乘飞机时脚肿：是否应引起注意？

什么原因引起乘飞机时腿肿和脚肿？

乘飞机时腿脚肿胀是一种常见现象，而且通常无害。最有可能的原因是，在乘飞机期间久坐不动。

久坐时双脚着地会导致血液在腿部静脉中积聚。就坐时的腿部姿势也会增加腿静脉的压力，促使液体从血液进入周围软组织，从而导致肿胀。

深静脉血栓（DVT）是一种危险的血栓，有时可能引起腿部肿胀。但对于健康的人来说，乘飞机期间出现 DVT 的风险极低，尤其是在航班飞行时间不到四个小时的情况下。一般而言，航班时间超过 12 小时会使出现 DVT 的可能性增加。

在长途飞行中穿着压力袜可以减轻腿部肿胀，降低血栓风险。压力袜可对小腿施加压力。

如果您在长途飞行后的两周内发现一条腿肿胀未消失或开始肿胀，请立即进行健康检查。此类肿胀可能是 DVT 或其他需要治疗的医疗状况的症状。如果您出现血栓的风险较高，请在乘飞机前先咨询医疗护理团队的成员。
