Red stool in the toilet?


Hello, doctor.
Today when I used the restroom, my stool turned the toilet red.
The appearance of the stool was normal golden yellow, but one piece was broken and inside it was purplish-red.
When I moved it slightly, it changed the color of the entire toilet.
I used toilet paper to dab the red stool, and it didn't stain red, which made me really scared.
Could this be intestinal bleeding?

More Info


When you notice red stool in the toilet, it can understandably cause concern, as it may indicate gastrointestinal bleeding. However, it's important to assess the situation carefully before jumping to conclusions. Based on the information provided, the stool appears to be primarily golden yellow, with a segment that is purple-red. This detail is crucial, as the color and consistency of stool can provide insights into potential underlying issues.

First, let's discuss the possible causes of red stool. Red or reddish stool can arise from several factors, including dietary choices, medications, and medical conditions. Foods that are red or contain red dyes, such as beets, tomatoes, or certain candies, can lead to a temporary change in stool color. If you have consumed any of these foods recently, it could explain the red coloration. Additionally, certain medications, particularly those containing iron or bismuth (like Pepto-Bismol), can also alter stool color.

However, if the red color is not attributable to food or medication, it may indicate bleeding somewhere in the gastrointestinal tract. The location of the bleeding can often be inferred from the color of the stool. Bright red blood typically suggests bleeding from the lower gastrointestinal tract, such as the rectum or colon, while darker blood may indicate bleeding from higher up in the digestive system, such as the stomach or small intestine.

In your case, the presence of a purple-red segment within otherwise normal stool raises a few possibilities. It could be a sign of bleeding, particularly if the red color is not linked to dietary factors. The fact that the red stool did not stain the toilet paper when dabbed may suggest that the blood is mixed within the stool rather than being fresh blood from the rectum. This could indicate a more complex issue, such as hemorrhoids, anal fissures, or even polyps or tumors in the colon.

Given the potential seriousness of gastrointestinal bleeding, it is essential to seek medical attention if you experience any of the following symptoms:
1. Persistent red or black stool.

2. Abdominal pain or cramping.

3. Dizziness or lightheadedness, which could indicate significant blood loss.

4. Changes in bowel habits, such as diarrhea or constipation, that last more than a few days.

A healthcare professional will likely recommend a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly diagnostic tests such as a stool test or a colonoscopy. These tests can help determine the source of the bleeding and guide appropriate treatment.

In summary, while red stool can be alarming, it is not always indicative of a severe problem. Dietary factors and medications can play a significant role in stool color. However, if there is any doubt or if you experience additional concerning symptoms, it is crucial to consult with a healthcare provider for a comprehensive evaluation. Early diagnosis and treatment can significantly improve outcomes and address any underlying health issues effectively.
