vitamin B12 deficiency is not caused by a lack of vitamin B12 in your diet, youll usually need to have an injection of hydroxocobalamin every 2 to 3 months
A patient in perimenopause will not get the same duration as a twenty-eight-year-old on the same protocol, and that is normal physiology, not a failure of treatment
GPs can prescribe B12 injections following appropriate investigation, which should include: Full blood count to identify macrocytic anaemia Serum B12 and folate levels to confirm deficiency (using laboratory-specific reference ranges) Methylmalonic acid and/or homocysteine when B12 results are borderline Intrinsic factor antibodies if pernicious anaemia is suspected Additional tests depending on clinical presentation (e.g., thyroid function, coeliac serology) When both B12 and folate deficiency are present, B12 should be replaced before folate to avoid precipitating subacute combined degeneration of the spinal cord
Your doctor may suggest injections or nasal gels for Vitamin B12 deficiency in pregnancy
Homocysteine and folate as risk factors for dementia and Alzheimer disease
The schedule depends on your lab results and cause of deficiency
