据Updegraff 1979年报告,最常见和最易忽略的引起眩晕的原因是碳水化合物与胰岛素代谢紊乱。他用5年的时间评价了575例眩晕患者,发现至少有90%的患者有代谢障碍问题,有75%的患者其代谢障碍是引发眩晕的唯一原因。本文报告了50例不明原因的顽固性的间断发作的眩晕患者,其中真性眩晕36例,非典型头晕14例,平均年龄42岁(19～70岁),女性20例,男性30例,全部患者近期无感染、创伤或药物中毒史。临床检查包括电测听、神经学检查、全血常规、性病诊断法检查、游离甲状腺激素测定(FTI)等均正常,唯电眼震图均不正常。同时,对全部患者进行了代谢检查,包括五小时糖耐量试验和测定胰岛素水平,结果发现90%(45例) According to Updegraff’s 1979 report, the most common and easily overlooked cause of dizziness is carbohydrate and insulin metabolism disorders. He evaluated 575 patients with vertigo for five years and found that at least 90% of patients had metabolic disorders and 75% of them had the only metabolic disorder that was the only cause of dizziness. This article reports 50 patients with unexplained intractable intermittent episodes of vertigo, including 36 cases of vertigo of vertigo, 14 cases of atypical dizziness, mean age of 42 years (19 to 70 years), 20 females and 30 males, all patients No recent infection, trauma or drug poisoning history. Clinical examination including electrical audiometry, neurological examination, whole blood routine, STD examination, free thyroid hormone test (FTI) are normal, the only electronystagmography are not normal. At the same time, all patients were metabolized, including five hours of glucose tolerance test and determination of insulin levels, and found that 90% (45 cases)
