Blood in stool


Hello, doctor.
Recently, I experienced diarrhea after eating very spicy food, and the next day my stool had mucus with streaks of blood, but it only happened once.
After that, I occasionally notice sedimentary blood in my stool; if I don't look closely, it's hard to tell it's blood because the color is very dark and sedimentary.
I haven't had any diarrhea or constipation issues since then, and my stool is generally soft.
However, I'm still a bit worried because there is still occasional blood, and I feel like it doesn't resemble the symptoms of ulcerative colitis.
I'm afraid it might get worse.

At the age of 25, the likelihood of developing colorectal cancer is not zero, but generally speaking, it is very, very low.
Based on your description, it seems more likely that you are experiencing inflammation of the intestines due to consuming excessively spicy food, along with mild hemorrhoidal bleeding.
It is recommended to follow a bland diet and maintain a good lifestyle.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you may want to consult a physician for medication or to undergo a colonoscopy.

More Info


Blood in the stool can be a concerning symptom, and it’s important to understand the potential causes and when to seek medical help. In your case, you mentioned experiencing diarrhea after consuming spicy food, followed by the presence of mucus with blood in your stool. This can be alarming, but let’s break down the possible reasons and what actions you should consider.


Possible Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of blood in the stool is hemorrhoids, which are swollen blood vessels in the rectum or anus. They can cause bright red blood on the stool or toilet paper, especially after straining during bowel movements.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to bleeding and significant pain during bowel movements.

3. Gastrointestinal Infections: Infections from bacteria, viruses, or parasites can lead to inflammation of the intestines, resulting in diarrhea and blood in the stool. This could be related to your recent experience with spicy food, which may have irritated your gastrointestinal tract.

4. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause inflammation in the digestive tract, leading to symptoms like diarrhea, abdominal pain, and blood in the stool.

5. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon, can sometimes lead to diverticulitis, where these pouches become inflamed or infected, causing bleeding.

6. Polyps or Colorectal Cancer: While less common, polyps in the colon can bleed, and in some cases, they can be precursors to colorectal cancer. Blood in the stool, especially if it is dark or tarry, can indicate bleeding from higher up in the gastrointestinal tract.


When to Seek Medical Help
Given that you have noticed blood in your stool intermittently, it is advisable to consult a healthcare professional. You should seek immediate medical attention if you experience any of the following:
- Heavy Bleeding: If you notice a significant amount of blood or if it is accompanied by clots.

- Severe Abdominal Pain: If you experience intense pain that does not subside.

- Changes in Bowel Habits: If you develop persistent diarrhea or constipation.

- Signs of Anemia: Such as fatigue, weakness, or shortness of breath, which could indicate significant blood loss.

- Fever: If you develop a fever, which could indicate an infection.


Diagnostic Steps
When you visit a healthcare provider, they may perform several diagnostic tests, including:
- Physical Examination: To check for signs of hemorrhoids or fissures.

- Blood Tests: To assess for anemia or infection.

- Stool Tests: To check for infections or blood.

- Colonoscopy: If necessary, to visualize the colon and identify any abnormalities.


Conclusion
While the presence of blood in your stool can be alarming, it is essential to approach the situation calmly and seek medical advice. Early diagnosis and treatment can help address any underlying issues effectively. Given your symptoms and concerns, I recommend scheduling an appointment with a healthcare provider to discuss your symptoms in detail and undergo appropriate testing. This will provide you with peace of mind and ensure that any potential health issues are addressed promptly.
