Involuntary weight loss is a common complaint among patients over 40 years of age. Few studies concerning the etiologies of weight loss, however, have been published. This article reviews two recent studies that address common causes of unintentional weight loss. In these investigations, almost half of the patients claiming significant weight loss had no decrease in weight at all. In 35 percent of patients with true weight loss, no physical source was found after six months of follow-up. Of those in whom a cause of weight loss was discovered, the etiology was usually apparent after a brief history, physical exam and screening laboratory evaluation. Common causes of involuntary weight loss are discussed. Guidelines for evaluation of the patient who complains of weight loss are offered.
非自愿性体重减轻是40岁以上患者的常见主诉。然而，关于体重减轻病因的研究发表较少。本文综述了两项针对非自愿性体重减轻常见原因的近期研究。在这些调查中，几乎一半声称体重显著减轻的患者体重根本没有下降。在35%真正体重减轻的患者中，经过六个月的随访未发现身体原因。在那些发现体重减轻原因的患者中，病因通常在简短的病史、体格检查和筛查实验室评估后就很明显。本文讨论了非自愿性体重减轻的常见原因。并提供了对主诉体重减轻患者的评估指南。
