Stool color


Hello Dr.
Chen, this morning during a bowel movement, I noticed that one end of the stool had a white color, approximately 0.5 in size, while the rest of the stool was of normal color.
After wiping with toilet paper, I noticed some slightly transparent white mucus on the paper.
I visited a doctor yesterday for a sore throat and was prescribed the following medications: A Luton tab (extra-strength acetaminophen), Corey 100mg SR, Depyretin 500mg tab, Ibuprofen 400mg, Prednisolone 5mg, and Weisufu tablets.
For breakfast yesterday, I had a milkshake, and for lunch and dinner, I ate a bento box that included vegetables, bitter melon, braised pork, tofu skin, and cabbage.
I don't think the bento box is the issue.
Could this be related to the medications?

It's just the normal secretion of mucus from the colon; there's no need to worry.

More Info


When it comes to abnormal stool colors, there are several factors to consider, including dietary choices, medications, and underlying health conditions. In your case, you mentioned observing a white coloration at one end of your stool, along with some transparent white mucus on the toilet paper after wiping. Let's break down the potential causes and concerns associated with these observations.


Dietary Influences
The foods you consume can significantly affect the color and consistency of your stool. For instance, certain foods can lead to changes in stool color. In your case, you mentioned eating a variety of foods, including vegetables like bitter melon and cabbage, which typically do not cause significant color changes. However, if you consumed any foods with artificial coloring or certain natural pigments, these could potentially alter the color of your stool.


Medications
You listed several medications you are currently taking, including Luton (a combination of acetaminophen and caffeine), Corey (a type of antihistamine), Depyretin (an anti-inflammatory), Ibuprofen (another anti-inflammatory), and Prednisolone (a corticosteroid). Some medications can cause gastrointestinal side effects, including changes in stool color or consistency. For example, medications containing iron can lead to dark stools, while certain antibiotics can cause lighter-colored stools or diarrhea. The presence of mucus could also be a side effect of the medications, as they can irritate the gastrointestinal tract.


Mucus in Stool
The presence of mucus in your stool can be a normal occurrence, as the intestines produce mucus to help lubricate the stool and facilitate its passage. However, if you notice an increase in the amount of mucus or if it is accompanied by other symptoms such as abdominal pain, diarrhea, or blood in the stool, it could indicate an underlying issue such as an infection, inflammatory bowel disease (IBD), or irritable bowel syndrome (IBS).


White Stool
The appearance of white or pale stools can be concerning, as it may indicate a lack of bile, which is produced by the liver and is responsible for the brown color of normal stool. Conditions affecting the liver, gallbladder, or bile ducts can lead to pale stools. However, in your case, since the white coloration is localized to one end of the stool and you have not reported any other concerning symptoms (such as jaundice, severe abdominal pain, or significant changes in appetite), it may not be a cause for alarm.


Recommendations
1. Monitor Symptoms: Keep an eye on your stool color and consistency over the next few days. If the white coloration persists or if you notice any additional symptoms (such as pain, fever, or changes in appetite), it would be wise to consult a healthcare professional.

2. Hydration and Diet: Ensure you are staying well-hydrated and consuming a balanced diet. If you suspect that any specific food or medication is causing the changes, consider discussing this with your doctor.

3. Follow-Up with Your Doctor: Given that you are currently on several medications, it might be beneficial to follow up with your healthcare provider. They can assess whether your medications could be contributing to your symptoms and may suggest alternatives if necessary.

4. Seek Immediate Care if Necessary: If you experience severe symptoms such as significant abdominal pain, persistent diarrhea, or blood in your stool, seek medical attention promptly.

In conclusion, while changes in stool color can be concerning, they are often related to dietary choices or medications. Monitoring your symptoms and consulting with a healthcare professional if necessary will help ensure that any potential issues are addressed appropriately.
