Abstract
Background:
Methods
intramuscular injections hydroxocobalamin, 1000 μg.
The mean age was 45.3 ± 12.4 years, with a female predominance (60%), at baseline,
the mean RBC count was 3.1 ± 0.5 × 10^12/L, which rose significantly to 3.8 ± 0.4 × 10^12/L
at 6 weeks and 4.5 ± 0.3 × 10^12/L by 12 weeks (p<0.001). Hemoglobin levels increasing from
9.2 ± 1.8 g/dL to 11.5 ± 1.2 g/dL at 6 weeks and 13.0 ± 1.0 g/dL at 12 weeks (p<0.001).Mean
corpuscular volume (MCV) of 110.2 ± 6.8 fL at baseline, normalized to 101.6 ± 5.9 fL at 6
weeks and 95.4 ± 5.3 fL by 12 weeks (p<0.001).
Conclusion: Vitamin B12 supplementation is a corner stone in managing anemia due to B12
deficiency. Prompt diagnosis and treatment significantly improve RBC count, hemoglobin
levels, and patient-reported outcomes.
