Elevated Red Blood Cell Count and Hematocrit Considerations
I’m a 64-year-old male, standing at 5'10" and weighing 165 pounds. My current medications include amlodipine and atorvastatin. Thankfully, both my blood pressure and cholesterol levels are within acceptable limits. I maintain good physical fitness and feel quite well overall. I don’t use tobacco, drink socially, and have a mild marijuana use. Additionally, for context, I have Ashkenazi Jewish heritage. Recently, my lab results showed an increase in my red blood cell (RBC) count to 5.84, compared to 5.77 18 months ago. Hematocrit levels also rose slightly to 52.4 from 52.3 during the same period. It appears that both values have increased over the last five years. In my research, I came across the term polycythemia vera, which is concerning when exploring the reasons behind my elevated RBC count. I also have a family history of non-Hodgkin lymphoma from my father. I understand that further testing is necessary to determine the cause, but I can’t help but feel anxious about the long wait this weekend. Are there any benign reasons that could account for these higher readings? The 5.84 RBC count is outside the reference range provided by my lab, though it seems to fall below the 6.1 reference level at other laboratories. I genuinely hope there are alternative explanations for these results. By the way, I appreciate any insights you can offer!

Your concern regarding elevated levels of red blood cells and hematocrit is understandable, especially given your research into polycythemia vera. While it’s important to consider serious conditions, there are also benign explanations for your elevated results.
Key Points:
- Elevated RBC count and hematocrit can be caused by various factors, some of which are not serious.
- Conditions like dehydration, living at high altitudes, or even smoking (which you don’t do) can contribute to higher RBC levels.
- Your physical fitness could also be a factor, as regular exercise sometimes leads to higher red blood cell production.
Explanation: Red blood cells are responsible for carrying oxygen throughout your body, and an increased count can arise from several benign conditions. For instance:
- Dehydration: Less fluid in your bloodstream can concentrate your blood cells, raising their levels.
- Living at High Altitude: If you live at a higher elevation, your body compensates by producing more red blood cells to ensure adequate oxygen delivery.
- Chronic Hypoxia: Any condition that affects oxygen delivery to your tissues might cause your body to increase red blood cell production.
- Physical Fitness: Endurance athletes often show elevated RBC counts due to the physiological adaptations to increased oxygen demands.
Next Steps:
- Hydration Check: Ensure you’re adequately hydrated. Drink plenty of fluids throughout the day.
- Monitor for Symptoms: Keep an eye out for symptoms like headaches, dizziness, or excessive fatigue that might suggest your condition is affecting you.
- Record Changes: Write down any new symptoms or changes you notice over the next few days, which can be helpful for your healthcare provider.
- Stay Informed: Understand that elevated counts can sometimes be temporary or due to benign factors. Avoid excessive worry until further testing clarifies the situation.
If your RBC count continues to rise or if you develop concerning symptoms, you will need to follow up with your healthcare provider for further evaluation, likely including tests like a complete blood count and possibly testing for specific conditions.

My Relationship with Milk Consumption
For nearly two decades, I have predominantly relied on milk as my primary source of hydration, consuming around five liters daily. Although I recognize that this reliance might not be the healthiest choice, my low appetite has perpetually left me underweight. In the past, I attempted to transition to drinking water; however, I noticed a concerning drop in weight along with persistent fatigue. My inquiry is whether there exists a more nutritious method to obtain calories without resorting to solid foods, and ideally, without incurring high costs?
When Can I Expect to Drive Again?
I’m a 35-year-old who suffered a spiral fracture in my right leg affecting both the fibula and tibia.

Given this progress, what is a realistic timeframe for when I might be able to drive safely once more?
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.
