What causes B12 deficiency in older adults?
Older adults are particularly at risk of vitamin B12 deficiency because of the high prevalence of atrophic gastritis-associated food-cobalamin (vitamin B12) malabsorption, and the increasing prevalence of pernicious anaemia with advancing age. Not only this, certain medications can also result in B12 malabsorption and result in deficiency.
