Blood in the stool?


Hello doctor, when I go to the bathroom (which takes about 10 minutes), I noticed that the water at the bottom of the toilet was red when I wiped myself at the end.
The red color was completely settled at the bottom, while the rest of the water was not red.
The color of the toilet paper and my stool was normal, and I haven't eaten any red foods in the past two days (except for some spicy chicken wings yesterday).
Could this be blood? Can it settle at the bottom like that? This isn't the first time it has happened; I've experienced it before.
I always check my stool, and sometimes right after I finish, I look and see that it appears brick red (this is what I saw in the past; today I didn't check immediately).
However, when I go to wipe, it appears normal, and then the water at the bottom turns completely red.
Could this be caused by food?

When you notice blood in your stool or changes in the color of your bowel movements, it can understandably be a cause for concern. Based on your description, it seems that you have experienced red discoloration in the toilet water after a bowel movement, with the stool itself appearing normal. This situation raises several important considerations regarding potential causes and what steps you should take next.

Firstly, the presence of red in the toilet water can indeed indicate the presence of blood. However, the fact that your stool appears normal and that the red color is primarily in the water could suggest that the blood is coming from the lower part of the gastrointestinal tract, such as the rectum or anus, rather than from higher up in the digestive system. This is often referred to as "hematochezia," which is the passage of fresh blood through the anus, typically indicating bleeding from the lower gastrointestinal tract.

There are several potential causes for this type of bleeding:
1. Hemorrhoids: Swollen blood vessels in the rectal area can cause bright red blood to appear in the toilet or on toilet paper. This is one of the most common causes of blood in the stool, especially if you experience discomfort or itching.

2. Anal Fissures: Small tears in the lining of the anus can occur, often due to passing hard stools. This can lead to bleeding and pain during bowel movements.

3. Diverticular Disease: Diverticula are small pouches that can form in the walls of the colon. If these become inflamed or infected, they can bleed.

4. Colorectal Polyps or Cancer: While less common, polyps or cancer in the colon can also cause bleeding. This is particularly a concern if you have a family history of colorectal cancer or if you are over the age of 50.

5. Gastrointestinal Infections: Certain infections can lead to inflammation and bleeding in the intestines.

Given that you have experienced this issue multiple times, it is crucial to consult with a healthcare professional for a thorough evaluation. They may recommend a physical examination, a digital rectal exam, or even more advanced imaging studies such as a colonoscopy to visualize the colon and rectum directly. This will help determine the exact cause of the bleeding.

In the meantime, it is important to monitor your symptoms closely. Take note of any additional signs such as changes in bowel habits, abdominal pain, weight loss, or changes in appetite, as these can provide valuable information to your healthcare provider.

Regarding your concern about whether the red color could be due to food, it is possible for certain foods to cause temporary changes in stool color. However, since you mentioned that you have not consumed any red foods recently, it is less likely that this is the primary cause. Spicy foods, like the chicken wings you mentioned, can sometimes irritate the gastrointestinal tract but are not typically associated with blood in the stool.

In summary, while the presence of red in the toilet water can be alarming, it is essential to approach this situation with a clear understanding of potential causes. Seeking medical advice is the best course of action to ensure proper diagnosis and treatment. Early intervention can be crucial, especially if there are underlying conditions that need to be addressed. Please do not hesitate to reach out to a healthcare provider to discuss your symptoms and get the appropriate care.
