定义
单独缺乏维生素B6不常见，它通常与其他B族维生素缺乏有关。维生素B6缺乏症常与核黄素（维生素B2）缺乏症一起发生。维生素B6缺乏症的典型临床症状是脂溢性皮炎、小细胞性贫血、癫痫性抽搐、抑郁症和精神错乱。婴儿特别容易摄入不足，这可能导致癫痫性抽搐。此外，通常会出现循环淋巴细胞减少，有时也会出现正常细胞性、小细胞性或铁粒幼细胞贫血。与其他微量营养素缺乏症一样，维生素B6缺乏症会导致免疫系统受损。一些医疗情况也可影响维生素B6代谢，从而导致缺乏症状。
A deficiency of vitamin B6 alone is uncommon because it usually occurs in association with a deficit in other B-complex vitamins. Hypovitaminosis B6 may often occur with riboflavin (vitamin B2) deficiency. The classical clinical symptoms of vitamin B6 deficiency are a seborrheic dermatitis, microcytic anaemia, epileptiform convulsions, and depression and confusion. Infants are especially susceptible to insufficient intakes, which can lead to epileptiform convulsions. Moreover, there is usually a decrease in circulating lymphocytes and sometimes a normocytic, microcytic, or sideroblastic anaemia as well. As is the case with other micronutrient deficiencies, vitamin B6 deficiency results in an impairment of the immune system. Several medical conditions can also affect vitamin B6 metabolism and thus lead to deficiency symptoms.
