Blood-Streaked Mucus in Stool: Causes and Concerns - Surgery

Thick, mucous fluid with streaks of blood in the stool?


Hello doctor, over the past couple of days, I have noticed that my stool is accompanied by a viscous liquid mixed with streaks of blood.
I do not have diarrhea or constipation, and there is no blood found on the toilet paper after wiping.
My anus is not painful.
Sometimes my stool is golden yellow and other times it is darker in color.
Upon closer inspection, the stool appears to be formed in strands.
I tend to eat spicy food, which often leads to diarrhea.
Recently, I had an external hemorrhoid that improved with medication.
In the past few days, I noticed a polyp-like growth coming out of my anus after using the bathroom, but it is no longer present.
The appearance of the blood in my stool resembles what I found online about colorectal cancer, which makes me a bit worried, but I have no other health issues.

Dr. Ke Fangxu reply Surgery


At the age of 25, the likelihood of developing colorectal cancer is not zero, but generally speaking, it is very, very low.
Based on your description, it seems more like it could be caused by intestinal inflammation.
It is advisable to start with a light diet and maintain a good lifestyle.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you may consult a physician for medication or consider undergoing a colonoscopy.

Blood-streaked mucus in stool can be concerning, and it's understandable that you're worried, especially given your history of hemorrhoids and dietary habits. Let's break down the potential causes and what you should consider.

Firstly, the presence of blood in your stool, even if it's just streaks, can be indicative of several conditions. The fact that you mentioned seeing mucus mixed with blood suggests that there may be some irritation or inflammation in your gastrointestinal tract. Here are some common causes:
1. Hemorrhoids: Since you have a history of external hemorrhoids, it's possible that they could be causing the blood streaks. Hemorrhoids can bleed, especially after straining during bowel movements, and this bleeding can sometimes be mixed with mucus.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to bleeding and discomfort, but you mentioned that you don't have pain, which makes this less likely.

3. Gastrointestinal Infections: Infections can cause inflammation in the intestines, leading to mucus and blood in the stool. This is often accompanied by diarrhea, but not always.

4. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause symptoms such as blood and mucus in the stool. These conditions often present with other symptoms like abdominal pain, diarrhea, and weight loss.

5. Polyps or Colorectal Cancer: While you mentioned that you're concerned about colorectal cancer, it's important to note that cancer typically presents with other symptoms, such as significant changes in bowel habits, unexplained weight loss, or persistent abdominal pain. However, the presence of blood in the stool, especially if it's accompanied by changes in stool appearance (like the black color you mentioned), should not be ignored.

6. Dietary Factors: Your love for spicy food can sometimes lead to gastrointestinal irritation, which might manifest as mucus in the stool. However, it’s less likely to cause blood unless there is an underlying condition.

Given your symptoms, it is crucial to consult a healthcare professional for a thorough evaluation. They may recommend a physical examination, a stool test, or even a colonoscopy to rule out any serious conditions, especially considering your concerns about colorectal cancer.
In the meantime, keep track of any additional symptoms you may experience, such as changes in appetite, weight loss, or any new abdominal pain. This information will be valuable for your healthcare provider.

Lastly, while it's easy to get caught up in online research, it's important to remember that self-diagnosis can lead to unnecessary anxiety. A healthcare professional can provide a proper diagnosis and treatment plan tailored to your specific situation. Don't hesitate to seek medical advice, as early intervention can make a significant difference in outcomes for many gastrointestinal conditions.
