在日耳曼语系的国家中,功能性消化不良通常诊断为“Reizmagen”(意为易激胃),为一种伴有或不伴有原因不明的胸骨后症状的上腹部慢性综合征。按其定义,只有在排除器质性疾病,根据患者病史,且内窥镜、超声波及实验室检查阴性时,才能作出此诊断。 In countries of Germanic origin, functional dyspepsia is commonly diagnosed as “Reizmagen” (a form of irritable stomach), a type of chronic upper extremity syndrome with or without unexplained symptoms of the sternum. By definition, this diagnosis can only be made if organic disease is ruled out, based on the patient’s history, and endoscopy, ultrasound, and laboratory tests are negative.
