耳聋常由先天或遗传、年老、外伤、药物中毒、噪音及急性传染病引起,但缺钙引起耳聋还是近年来的新发现。英国科学家证实,缺钙可致耳蜗局限性脱钙,继而耳蜗形态改变破坏内耳听觉上皮细胞或骨结构,产生耳聋、耳鸣。在探讨缺钙本质时还发现缺钙的真实原因在于钙代谢紊乱及体内维D含量不足或缺乏。维D缺乏可有五大原因:一是皮肤在日光下暴露不足,阳光照射不够;二是饮食 Deafness often caused by congenital or genetic, elderly, trauma, drug poisoning, noise and acute infectious diseases, but calcium deficiency caused by deafness or new discoveries in recent years. British scientists confirmed that calcium deficiency can cause limited cochlear decalcification, followed by changes in cochlear morphology damage to the inner ear auditory epithelial cells or bone structure, resulting in deafness, tinnitus. In exploring the nature of calcium deficiency also found that the real cause of calcium deficiency is calcium disorders and vitamin D deficiency in vivo content or lack of. Victoria D deficiency can have five major reasons: First, the skin exposed to insufficient sunlight, insufficient sun exposure; the second is diet
