Grayish-White Stool: Potential Liver and Digestive Issues

Stool that is pale gray or white in color?

Hello Doctor: Since last year, my bowel movements have become unusual.
Previously, there was only a small corner of my stool that appeared gray, and I didn't pay much attention to it.
However, today I noticed that half of my stool is a deep grayish-white color and loose.
I immediately searched online and found that some people suggested it could be jaundice or liver and gallbladder issues, and even mentioned the possibility of pancreatic cancer or bile duct cancer! But my sclera is still very white and does not appear jaundiced...
Later, after reading some articles about black stools, I became concerned that it might just be lighter-colored black stools...
Doctor, what do you think is happening to me? P.S.
I currently have favism, fatty liver (which was discovered during an ultrasound), a history of asthma, and I experience left upper abdominal pain after eating, frequent central left back soreness, and intermittent pain in the upper right abdomen.
I also have a burning sensation in my stomach around lunchtime.
My current habits include occasionally taking B vitamins, gastrointestinal health supplements, and asthma chewable tablets.
I have a habit of staying up late and sitting for long periods.
An unusual observation is that I have lost about two kilograms (approximately 2.3% of my original weight) in about a month.

Further observation is recommended.
If symptoms persist or if there is weight loss, medical evaluation should be sought.

More Info

Grayish-white stool can be a concerning symptom, as it may indicate underlying liver or digestive issues. The color of stool is primarily influenced by bile, which is produced by the liver and stored in the gallbladder. Bile is responsible for the typical brown color of stool. When there is a disruption in bile production or flow, the stool can appear lighter or grayish-white.

In your case, the presence of grayish-white stool, especially if it is accompanied by other symptoms such as abdominal pain, could suggest several potential issues. One possibility is a blockage in the bile ducts, which can occur due to gallstones, strictures, or tumors. This blockage can prevent bile from reaching the intestines, leading to lighter-colored stool. Conditions such as pancreatitis or pancreatic cancer can also cause similar symptoms, as they may affect bile production and flow.

It's important to note that while you mentioned not having jaundice (yellowing of the skin or eyes), the absence of this symptom does not rule out liver or biliary issues. Jaundice occurs when there is an excess of bilirubin in the blood, often due to liver dysfunction or bile duct obstruction. The fact that your eyes are clear does provide some reassurance, but it does not eliminate the need for further investigation.

Given your medical history of fatty liver disease and symptoms such as left upper abdominal pain and burning sensations, it is crucial to seek medical attention. These symptoms, combined with the change in stool color, warrant a thorough evaluation by a healthcare professional. Tests such as liver function tests, imaging studies like an abdominal ultrasound or CT scan, and possibly endoscopic procedures may be necessary to determine the underlying cause of your symptoms.

Additionally, your mention of having favism (a condition related to a deficiency in the enzyme glucose-6-phosphate dehydrogenase) and asthma may complicate your overall health picture. It is essential to manage these conditions effectively while addressing your gastrointestinal symptoms.

In summary, grayish-white stool can indicate significant liver or digestive issues, and it is advisable to consult with a healthcare provider for a comprehensive evaluation. Early diagnosis and treatment are crucial in managing any potential liver or biliary conditions, especially given your existing health concerns. Please do not delay in seeking medical advice, as timely intervention can lead to better outcomes.
