Blood in Stool: Causes and When to Seek Help

Blood in the stool?

Last month, I experienced severe constipation for a week, not having a bowel movement for three days.
After going to an all-you-can-eat restaurant, I finally felt the urge to go, but it was very painful, especially when the stool was passing.
There was fresh blood on the stool and on the toilet paper, but after wiping a second time, there was none.
For the next few days, bowel movements were quite painful, and I noticed blood again.
I increased my water intake, which improved my condition, and my stool became golden yellow.
However, last week I experienced some constipation again, with hard, pellet-like stools.
The next day, I had another painful bowel movement with blood.
I continued to increase my water intake, and it got better.
On March 18, I only drank about 500 c.c.
of fluids.
There was no blood on the surface of the stool, but fresh blood flowed from the side of the toilet; it was a small amount.
The stool had both golden yellow and darker colors, with a significant difference in texture between the two.
Could this be colon cancer? I tend to eat fewer vegetables.

Based on your description, it seems to be an anal fissure.
The typical symptoms include pain during bowel movements accompanied by slight bleeding.
The primary cause of anal fissures is usually hard stools; however, diarrhea, frequent bowel movements, or prolonged straining can also lead to fissures.
It is recommended to improve bowel habits and take warm sitz baths to alleviate symptoms.
Topical ointments and suppositories can also be used for treatment.
Although the likelihood of developing colorectal cancer at the age of 16 is not zero, it is generally very low.
It is advisable to maintain a light diet and a good lifestyle.
If symptoms persist without improvement, you may consult a physician for medication.

More Info

Blood in stool can be a concerning symptom, and it’s important to understand its potential causes and when to seek medical help. Based on your description, it seems that you have experienced a few episodes of blood in your stool, particularly after periods of constipation, which can lead to anal fissures or hemorrhoids. These conditions are common and can cause pain and bleeding, especially when passing hard stools.

Possible Causes of Blood in Stool
1. Hemorrhoids: Swollen blood vessels in the rectal area can bleed, especially during bowel movements. This is often associated with straining, which can occur during constipation.

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

3. Diverticular Disease: Diverticulosis can lead to diverticulitis, which may cause bleeding. This is more common in older adults.

4. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract.

5. Polyps or Colorectal Cancer: While less common, polyps can bleed, and colorectal cancer can present with blood in the stool, especially if accompanied by changes in bowel habits or weight loss.

When to Seek Medical Help
You should seek medical attention if you experience any of the following:
- Persistent Blood: If you notice blood in your stool consistently over several days.

- Large Amounts of Blood: If you see a significant amount of blood or if it is accompanied by clots.

- Changes in Bowel Habits: If you experience a change in your bowel habits, such as diarrhea or constipation that lasts more than a few days.

- Pain: Severe abdominal pain, cramping, or discomfort that does not improve.

- Other Symptoms: Symptoms such as weight loss, fatigue, or changes in appetite.

Recommendations
1. Increase Fiber Intake: Since you mentioned eating less vegetables, increasing your fiber intake can help soften your stools and prevent constipation. Foods high in fiber include fruits, vegetables, whole grains, and legumes.

2. Stay Hydrated: Drinking plenty of fluids is essential for maintaining healthy bowel movements. Aim for at least 8 glasses of water a day, especially if you are increasing your fiber intake.

3. Monitor Symptoms: Keep track of when you see blood, how much, and any associated symptoms. This information can be helpful for your healthcare provider.

4. Consult a Healthcare Provider: Given your concerns about colorectal cancer, it would be prudent to consult a healthcare provider. They may recommend a physical examination, blood tests, or imaging studies, and possibly a colonoscopy to rule out any serious conditions.

Conclusion
While your symptoms may be due to common issues like hemorrhoids or anal fissures, it is essential to take blood in stool seriously. Your history of constipation and the presence of blood suggest that there may be an underlying issue that needs to be addressed. A healthcare professional can provide a thorough evaluation and guide you on the appropriate next steps. Remember, early detection and intervention are key to managing any potential health issues effectively.
