Dark Red Blood in Stool: Causes and Concerns - Surgery

Rectal bleeding


Hello, doctor.
Recently, I've been experiencing blood in my stool, which is dark red.
Often, after I have a bowel movement, the toilet is filled with red, and there is a significant amount of blood on the toilet paper, enough to soak through it.
However, I do not feel any pain or burning sensation.
My bowel movements have increased in frequency but decreased in volume.
I've had similar situations in the past, but they usually resolved within 2 to 3 days.
This time, the condition has persisted for almost a week, and I'm unsure what the issue might be.

Hello, if you are experiencing rectal bleeding, it is important to first determine whether the bleeding is from the upper or lower gastrointestinal tract.
Upper gastrointestinal bleeding requires an esophagogastroduodenoscopy (EGD), while lower gastrointestinal bleeding necessitates a colonoscopy.
Of course, hemorrhoidal bleeding or perianal bleeding are the most likely causes, but gastrointestinal diseases must be ruled out first.

When it comes to the presence of dark red blood in stool, it is essential to understand the potential causes and the necessary steps to address the situation. The symptoms you describe—dark red blood in your stool, significant blood on toilet paper, and changes in bowel habits—can be concerning and warrant further investigation.


Possible Causes
1. Hemorrhoids: One of the most common causes of bright red blood in the stool or on toilet paper is hemorrhoids. These are swollen veins in the lower rectum or anus that can bleed during bowel movements, especially if there is straining or constipation involved. The blood is typically bright red and may be seen on the toilet paper or in the toilet bowl.

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, and the blood is usually bright red.

3. Diverticular Disease: Diverticulosis can lead to diverticulitis, which is the inflammation of diverticula in the colon. This condition can cause bleeding, which may present as dark red blood in the stool.

4. Colorectal Polyps or Cancer: While less common, the presence of blood in the stool can be a sign of colorectal polyps or cancer. These conditions may not always present with pain, and changes in bowel habits, such as increased frequency or altered stool consistency, can be indicative.

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

6. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause chronic inflammation of the gastrointestinal tract, leading to symptoms such as blood in the stool, abdominal pain, and changes in bowel habits.


Recommendations for Management
Given that you have been experiencing these symptoms for nearly a week, it is crucial to seek medical attention. Here are some steps you should consider:
1. Consult a Healthcare Provider: Schedule an appointment with a gastroenterologist or your primary care physician. They may recommend a physical examination, blood tests, and possibly imaging studies or a colonoscopy to determine the underlying cause of the bleeding.

2. Keep a Symptom Diary: Document your bowel habits, the appearance of your stool, any associated symptoms (such as pain, changes in appetite, or weight loss), and any dietary changes. This information can be valuable for your healthcare provider.

3. Avoid Straining: If hemorrhoids or anal fissures are suspected, try to avoid straining during bowel movements. Increasing dietary fiber and hydration can help soften stools and reduce the risk of further bleeding.

4. Monitor for Additional Symptoms: Be vigilant for any new symptoms, such as significant abdominal pain, fever, or changes in your overall health. If you experience these, seek immediate medical attention.

5. Dietary Adjustments: While waiting for your appointment, consider avoiding spicy foods, alcohol, and caffeine, which can irritate the gastrointestinal tract.


Conclusion
While the presence of dark red blood in your stool can be alarming, it is essential to approach the situation calmly and seek appropriate medical evaluation. Early diagnosis and treatment can significantly improve outcomes, especially if there are underlying conditions that need to be addressed. Remember, your health is paramount, and timely intervention can make a significant difference.
