Understanding blood in stool can be a concerning issue, and it’s important to approach it with a clear understanding of potential causes, implications, and necessary next steps. Based on your description, it seems you have experienced a few episodes of rectal bleeding, which can be alarming. Let's break down the possible causes, what they might mean, and what you should consider doing next.


Possible Causes of Blood in Stool
1. Hemorrhoids: As your mother suggested, hemorrhoids are a common cause of blood in the stool, especially if the blood is bright red and appears on the surface of the stool or on toilet paper. They can be caused by straining during bowel movements, which can occur with constipation.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can cause sharp pain during and after bowel movements, along with bright red blood.

3. Diverticular Disease: This condition involves the formation of small pouches in the colon wall, which can become inflamed or infected, leading to bleeding.

4. Polyps or Colorectal Cancer: While less common, especially in younger individuals, polyps can bleed and may be precursors to colorectal cancer. Given your age, this is less likely, but it’s still a possibility that should be ruled out.

5. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract, leading to blood in the stool.

6. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause significant gastrointestinal symptoms, including bleeding.


Concerns and Symptoms to Monitor
- Pain: You mentioned experiencing pain during bowel movements, which could indicate an anal fissure or hemorrhoids. However, persistent or severe abdominal pain should be evaluated.


- Weight Loss: A sudden weight loss of 3 kg, especially if unintentional, is concerning and should be discussed with a healthcare provider. Weight loss can be a sign of underlying health issues, including malignancies.

- Changes in Bowel Habits: Any significant changes in bowel habits, such as increased frequency, diarrhea, or constipation, should be noted.

- Fever: If you experience fever alongside gastrointestinal symptoms, it could indicate an infection or inflammation that requires prompt medical attention.


Next Steps
1. Consult a Healthcare Provider: Given the symptoms you’ve described, it is crucial to consult with a healthcare provider as soon as possible. They may recommend a physical examination and possibly a referral for a colonoscopy to visualize the colon and identify any abnormalities.

2. Prepare for a Colonoscopy: Since you are already preparing for a colonoscopy, ensure you follow the preparation instructions carefully. This procedure will help diagnose the cause of the bleeding and assess for any polyps or other issues.

3. Diet and Lifestyle: While you are eating more vegetables and walking regularly, which are positive changes, ensure you are also staying hydrated and managing stress, as stress can exacerbate gastrointestinal issues.

4. Monitor Symptoms: Keep a detailed record of your symptoms, including when the blood appears, any associated pain, changes in bowel habits, and any other symptoms like fever or weight loss. This information will be valuable for your healthcare provider.


Conclusion
Blood in the stool is a symptom that should not be ignored, and while it can often be attributed to benign causes like hemorrhoids or fissures, it is essential to rule out more serious conditions. Given your recent experiences, including weight loss and changes in appetite, it is advisable to seek medical evaluation promptly. Early diagnosis and treatment can significantly improve outcomes and provide peace of mind.
