Abstract. Vegetarianism and veganism are very popular, and although these diets may be associated with certain health benefits, the low bioavailability of some micronutrients in plant foods can lead to the risk of their deficiency in the body, which makes it necessary to adequately plan such diets. Vitamin B12 is absorbed by humans exclusively from food of animal origin; therefore, vegans as well as anyone who significantly limits the consumption of animal products need vitamin complexes enriched with vitamin B12. This article discusses a clinical case of severe nutritional B12 deficiency anemia in a young patient at risk (a vegan) with rare hemorrhagic manifestation as hyposphagma (subconjunctival hemorrhage).
Keywords: young woman, veganism, B12 deficiency anemia, subconjunctival hemorrhage, hyposphagma
