Blood in Stool: Possible Causes and Symptoms

Blood in the stool?

Hello, doctor.
For the past three weeks, I have been having bowel movements almost every morning and evening, with frequent flatulence.
This week has improved somewhat; over the past few days, I haven't felt significant pain during bowel movements.
The color of my stool is yellow-brown with a slight amount of bright red blood on top, approximately the size of a coin less than one dollar.
When I wipe my bottom with toilet paper, there are slight streaks of blood that are sticky.
What could be causing these symptoms?

Based on your description, it seems more like irritable bowel syndrome combined with mild hemorrhoidal bleeding.
It is recommended to start with a light diet and maintain a good daily routine.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you may consult a physician for medication.
If there is still no improvement or if you are very concerned, a colonoscopy can be arranged.

More Info

When it comes to blood in stool, it’s essential to understand that this symptom can arise from various underlying causes, some of which may require immediate medical attention. The presence of bright red blood in your stool or on toilet paper can indicate bleeding in the lower gastrointestinal tract, such as the rectum or anus, while darker blood may suggest bleeding higher up in the digestive system.

Based on your description, the fact that you have experienced frequent bowel movements and gas, along with the presence of bright red blood, could suggest several potential causes:
1. Hemorrhoids: One of the most common causes of bright red blood in stool is hemorrhoids, which are swollen veins in the lower rectum or anus. They can cause bleeding, especially during bowel movements, and may be accompanied by discomfort or itching.

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

3. Diverticular Disease: Diverticulosis occurs when small pouches form in the walls of the colon. If these pouches become inflamed or infected (diverticulitis), they can cause bleeding.

4. Colorectal Polyps or Cancer: While less common, the presence of blood in the stool can also be a sign of polyps or colorectal cancer, especially if accompanied by other symptoms such as changes in bowel habits, weight loss, or abdominal pain.

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

Given your symptoms, it is crucial to seek medical evaluation. A healthcare provider may recommend several diagnostic tests, including:
- Physical Examination: A thorough examination, including a digital rectal exam, can help identify hemorrhoids or fissures.

- Colonoscopy: This procedure allows the doctor to view the inside of your colon and rectum, helping to identify any abnormalities such as polyps or tumors.

- Stool Tests: These can help identify infections or blood in the stool that may not be visible.

- Blood Tests: To check for anemia or other underlying conditions.

In the meantime, it’s important to maintain a healthy diet rich in fiber to help prevent constipation, which can exacerbate hemorrhoids and fissures. Staying hydrated and avoiding straining during bowel movements can also be beneficial.

In conclusion, while the presence of blood in your stool can be alarming, it is essential to approach the situation calmly and seek medical advice. Early diagnosis and treatment can significantly improve outcomes, especially if there are underlying conditions that need to be addressed. Please consult a healthcare professional as soon as possible to discuss your symptoms and receive appropriate care.
