Prospective monitoring In daily practice, I often ask my patients with B12 deficiency to maintain a sheet with their most prominent symptoms
B12 can only be absorbed in the presence of IF
When to seek medical care Adults should seek medical care if they have unexplained fatigue, weakness, shortness of breath, dizziness, numbness or tingling in the hands or feet, balance problems, memory changes, or a sore tongue
For a subcutaneous B12 injection, a finer, shorter needle is used: around 25 to 27 gauge and half to five-eighths of an inch
