Hello, my aunt is 45 years old and recently her stool has a color similar to white fungus.
What could this be related to? If she wants to see a doctor, should she consult a hepatobiliary and gastroenterology specialist?

Hello, if you have grayish-white stools, it is generally suspected to be related to recent dietary influences or issues with the bile ducts.
If the stools are white and semi-transparent with mucus, it may be due to indigestion.
If these symptoms persist for a longer duration, such as more than 1 to 2 weeks, it is advisable to seek medical attention from a gastroenterologist.
Wishing you good health.
Sincerely, Dr.

More Info

When it comes to unusual stool colors, it’s essential to understand that stool can vary significantly based on a variety of factors, including diet, medications, and underlying health conditions. In your aunt's case, the stool resembling the color of white fungus (or "白木耳") could indicate several potential issues that warrant further investigation.

Stool color can be influenced by the foods we eat. For instance, a diet high in dairy products, certain medications, or supplements can lead to lighter-colored stools. However, if the stool is consistently pale or clay-colored, it could suggest a problem with bile production or flow, which is crucial for proper digestion and gives stool its typical brown color. Bile is produced by the liver and stored in the gallbladder, and any obstruction in the bile ducts or liver issues can lead to changes in stool color.

Given your aunt's age and the change in her stool color, it would be prudent for her to consult a gastroenterologist. A gastroenterologist specializes in the digestive system and can perform the necessary evaluations to determine the underlying cause of the color change. This may include blood tests to assess liver function, imaging studies such as an ultrasound or CT scan to check for any blockages or abnormalities in the liver or bile ducts, and possibly a stool test to rule out infections or malabsorption issues.

In addition to color changes, other symptoms should also be taken into account. If your aunt experiences any accompanying symptoms such as abdominal pain, jaundice (yellowing of the skin or eyes), dark urine, or unexplained weight loss, these could be signs of a more serious condition that requires immediate medical attention.

It’s also worth noting that while some variations in stool color can be benign and related to dietary choices, persistent changes, especially those that deviate significantly from the normal brown color, should not be ignored. The liver and gallbladder play critical roles in digestion, and any dysfunction in these organs can lead to significant health issues.

In summary, if your aunt is noticing a consistent change in her stool color to a pale or clay-like appearance, it is advisable for her to see a gastroenterologist. Early evaluation and diagnosis can lead to appropriate management and treatment, ensuring that any potential issues are addressed promptly.
