The first medical description of pernicious anaemia is from 1821. It is written by Dr James Combe and describes a previously well 47 year old corn-merchant who presented with pallor, weakness, and neurological symptoms. It would take over a hundred years before we would know how to treat this condition, and another decade after that to understand why the treatment worked.
Vitamin B12 is an essential component of our diet and only found in animal products. Deficiency in vitamin B12 can present with fatigue, anaemia (macrocytic), and neurological symptoms. The most at risk from a dietary perspective are vegetarians, vegans, and the elderly. Patients may also have an autoimmune condition (pernicious anaemia) that interferes with gastric parietal cells and intrinsic factor; the way our body can absorb vitamin B12 from our diet.
This is the story of vitamin B12.
