Understanding Variations in Bilirubin Levels: Is It Cause for Alarm?
Hello everyone, I’m a 27-year-old male and recently underwent a comprehensive health screening. Upon examining my results, I noticed some variations in my bilirubin levels, which caught my attention. Generally, the accepted upper limit for total bilirubin is approximately 1.3 mg/dL; however, my readings have occasionally exceeded this range. Here are my test results for your reference: **December (Non-fasting):** Total Bilirubin: 0.95 mg/dL (within normal limits) **March 15 (Fasting ~20 hours, strict low-carb diet):** Total Bilirubin: 1.79 mg/dL (elevated) Direct: 0.6 mg/dL Indirect: 1.19 mg/dL **March 30 Afternoon (Fasting ~11 hours):** Total Bilirubin: 1.35 mg/dL (slightly elevated) Direct: 0.4 mg/dL Indirect: 0.95 mg/dL **March 30 Evening (Fasting ~15 hours):** Total Bilirubin: 1.57 mg/dL (elevated) Direct: 0.3 mg/dL Indirect: 1.27 mg/dL **Additional Considerations:** - My daily water intake is about 1.5 liters—could this be a factor in dehydration? - Liver enzyme levels (ALT, AST, ALP, GGT) are within the normal range. - I followed extended fasting before a few of these tests. - I adhered to a very low-carb diet leading up to my March 15 assessment. **Questions I Have:** - Might dehydration or prolonged fasting be influencing these variations in bilirubin? - Given that my liver enzymes are normal, should I truly worry about these fluctuations? - Is it possible that I have Gilbert's Syndrome? As a side note, my physician regarded the readings below 2.0 mg/dL as acceptable, yet I am curious to hear insights from others who might have experienced similar variations in bilirubin. Thank you!

Your variations in bilirubin levels can be concerning, but contextual factors matter significantly. Based on your test results and considering your normal liver enzyme levels, there may be explanations for these fluctuations that are not necessarily alarming.
Overview
- Bilirubin levels can fluctuate due to various factors, including dehydration, dietary choices, and metabolic changes related to fasting.
- Gilbert's syndrome, a common and often benign condition, can also cause elevated indirect bilirubin levels without associated liver dysfunction.
Explanation
Bilirubin is a substance produced during the breakdown of red blood cells. It is processed by the liver, and normal variations in levels can be influenced by several factors.
-
Dehydration: Your water intake is at 1.5 liters, which may not be sufficient for everyone, particularly if you're active or if the weather is hot. Dehydration can concentrate various substances in the blood, potentially raising bilirubin levels.
-
Fasting and Diet: Extended fasting, especially if combined with a low-carb diet, may put stress on your liver and alter bilirubin metabolism temporarily.
-
Gilbert's Syndrome: This genetic condition is characterized by intermittent elevations in bilirubin, particularly the indirect form. It typically doesn't cause any health issues and is recognized as a benign condition.
Next Steps
Here are some prioritized steps to consider:
-
Increase Hydration: Aim for at least 2-3 liters of water daily, especially if you are fasting or following restrictive diets. This can help your kidneys and liver process waste more effectively.
-
Follow-Up Testing: Consider monitoring your bilirubin levels again in a few weeks after ensuring adequate hydration and a balanced diet. This can help identify if levels stabilize or continue to fluctuate.
-
Maintain a Balanced Diet: Try to adopt a more balanced eating plan, including a variety of nutrients to support liver health while avoiding extreme fasting or dietary restrictions.
-
Document Symptoms: Keep a record of any symptoms (like fatigue or jaundice) you might experience, as well as any other dietary habits or lifestyle changes to assess potential correlations with bilirubin levels.
-
Discuss Concerns with a Physician: Although your physician has assured you that levels below 2.0 mg/dL are acceptable, keeping them informed about your concerns can help them assess if further investigation (like testing for Gilbert's syndrome) is warranted.
By following these steps, you can better address your concerns about bilirubin levels and support your overall health. Let me know if you have further questions!

Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.

Intense Pain in Left Thumb
Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.
