Diabetes mellitus (DM) is a chronic condition with several subtypes that differ in etiology and clinical progression. Type 2 diabetes (T2DM) is the most commonly diagnosed form and is closely linked to obesity and physical inactivity, while type 1 diabetes (T1DM) is largely autoimmune in origin. A less understood subtype, latent autoimmune diabetes in adults (LADA), shares characteristics of both T2DM and T1DM and is often misdiagnosed as T2DM. This article presents three clinical cases of elderly patients misdiagnosed with T2DM, but who actually had LADA, highlighting the challenges associated with its early identification and the importance of more accurate diagnostic approaches.
糖尿病（DM）是一种慢性疾病，有几种亚型，其病因和临床进展各不相同。2型糖尿病（T2DM）是最常见的诊断形式，与肥胖和缺乏身体活动密切相关，而1型糖尿病（T1DM）在很大程度上起源于自身免疫。一种了解较少的亚型，成人隐匿性自身免疫性糖尿病（LADA），兼具T2DM和T1DM的特征，常被误诊为T2DM。本文介绍了三例老年患者被误诊为T2DM但实际患有LADA的临床病例，突出了早期识别LADA的挑战以及更准确诊断方法的重要性。
