Blood in the stool with blood clots?


Hello, doctor.
Today I noticed bright red blood and blood clots in my stool, and there was also some in the toilet.
My stool appeared black...
I'm not sure if it was because I ate something too spicy the day before, which made my stomach feel strange at night, and I also felt a burning sensation in my anus during bowel movements.
However, this morning my stool did not have any blood.
It was only in the afternoon that I discovered the blood and blood clots, and by evening, I had experienced this symptom twice, along with some mild pain in my lower right abdomen.
Recently, I've seen online that bloody stools can be a symptom of colon cancer, and I'm really worried that I might have such warning signs.
I usually have bowel movements about three times a day and don't experience much constipation.
I love fried foods and don't like to exercise.
Could being a frequent diner be related to this? Could you please provide me with some answers, or if I need to see a doctor, which specialty would be the most appropriate? Thank you.

Blood in the stool, along with changes in gastrointestinal function and bowel habits, is an abnormal symptom.
Possible diagnoses range from hemorrhoids to other serious gastrointestinal diseases.
It is recommended to visit a hospital's gastroenterology or surgical outpatient department for further examination and treatment.

Hello! It sounds like you are experiencing some concerning symptoms, and it's understandable to feel anxious about them. Let's break down the situation regarding blood in your stool, its potential causes, and when you should seek medical attention.


Understanding Blood in Stool
Seeing blood in your stool can be alarming, and it's important to understand that there are various potential causes. The presence of bright red blood typically indicates that the bleeding is occurring in the lower gastrointestinal tract, such as the rectum or anus. In contrast, dark or black stools (often described as "tarry") can suggest bleeding from higher up in the gastrointestinal tract, such as the stomach or small intestine.


Possible Causes
1. Hemorrhoids: One of the most common causes of bright red blood in the stool is hemorrhoids, which are swollen veins in the rectal area. They can cause pain, itching, and bleeding, especially during bowel movements.

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 and bleeding during bowel movements.

3. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the intestines, leading to blood in the stool.

4. Diverticular Disease: Diverticulosis and diverticulitis can cause bleeding, especially in older adults.

5. Polyps or Colorectal Cancer: While less common, polyps (growths on the colon lining) can bleed, and in some cases, they can be precursors to colorectal cancer. Given your concerns about colorectal cancer, it's essential to consider this possibility, especially if you have risk factors such as a family history or lifestyle factors like a diet high in processed foods and low in fiber.


Symptoms to Monitor
You mentioned experiencing some abdominal pain, particularly in the right lower quadrant. This could be related to several issues, including those mentioned above. It's important to monitor for additional symptoms such as:
- Persistent abdominal pain
- Changes in bowel habits (e.g., diarrhea or constipation)
- Unexplained weight loss
- Fatigue or weakness
- Fever

When to Seek Help
Given that you have observed blood in your stool multiple times and are experiencing abdominal pain, it is advisable to seek medical attention. You should consider visiting a healthcare provider as soon as possible. Here are some guidelines on when to seek help:
- If you experience significant or persistent bleeding.

- If you have severe abdominal pain.

- If you notice changes in your bowel habits that last more than a few days.

- If you experience other concerning symptoms such as weight loss or fatigue.


Which Specialist to See
For your symptoms, you should consider seeing a gastroenterologist, a specialist in digestive system disorders. They can perform the necessary evaluations, which may include a physical examination, blood tests, and possibly imaging studies or a colonoscopy to determine the cause of the bleeding.


Conclusion
In summary, while there are many potential causes for blood in the stool, it is crucial to take these symptoms seriously, especially given your concerns about colorectal cancer. Lifestyle factors, such as diet and exercise, can play a significant role in gastrointestinal health, so consider making changes to improve your overall well-being. Please do not hesitate to seek medical attention to get a proper diagnosis and treatment. Your health is important, and addressing these symptoms promptly can lead to better outcomes.
