Long-Term Fatty Stools: Causes and When to Seek Help

Chronic fatty stools

Hello Doctor, in the past few months, I have noticed a layer of clear, colorless oil floating on the surface of my stool during bowel movements.
The amount varies, and it usually disappears on its own after about 4-5 days, only to reappear after some time.
The oil is more noticeable when I have softer stools.
A gastroenterologist suggested that it might be related to dietary issues and advised me to monitor my urine for any tea-colored appearance or jaundice, but no tests were conducted.
My observations showed no abnormalities, and I have not experienced any other unusual symptoms, although I occasionally have diarrhea.
The issue of fatty stools continues to occur despite my efforts to completely avoid high-fat foods; I primarily eat a vegetarian diet with occasional meat.
Two years ago, I underwent surgery for colon cancer (at the rectosigmoid junction), and since then, my gastrointestinal motility has increased, resulting in visible undigested food in my stool.
I am wondering if the fatty stools could be related to this.
Should I consider going back to the hospital to request further examinations? Thank you for your response, Dr.
Chen.

Check liver function, biliary enzymes, and pancreatic enzymes.
If any abnormalities are found, further evaluation with abdominal ultrasound or even computed tomography (CT) scan may be necessary.
If all tests are normal, dietary adjustments should be made, and digestive enzymes may be prescribed if needed.

More Info

Fatty stools, also known as steatorrhea, can be a concerning symptom that indicates an underlying issue with fat absorption in the digestive system. The presence of oil or a greasy layer on the surface of your stool suggests that your body may not be effectively absorbing fats from the foods you consume. This can occur due to various reasons, including pancreatic insufficiency, liver disease, or issues with the intestines themselves.

Given your history of colon surgery, particularly near the junction of the rectum and colon, it is possible that your digestive system's ability to process fats has been affected. Surgery in this area can alter the normal function of the intestines, leading to changes in bowel habits and nutrient absorption. The fact that you are experiencing fatty stools intermittently, along with occasional diarrhea, further supports the need for a thorough evaluation.

While dietary changes, such as reducing high-fat foods and focusing on a vegetarian diet, can help manage symptoms, they may not address the underlying cause of your steatorrhea. It is essential to consider that even with a healthy diet, if your body is not able to absorb nutrients properly, you may still experience these symptoms.

You mentioned that your gastroenterologist suggested that dietary issues might be the primary cause and advised you to monitor for signs of jaundice or dark urine. While these are important indicators, they do not rule out the possibility of other conditions that could be affecting your digestion. Since you have not reported any other alarming symptoms, it is a positive sign, but it does not eliminate the need for further investigation.

In terms of seeking help, it would be prudent to return to your healthcare provider and express your ongoing concerns about the fatty stools. You should request a more comprehensive evaluation, which may include tests such as stool analysis, blood tests to check liver function, and possibly imaging studies to assess the pancreas and intestines. These tests can help identify whether there is a specific condition affecting your ability to digest fats properly.

Additionally, you may want to consider consulting a registered dietitian who specializes in gastrointestinal health. They can help you develop a tailored eating plan that meets your nutritional needs while considering your digestive issues. They may also provide insights into how to manage your symptoms through diet more effectively.

In summary, while dietary modifications are a good first step, they may not be sufficient if there is an underlying medical condition affecting your digestion. It is essential to communicate your symptoms clearly to your healthcare provider and advocate for further testing to determine the root cause of your fatty stools. Early intervention can lead to better management of your symptoms and overall health.
