有月经的女子,在潮经期间感到不同程度的下腹疼痛,这种疼痛是伴随着月经而发生的,所以叫做痛经。痛经只是一个症状,它可以由许多因素引起。有些因素迄今尚未明确,通过一般检查,会发现生殖器官基本正常,并无明显的病变;这种痛经,称之为原发性痛经。有些因素是可以查出来的,如慢性盆器炎、子宫内膜异位症、子宫颈阻塞、子宫后倾等;这种痛经,称之为继发性痛经。从定义上来看,这两种痛经是两种性质的,但是在临床上,一般检查不易做到绝对准确,特别是一些较轻的病变比较难以查出,因而鉴别诊断就不是那么容易。本文的内容是介绍原发性痛经。 Women who have menstruation experience varying degrees of abdominal pain during tidal periods.
