Q: Blood in Stool: Definitions and Concerns for Patients

Bowel issues

Hello, doctor: I would like to ask you a question.
What is the definition of "hematochezia"? If the stool color is normal (yellow), and after defecating, I observe a slight deep yellow discoloration spreading at the bottom of the toilet after 10-15 minutes, or a slightly dark color, I am unsure if this counts as being reddish.
Does this qualify as hematochezia?
My second question is about the presence of light yellow mucus with an unpleasant odor when wiping after using the bathroom, which occurs at irregular intervals.
Is this normal or indicative of an abnormal condition? I recently underwent a digital rectal examination, and the doctor indicated that there were no abnormalities, even after performing a thorough examination twice.
Should I consider undergoing further tests? Thank you for your attention.

More Info

Understanding blood in stool is crucial for patients, as it can be indicative of various underlying health issues. "Blood in stool," or hematochezia, refers to the presence of red or dark red blood in the stool, which can be alarming for patients. The definition of blood in stool is quite specific: it typically refers to visible blood that can be seen in the stool or on toilet paper after a bowel movement. This blood can vary in color, from bright red to dark maroon, depending on where in the gastrointestinal tract the bleeding is occurring.

In your case, you mentioned observing a slight deep yellow discoloration in the toilet water after a bowel movement, which may not necessarily indicate blood. If the stool itself is yellow and there is only a faint discoloration in the water, it is less likely to be blood. However, if you notice any bright red streaks on the stool or toilet paper, or if the stool appears darker than usual, it is advisable to seek medical attention. The presence of blood in stool can be caused by various conditions, including hemorrhoids, anal fissures, diverticulosis, inflammatory bowel disease (IBD), or even colorectal cancer, so it is essential to monitor any changes closely.

Regarding your second question about the presence of a yellowish mucus with an unpleasant odor when wiping, this could be related to several factors. Mucus in the stool can be normal, as it helps to lubricate the intestines. However, if it is accompanied by a foul smell or occurs frequently, it may indicate an underlying issue, such as an infection, inflammatory bowel disease, or a gastrointestinal disorder. The intermittent nature of the mucus can also suggest that it is related to dietary factors or stress.

Since you have already undergone a digital rectal examination and the doctor found no abnormalities, it may be worth considering further investigations if your symptoms persist or worsen. Additional tests could include a colonoscopy, stool tests, or imaging studies to rule out any significant gastrointestinal issues. It is essential to communicate openly with your healthcare provider about your symptoms and any concerns you may have, as they can guide you on the appropriate next steps.

In summary, while the presence of blood in stool can be concerning, it is essential to consider the context and other symptoms. If you are uncertain about your observations or if your symptoms persist, do not hesitate to seek further medical evaluation. Early detection and intervention can significantly improve outcomes for many gastrointestinal conditions.
