been experiencing blood in my stool.
Sometimes I feel a dull pain in my abdomen, but it's not very severe; however, I do pass gas frequently, sometimes in succession.
The blood usually stops after wiping.
Could this be related to working night shifts? If these symptoms continue, should I consider getting a colonoscopy for further examination?

Dr. Ke Fangxu reply Surgery
Based on your description, it seems more like irritable bowel syndrome combined with mild hemorrhoidal bleeding.
It is recommended to start with a light diet and maintain a good daily routine.
Working night shifts may also have an impact.
If symptoms persist without improvement, you can ask a physician to prescribe medication.
If there is still no improvement or if you are very concerned, you may consider scheduling a colonoscopy.

More Info
Rectal bleeding can be a concerning symptom, and understanding its potential causes, associated symptoms, and when to seek medical help is crucial for your health.
Causes of Rectal Bleeding:
Rectal bleeding can arise from various conditions, some of which may be benign, while others could indicate more serious health issues. Common causes include:
1. Hemorrhoids: Swollen blood vessels in the rectum or anus can cause bleeding, especially during bowel movements. This is often accompanied by itching or discomfort.
2. Anal Fissures: Small tears in the lining of the anus can occur due to passing hard stools, leading to pain and bleeding.
3. Diverticular Disease: Diverticulosis, the presence of small pouches in the colon wall, can lead to diverticulitis, which may cause bleeding.
4. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation and bleeding in the digestive tract.
5. Polyps or Colorectal Cancer: Polyps are growths on the colon lining that can bleed. Some polyps may develop into cancer over time, which is why regular screening is important.
6. Gastrointestinal Infections: Certain infections can lead to inflammation and bleeding in the intestines.
7. Other Conditions: Conditions such as gastrointestinal ulcers, vascular malformations, or even systemic diseases can also lead to rectal bleeding.
Symptoms to Watch For:
In addition to rectal bleeding, you mentioned experiencing abdominal discomfort and increased flatulence. While occasional gas is normal, persistent or severe symptoms warrant further investigation. Other symptoms that may accompany rectal bleeding include:
- Changes in bowel habits (diarrhea or constipation)
- Abdominal cramps or pain
- Weight loss
- Fatigue or weakness
- Changes in the color or consistency of your stool
When to Seek Help:
You should seek medical attention if you experience any of the following:
- Significant or persistent rectal bleeding
- Blood in your stool that is bright red or dark and tarry
- Severe abdominal pain
- Symptoms of anemia (fatigue, weakness, pale skin)
- Changes in bowel habits that last more than a few days
Given your situation, where you experience rectal bleeding and abdominal discomfort, it is advisable to consult a healthcare professional. They may recommend a thorough evaluation, which could include a physical examination, blood tests, and possibly imaging studies.
Diagnostic Procedures:
A colonoscopy is a common procedure used to investigate rectal bleeding. It allows the doctor to visualize the interior of the colon and rectum, identify any abnormalities, and potentially take biopsies or remove polyps. Depending on your symptoms and medical history, your doctor may also consider other diagnostic tests, such as a flexible sigmoidoscopy or imaging studies like a CT scan.
Lifestyle Considerations:
You mentioned working night shifts, which can disrupt your circadian rhythm and potentially affect your digestive health. Irregular eating patterns, stress, and lack of sleep can contribute to gastrointestinal issues. Maintaining a balanced diet rich in fiber, staying hydrated, and managing stress can help improve your digestive health.
In summary, while rectal bleeding can stem from various causes, it is essential to take it seriously, especially if it persists or is accompanied by other concerning symptoms. Consulting a healthcare provider for a thorough evaluation and appropriate diagnostic testing is the best course of action to determine the underlying cause and receive proper treatment.
