Blood in Stool: Causes and When to Seek Medical Help

Is it blood in the stool?

Hello, I am a senior high school student.
Recently, I have been staying up late, and today while having a bowel movement, I unexpectedly noticed some bright red blood, but it was a small amount.
Since I have never experienced anything like this before, I haven't paid much attention to my stools, although I do recall that they have been smellier than usual lately.
The day before, I had spicy braised food, and I have been eating it about once a week for the past two months.
There have been one or two instances where I noticed a little blood on the toilet paper after wiping, but it hurt when I wiped again, so I thought it might be due to wiping too hard and causing a small tear.
I do not have abdominal pain or fever, and aside from occasionally feeling a slight burning sensation in my stomach, everything else seems normal.
I do not have hemorrhoids.
What could be causing this? If the same situation does not occur in a few days, is it necessary to see a doctor? Will it heal on its own? Thank you.

More Info

Seeing blood in your stool can be alarming, especially if it’s a new occurrence for you. There are several potential causes for this symptom, and understanding them can help you determine whether you need to seek medical attention.

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 veins in the lower rectum or anus. They can bleed during bowel movements, especially if you are straining or if the stool is hard. Given that you mentioned experiencing some blood when wiping, this could be a likely cause.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can cause sharp pain and bleeding during bowel movements. If you’ve been wiping too hard, this could also lead to a fissure.

3. Gastrointestinal Issues: Conditions like diverticulosis, inflammatory bowel disease (IBD), or infections can also lead to blood in the stool. These conditions may present with other symptoms, such as abdominal pain or changes in bowel habits.

4. Dietary Factors: You mentioned consuming spicy foods like 麻辣滷味 (spicy braised dishes) regularly. While these foods may not directly cause blood in the stool, they can irritate the gastrointestinal tract, especially if consumed in excess.

5. Other Medical Conditions: Less commonly, blood in the stool can indicate more serious conditions such as polyps or colorectal cancer, especially if you have a family history of such diseases.

When to Seek Medical Help
Given your situation, here are some guidelines on when to seek medical attention:
- Persistent Symptoms: If you continue to see blood in your stool over the next few days, it’s important to consult a healthcare professional. Even if the bleeding is minor, persistent symptoms warrant evaluation.

- Associated Symptoms: If you develop additional symptoms such as abdominal pain, fever, significant changes in bowel habits, or if the blood becomes more significant, you should seek medical attention immediately.

- Family History: If there is a family history of gastrointestinal diseases, it’s advisable to discuss your symptoms with a doctor sooner rather than later.

Self-Care and Management
In the meantime, here are some self-care tips:
- Dietary Adjustments: Consider moderating your intake of spicy and potentially irritating foods. Increasing fiber in your diet can help soften stools and reduce straining during bowel movements.

- Hydration: Ensure you are drinking plenty of water, which can help prevent constipation and make bowel movements easier.

- Gentle Wiping: Be gentle when wiping after a bowel movement to avoid further irritation or injury to the anal area.

Conclusion
While it’s possible that the blood you observed could be due to minor issues like hemorrhoids or anal fissures, it’s crucial to monitor your symptoms closely. If the bleeding continues or if you experience any concerning symptoms, don’t hesitate to reach out to a healthcare provider. They can perform a thorough evaluation and provide appropriate treatment if necessary. Remember, it’s always better to err on the side of caution when it comes to your health.
