定义
核黄素缺乏症的症状是咽喉痛、充血、咽部和口腔粘膜水肿、唇干裂、口角炎、舌炎、脂溢性皮炎和与骨髓纯红细胞增多有关的正色素性贫血。低核黄素血症的主要原因是由于食物供应有限而导致的饮食摄入不足，有时由于食物储存或加工不当而加剧。在胃肠道感染流行的年份，发展中国家的儿童通常会表现出核黄素缺乏的临床症状。消化异常也会导致核黄素同化减少，例如乳糖不耐症。
The signs of riboflavin deficiency are sore throat, hyperaemia, oedema of the pharyngeal and oral mucous membranes, cheilosis, angular stomatitis, glossitis, seborrheic dermatitis, and normochromic normocytic anaemia associated with pure red cell cytoplasia of the bone marrow. The major cause of hyporiboflavinosis is inadequate dietary intake as a result of limited food supply, which is sometimes exacerbated by poor food storage or processing. Children in developing countries will commonly demonstrate clinical signs of riboflavin deficiency during periods of the year when gastrointestinal infections are prevalent. Decreased assimilation of riboflavin also results from abnormal digestion, such as that which occurs with lactose intolerance.
