Patient's Query

Hello doctor,

Throughout my adult life, I have had persistent stomach issues like diarrhea, cramps, and more. Approximately six months ago, I received a diagnosis of celiac disease and also had slightly elevated liver enzymes. Since then, I have been adhering to a strict gluten-free diet without cross-contamination. This has improved the consistency and regularity of my stools. My test results have shown positive changes in the indicators related to gluten exposure.

But, there are a couple of issues I have been unable to resolve. Firstly, my stools continue to appear green, varying in shade from brighter to darker green. Secondly, I have been experiencing tenderness and inflammation on my right side, radiating from my back to the front, situated just below the rib cage. Some medical professionals have suggested it might be a muscular issue, but I do not believe that anymore. These symptoms have persisted for nearly a year, and the side pain goes back about five years, recurring periodically during that time. I have not experienced any weight loss, nausea, or vomiting. Five years ago, when the pain initially began, I underwent a stomach ultrasound that did not reveal any significant findings.

After researching online, I am concerned that there may be an issue with my bile ducts or gallbladder. I will not be able to see my gastroenterologist for another month, and even then, there might be additional waiting time for further examinations like an endoscopy or similar tests to investigate the area. I am seeking some clarity on what might be causing the green stools as I await my doctor's appointment. If it seems urgent, I would appreciate your advice on whether I should bring this up with my primary care physician sooner. Please clarify.

Thank you.

Hello,

Welcome to icliniq.com.

I have thoroughly reviewed your case history, and I would like to provide a step-by-step analysis:

  1. Your altered bowel habits, including diarrhea and cramps, align with the diagnosis of celiac disease, especially given the improvement you have experienced since adopting a gluten-free diet.
  2. The mildly abnormal liver function tests (LFTs) can also be attributed to celiac disease. But, these should have improved by now, given the management of your celiac condition.
  3. If your LFTs remain abnormal, we should consider other potential causes, such as alcohol-related issues, fatty liver, or common infections like hepatitis B or C.
  4. The right-sided pain near the ribcage is of particular concern since it corresponds to the location of the liver. An enlarged liver, often caused by conditions like fatty liver or alcohol-related concerns, could lead to prolonged dull pain. The accuracy of ultrasound results can vary depending on the operator, potentially leading to underreporting of mild liver conditions.
  5. Another possibility is gallbladder-related pain, but this can be detected easily on ultrasound, making it less likely if the previous ultrasound was reported as normal.
  6. Prolonged periods of sitting or the use of computers can lead to costochondritis, inflammation of the lowermost rib border, causing persistent pain, particularly at the same location. This is often associated with truncal obesity.
  7. Regarding green stools, the issue can be addressed by conducting a microscopic examination of a stool sample, known as a stool detailed report. Dietary factors like the consumption of leafy vegetables or bacterial overgrowth in the gut, can also lead to changes in stool color.
  8. Alarming stool colors to watch out for include fresh red blood, maroon stools (indicating altered blood), or deep black stools (indicative of upper gastrointestinal bleeding).

To investigate your condition further, I would suggest you do comprehensive liver function tests, a high-quality abdominal ultrasound, and stool examination, as mentioned earlier, to pinpoint the cause of your green stools. In the meantime, pay attention to your diet to identify any potential sources of green stools. I would also suggest you add probiotics like yogurt to your diet daily. Continue observing your stool color for the next 1-2 weeks.

Thank you.

Patient's Query

Hello doctor,

Thank you for replying.

I have shared some of my recent testing results. These results include a comprehensive blood workup, including platelet count, hemoglobin levels, and thyroid function, all of which returned within the normal range. I have undergone a fecal test, and I am curious to know if the results from this test could provide an explanation for the persistently green stools or if I should request a different panel of tests. I incorporate kale into my morning smoothies and consume leafy vegetables and I am uncertain whether this dietary factor alone could account for the green color of my stools over an extended period.

Regarding my liver function, I have an upcoming test scheduled for next week, as my doctor recommended a follow-up to assess the previously reported results which I have attached. I hope that these levels have improved now that my celiac condition is under control. In a few weeks, I intend to raise these questions with my gastroenterologist, to identify the root causes behind the persistent dull pain and unusual stool color. I truly appreciate your prompt assistance in this matter.

Thank you.

Hello,

Welcome back to icliniq.com.

Thank you for your response.

After carefully reviewing your reports (attachments removed to protect the patient's identity), some key points I would like to highlight are:

  1. It is reassuring that your recent blood workup, which includes a complete blood profile and thyroid evaluation, returned within the normal range.
  2. Your mentioned investigation reports, particularly the Hepatitis C and stool tests, have also come back with normal results, which is a positive sign.
  3. The negative result for the fecal occult blood test is encouraging, as this test is effective in detecting even trace amounts of blood in stools and is often used as an indicator for decisions like colonoscopy. In your case, it is a good sign.
  4. The negative or normal result of the fecal calprotectin test, which is highly sensitive to gut inflammation, is also reassuring. This test is typically used to differentiate between irritable bowel syndrome and inflammatory bowel issues. Your result indicates that significant inflammation within the colon is unlikely.

I would suggest you to recheck your liver function tests and undergo another ultrasound to confirm the normal condition of your liver, gallbladder, and biliary channels.

In the meantime, consider reducing your consumption of green leafy vegetables, including kale, and monitor any changes in stool color. If you have no dietary restrictions, adding meat to your diet may be a worthwhile consideration. Continuing to include yogurt and commercially available probiotics in your diet is beneficial, as this can aid in restoring the balance of your natural gut microbiota.

Thank you.

Kind regards
