Understanding High B12 and Calcium Levels in Blood Tests
A 28-year-old woman, who is a smoker and measures 159 cm in height with a weight of 67 kg, is currently living with a diagnosis of polycystic ovary syndrome (PCOS) and idiopathic intracranial hypertension. Additionally, she has been identified with moderate fatty liver and is prescribed Diamox at a dosage of 250 mg, taken once daily. Following a recent blood test, she found elevated levels of vitamin B12 and calcium. This individual had taken a multivitamin that included biotin approximately 15 hours prior to the blood draw. The question arises: what might be responsible for the increased levels of B12 and calcium?

Increased levels of vitamin B12 and calcium in your blood can arise from various factors, especially considering your medical history and recent multivitamin use. Let's break down the potential reasons:
Main Points
-
Vitamin B12 Elevation:
- High B12 levels are often not a cause for concern, especially if you have been supplementing. Over-supplementation or recent intake from food or supplements can elevate levels temporarily.
-
Calcium Elevation:
- High calcium levels can be related to several conditions, including hyperparathyroidism, certain medications, or increased intake from supplements or diet.
Explanation
-
Vitamin B12: It's water-soluble, and if excess B12 is consumed (from supplements or diet), it can accumulate in the blood. In your case, the multivitamin taken 15 hours before the test may have contributed to the elevated levels. Elevated B12 alone typically isn't harmful and may not indicate a serious health issue.
-
Calcium: Elevated calcium levels can indicate issues with parathyroid hormone levels or kidney function, but they can also result from dietary or supplemental intake. If you weren’t intentionally increasing your calcium intake, it might be worth investigating further.
Next Steps
-
Monitor Symptoms:
- Keep an eye on any symptoms such as fatigue, confusion, increased thirst, or frequent urination, as these could help clarify any underlying issues.
-
Review Supplement Intake:
- Consider reviewing the dosage of the multivitamin and any other supplements, especially those containing calcium or B12. If necessary, adjust your intake according to product guidelines or dietary needs.
-
Recheck Levels:
- Plan to have your blood levels rechecked in a few weeks to see if they normalize, especially if you modify your supplement use.
-
Healthy Lifestyle Choices:
- Focus on a balanced diet, reducing smoking, and maintaining a healthy weight to support your overall health, particularly given your PCOS and fatty liver condition.
-
Keep a Detailed Record:
- Document any supplements taken, dietary intake, and symptoms in a journal to share with a healthcare provider if further investigation is needed.
By taking these steps, you can better understand and manage your elevated B12 and calcium levels. If you have further concerns or any unusual symptoms arise, consider discussing them with a healthcare professional for a tailored evaluation.

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.
Unexplained Bruises on My Right Hand – Seeking Advice
I've noticed some unusual bruising on my right hand over the past month. Strangely enough, they don't hurt at all. Should I be concerned about this? It's quite puzzling to see these random marks without any apparent cause.
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.
Persistent Need to Stretch Legs While Seated
I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.
