Rectal bleeding


I noticed a significant amount of bright red blood in my stool over the past two days, both in the toilet and when wiping, similar to the feeling during menstruation, but my bowel movements have been smooth.
I also experienced blood during urination once.
If it were hemorrhoids, why would there be blood during urination as well? 😭😭

Hello: Blood in the stool is considered an abnormal symptom and can be diagnosed from common conditions like hemorrhoids to more serious gastrointestinal diseases.
Based on your description, the likelihood of hemorrhoidal bleeding is the highest.
Straining during urination can increase pelvic pressure, which may also lead to hemorrhoidal bleeding.
It is recommended that you visit a gastroenterology department for further examination.

More Info


When you notice fresh blood in your stool, it can understandably be alarming and raise concerns about your health. The presence of blood can stem from various causes, some of which are benign, while others may require immediate medical attention. Here’s a breakdown of potential causes, along with guidance on when to seek help.


Potential Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of bright red blood during bowel movements is hemorrhoids. These swollen blood vessels in the rectum or anus can bleed, especially during straining. However, hemorrhoids typically do not cause blood in urine.

2. Anal Fissures: Small tears in the lining of the anus can occur, often due to passing hard stools. This can lead to bleeding and pain during bowel movements.

3. Diverticular Disease: Diverticulosis, which involves small pouches forming in the colon wall, can lead to diverticulitis if these pouches become inflamed or infected. This condition can cause bleeding.

4. Gastrointestinal Conditions: Conditions such as inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, can lead to bloody stools. These diseases are often accompanied by other symptoms like abdominal pain and diarrhea.

5. Polyps or Colorectal Cancer: Polyps are growths on the colon lining that can bleed. Some polyps can develop into cancer over time. Colorectal cancer can also present with blood in the stool, especially in later stages.

6. Infections: Certain infections, particularly those affecting the gastrointestinal tract, can lead to bloody diarrhea. Bacterial infections, such as those caused by E. coli or Salmonella, may also present with blood.

7. Urinary Tract Issues: The presence of blood in urine (hematuria) can indicate a separate issue, such as a urinary tract infection (UTI), kidney stones, or other kidney-related problems. It is unusual for hemorrhoids to cause blood in urine.


When to Seek Help
Given your symptoms of fresh blood in your stool and urine, it is essential to seek medical attention promptly. Here are some guidelines on when to see a doctor:
- Immediate Care: If you experience significant amounts of blood in your stool or urine, or if you feel faint, dizzy, or have a rapid heartbeat, seek emergency care.

- Persistent Symptoms: If the bleeding continues over a few days, or if you notice other symptoms such as severe abdominal pain, changes in bowel habits, or unexplained weight loss, schedule an appointment with your healthcare provider.

- Urinary Symptoms: Since you mentioned blood in your urine, it is crucial to discuss this with a doctor as well. Blood in urine can indicate a urinary tract infection, kidney stones, or other serious conditions.


Diagnostic Steps
When you visit a healthcare provider, they may perform several diagnostic tests, including:
- Physical Examination: A thorough examination to check for hemorrhoids or other visible issues.

- Blood Tests: To evaluate your overall health and check for anemia or infection.

- Stool Tests: To identify any infections or blood in the stool.

- Imaging Studies: Such as a CT scan or ultrasound, to visualize the organs involved.

- Endoscopy: A colonoscopy may be recommended to directly examine the colon and rectum.


Conclusion
While the presence of blood in your stool and urine can be concerning, many causes are treatable. It is essential to consult with a healthcare professional to determine the underlying cause and receive appropriate treatment. Do not hesitate to reach out for help, as early intervention can significantly improve outcomes.
