Blood in Stool: Causes and When to Seek Help

The stool is all blood and water?

Hello doctor, yesterday morning I experienced low blood sugar and discomfort in my stomach.
When I went to the bathroom, my diarrhea was of normal color, but a few hours later it was just blood.
Today, it is still bright red.
However, I have a constant feeling of hunger in my stomach.
I'm not sure if this could indicate gastrointestinal bleeding or if it’s just that I accidentally ruptured a hemorrhoid from straining too hard during diarrhea.

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 diarrhea during this period and to shorten the time spent on bowel movements.
Spicy and irritating foods should be temporarily avoided.
Intestinal bleeding generally occurs in older patients.
If bleeding persists, it is advisable to consult a physician.
If necessary, a colonoscopy can also be arranged.

More Info

When it comes to the presence of blood in stool, it is essential to understand that this symptom can arise from various causes, ranging from benign to serious conditions. The fact that you experienced normal bowel movements initially and then observed bright red blood in your stool raises several considerations.

Possible Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of bright red blood in the stool is hemorrhoids, which are swollen blood vessels in the rectal area. If you have been straining during bowel movements, this could lead to the rupture of hemorrhoids, resulting in bleeding. The blood from hemorrhoids is usually bright red and may be seen on the toilet paper or in the toilet bowl.

2. Anal Fissures: Similar to hemorrhoids, anal fissures can occur due to straining or passing hard stools. These small tears in the lining of the anus can cause sharp pain and bleeding during bowel movements.

3. Gastrointestinal Bleeding: More serious conditions such as diverticulosis, inflammatory bowel disease (IBD), or colorectal cancer can also lead to blood in the stool. In these cases, the blood may not always be bright red; it can also appear darker or mixed with the stool.

4. Infections: Certain gastrointestinal infections can cause bloody diarrhea, often accompanied by other symptoms such as abdominal pain, fever, or vomiting.
5. Other Conditions: Conditions such as peptic ulcers or gastrointestinal tumors can also lead to bleeding, although the blood may not always be visible in the stool.

When to Seek Medical Help
Given your symptoms, it is crucial to seek medical attention, especially since you have observed a significant change in your stool color and consistency. Here are some guidelines on when to seek help:
- Persistent Symptoms: If the blood in your stool continues or worsens, it is essential to consult a healthcare provider.

- Accompanying Symptoms: If you experience additional symptoms such as severe abdominal pain, fever, dizziness, or fainting, seek immediate medical care.

- Duration: If the bleeding persists for more than a couple of days, it is advisable to get evaluated by a doctor.

Diagnostic Approach
When you visit a healthcare provider, they may perform several diagnostic tests, including:
- Physical Examination: A thorough examination to check for signs of hemorrhoids or fissures.

- Blood Tests: To assess for anemia or infection.

- Stool Tests: To check for the presence of blood or pathogens.

- Imaging Studies: Such as a colonoscopy or CT scan, may be necessary to visualize the gastrointestinal tract and identify the source of bleeding.

Conclusion
While it is possible that your symptoms are due to a benign condition such as hemorrhoids or an anal fissure, it is essential to rule out more serious causes. Blood in the stool should never be ignored, and timely medical evaluation is crucial for proper diagnosis and treatment. If you are experiencing ongoing symptoms or any concerning signs, please do not hesitate to seek medical attention. Your health and well-being are paramount, and early intervention can lead to better outcomes.
