Diabetes mellitus (DM) is a major and growing concern in the United States, in large part because of an epidemic of obesity in America and its relation to type 2 DM. In affected patients, postprandial glucose may be an early indicator of glucose intolerance or a prediabetes condition, which may be a better predictor of cardiovascular risk than impaired fasting glucose level. Treating patients who have early signs of hyperglycemia, including elevated postprandial glucose level, with intensive glucose control that does not lead to weight gain, and ideally may be associated with weight reduction, may be vital to preventing or reducing later cardiovascular morbidity and mortality. Because hypoglycemia is an important complication of current DM treatments and may cause acute secondary adverse cardiovascular outcomes, not causing hypoglycemia is mandatory. Given that weight loss can significantly lower cardiovascular risk and improve other cardiovascular risk factors in patients with type 2 DM and that medications are available that can result in weight reduction without leading to hypoglycemia, the successful treatment of patients with type 2 DM should be individualized and should address the complete pathophysiologic process. This review is a hypothesis article that presents arguments against general approaches to the treatment of type 2 DM. An algorithm is presented in which the goal for managing patients with type 2 DM is to lower the blood glucose level as much as possible for as long as possible without causing hypoglycemia. In addition, body weight should ideally be improved, reducing cardiovascular risk factors and avoiding therapeutic inertia.
糖尿病(DM)在美国是一个主要且日益严重的问题,主要是因为美国肥胖症的流行及其与 2 型 DM 的关系。在受影响的患者中,餐后血糖可能是葡萄糖耐量异常或糖尿病前期的早期指标,其可能比空腹血糖水平受损更能预测心血管风险。通过强化血糖控制来治疗有高血糖早期迹象的患者,包括升高的餐后血糖水平,这种控制不会导致体重增加,理想情况下还可能与体重减轻相关,对于预防或减少后期心血管发病率和死亡率可能至关重要。由于低血糖是当前 DM 治疗的重要并发症,并且可能导致急性继发性不良心血管结局,因此必须避免低血糖。鉴于体重减轻可以显著降低 2 型 DM 患者的心血管风险并改善其他心血管风险因素,并且存在可以导致体重减轻而不会导致低血糖的药物,因此 2 型 DM 患者的成功治疗应该个体化,并应针对完整的病理生理过程。这是一篇假设性文章,提出了反对 2 型 DM 治疗一般方法的论点。提出了一种算法,其中管理 2 型 DM 患者的目标是在不引起低血糖的情况下尽可能长时间地尽可能降低血糖水平。此外,理想情况下应改善体重,降低心血管风险因素并避免治疗惰性。
