Rectal bleeding


Hello doctor, I have recently noticed small specks of light red blood in my stool.
Yesterday, my stool was pellet-like, but only one pellet had light red blood.
I've been experiencing a dull pain in my upper mid-abdomen.
I had an endoscopy that showed mild gastroesophageal reflux and mild gastritis.
I often feel movement in my intestines.
What could be wrong with me?

Rectal bleeding is considered an abnormal symptom and can range from common conditions like hemorrhoids to more serious gastrointestinal diseases.
Based on your description, hemorrhoidal bleeding is the most likely cause.
However, you also mentioned other symptoms such as difficulty in bowel movements and constipation.
It is recommended that you visit a hospital's surgical or gastroenterology department for further evaluation.

More Info


When it comes to the presence of blood in stool, it can be concerning and warrants careful evaluation. The symptoms you describe, including the presence of faint red blood in your stool and upper abdominal discomfort, can have various underlying causes. Here’s a comprehensive overview of potential causes, when to seek medical help, and what steps you might consider taking.


Potential 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 cause bleeding during bowel movements, often accompanied by discomfort or itching.

2. Anal Fissures: These are small tears in the lining of the anus, usually caused by passing hard stools. They can lead to sharp pain during bowel movements and may also result in bright red blood.

3. Gastrointestinal Bleeding: Conditions such as diverticulosis, polyps, or colorectal cancer can cause bleeding in the gastrointestinal tract. The blood may appear dark or maroon if it originates from higher up in the digestive system.

4. Gastritis or Ulcers: Given your history of gastroesophageal reflux disease (GERD) and mild gastritis, it’s possible that inflammation or ulcers in the stomach or upper gastrointestinal tract could be contributing to your symptoms. While these conditions typically cause dark, tarry stools if bleeding occurs, they can sometimes present with bright red blood if the bleeding is more acute.

5. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can lead to inflammation of the intestines, resulting in blood in the stool, abdominal pain, and changes in bowel habits.

6. Infections: Certain infections, particularly those affecting the gastrointestinal tract, can lead to bloody diarrhea. These infections can be caused by bacteria, viruses, or parasites.


When to Seek Medical Help
You should seek medical attention if you experience any of the following:
- Persistent or Worsening Symptoms: If the blood in your stool continues or worsens, it’s important to consult a healthcare provider.

- Severe Abdominal Pain: If you experience significant or worsening abdominal pain, this could indicate a more serious condition.

- Changes in Bowel Habits: If you notice changes in your bowel habits, such as diarrhea or constipation, along with blood in the stool.

- Signs of Anemia: Symptoms such as fatigue, weakness, or shortness of breath could indicate significant blood loss and should be evaluated promptly.

- Fever or Chills: These could suggest an infection that requires treatment.


Next Steps
1. Consult a Gastroenterologist: Given your symptoms and history, it would be prudent to see a gastroenterologist. They may recommend further diagnostic tests, such as a colonoscopy, to evaluate the source of the bleeding.

2. Keep a Symptom Diary: Documenting your symptoms, including the frequency of blood in your stool, any associated pain, and dietary habits, can provide valuable information for your healthcare provider.

3. Dietary Considerations: While waiting for your appointment, consider maintaining a balanced diet rich in fiber to help with bowel regularity. Avoiding irritants such as spicy foods, caffeine, and alcohol may also help alleviate some gastrointestinal discomfort.

4. Follow-Up on GERD Treatment: Since you have a history of GERD and gastritis, ensure that you are following up with your primary care physician or gastroenterologist regarding the management of these conditions.

In summary, while the presence of blood in your stool can be alarming, many causes are treatable. It’s essential to seek medical evaluation to determine the underlying cause and appropriate treatment. Your health is paramount, and addressing these symptoms early can lead to better outcomes.
