I have been experiencing occasional dizziness over the past few days. To investigate, I underwent a blood test, and my results showed:
Hemoglobin (HB): 18 g/dL
Vitamin B12: 187 pg/mL (low)
Cholesterol: [As shown in the attached image]
I do not smoke or drink. I am a bit concerned about my high hemoglobin levels. Could you please share your insights on whether this is something to worry about and any further tests or lifestyle changes I should consider?
