Therefore, it is important to maintain adequate Vitamin B12 levels to avoid permanent neurological affects
If you have a B12 deficiency, thats likely the cause for your anemia in the first place
For patients seeking weight loss who request B12 injections, GPs should: Assess for genuine deficiency through appropriate blood tests rather than empirical treatment Provide education about the lack of evidence supporting B12 for weight loss in non-deficient individuals Explore underlying concerns about weight and energy levels, addressing these through appropriate channels Signpost to evidence-based resources such as NHS weight management services according to local pathways Patients should contact their GP if they experience unexplained fatigue, neurological symptoms (numbness, tingling, balance problems), or signs of anaemia (pallor, breathlessness, palpitations), as these may indicate B12 deficiency requiring investigation
The AAFP advises that injectable therapy leads to more rapid improvement and should be considered in patients with severe deficiency or severe neurologic symptoms (Langan RC, Goodbred AJ, 2017)
