Rectal bleeding can be a concerning symptom, and it’s important to understand the potential causes and when to seek medical attention. Based on your description, it seems you experienced some abdominal discomfort, followed by episodes of diarrhea that included blood in your stool. Here’s a detailed explanation of possible causes, when to see a doctor, and what you should keep in mind.


Possible Causes of Rectal Bleeding
1. Hemorrhoids: One of the most common causes of rectal bleeding, hemorrhoids are swollen veins in the lower rectum or anus. They can cause bright red blood during bowel movements, especially if you are straining due to constipation or diarrhea.

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

3. Gastrointestinal Infections: Infections caused by bacteria, viruses, or parasites can lead to diarrhea that may contain blood. This is often accompanied by other symptoms such as fever, abdominal pain, and nausea.

4. Diverticulosis: This condition involves the formation of small pouches in the colon wall, which can become inflamed or infected, leading to diverticulitis. This can cause bleeding and abdominal pain.

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

6. Polyps or Colorectal Cancer: Although less common, polyps in the colon can bleed, and they may be precursors to colorectal cancer. If you are experiencing rectal bleeding, especially if it is persistent, it is important to rule out these serious conditions.


When to See a Doctor
You should seek medical attention if you experience any of the following:
- Persistent Bleeding: If the bleeding continues or worsens, it is crucial to consult a healthcare provider.

- Severe Abdominal Pain: If you experience significant pain that does not improve, it may indicate a more serious condition.

- Changes in Bowel Habits: If you notice a change in your bowel habits, such as prolonged diarrhea or constipation, it’s important to get evaluated.

- Signs of Anemia: Symptoms such as fatigue, weakness, or dizziness could indicate significant blood loss and warrant immediate medical attention.

- Accompanying Symptoms: If you have fever, chills, or unexplained weight loss, these could be signs of a more serious underlying condition.


Recommendations
- Hydration: Ensure you stay hydrated, especially if you have diarrhea. Drink plenty of fluids to replace lost fluids.

- Dietary Adjustments: Consider a bland diet to help your digestive system recover. Avoid spicy, fatty, or heavy foods that may exacerbate your symptoms.

- Monitor Symptoms: Keep track of your symptoms, including the frequency and amount of blood, as well as any changes in your bowel habits.

- Consult a Doctor: Given your symptoms, it would be wise to consult a healthcare provider. They may recommend tests such as a stool analysis, colonoscopy, or imaging studies to determine the cause of your bleeding.


Conclusion
While rectal bleeding can be caused by a variety of conditions, some of which are benign, it is essential to take it seriously, especially if it persists or is accompanied by other concerning symptoms. Early diagnosis and treatment can help prevent complications and ensure better health outcomes. If you have any doubts or if your symptoms worsen, do not hesitate to seek medical attention. Your health is paramount, and a healthcare professional can provide the best guidance tailored to your specific situation.
