让张学友在演唱会上晕倒的“耳水不平衡”是什么病？

62岁的张学友今年6月开始“张学友60+巡回演唱会”。近日他巡演来到马来西亚，8月13日举办第三场演唱会时，现场发生意外：

在演唱《只想一生跟你走》时，张学友突然失去平衡摔倒在舞台上，但几秒之后，他用手撑起身体，站起来继续演唱。

Hong Kong singer Jacky Cheung lost his balance for a split second and fell on stage during his concert in Malaysia over the weekend.

The veteran artiste was performing for the third night of his 60+ Concert Tour at Axiata Arena in Kuala Lumpur on Sunday.

Cheung was seen walking slowly down a small slope on stage while performing the song "Just Want To Spend My Life With You" when he appeared to become dizzy, causing him to lose his footing and sit down on the ground.

Despite the mishap, the 62-year-old quickly regained his composure and continued singing the hit song after a brief pause.

Later on in the concert, Cheung addressed the incident to the relief of the audience. He shared that he has been living with Meniere's disease since his youth. This ailment causes dizzy spells as a result of an inner ear disorder.

据当地媒体报道，事实上，在马来西亚的第二场演唱会上，张学友就因为“耳水不平衡”头晕推迟了8分钟开场，连续两日头晕不适，“歌神”的身体状况引发歌迷担忧。

According to Malaysian media, the concert on the previous day was delayed by eight minutes due to a relapse half an hour before the show started.

在第三场演唱会上，张学友摔倒之后表示，耳水不平衡导致的头晕问题又严重了一些，“昨天是演唱会前发作，从来不曾在演唱会（期间）发作，现在头晕啦，天旋地转、晕晕的……”

他称很多时候要闭起眼睛，才不会那么晕：“没有办法望着你们，但看不到你们我又不开心，你们一直见到我不睁开眼，也会心里不舒服吧！”

张学友透露，自己评估过声音并未受到影响，还笑称：“这是演唱会嘛，不是演跳会，是不是可以坐着唱，先让大家习惯一下我80岁和90岁时候的样子。”

Cheung also revealed that he had to partially close his eyes during the performance to alleviate the dizziness. In a lighthearted manner, he joked, "I am not happy if I can't see you, and you'll feel uncomfortable if I have my eyes closed." He explained that the condition affects his dancing but not his vocals.

Meniere's disease is a disorder caused by a build-up of fluid in the chambers of the inner ear.

Medication for motion sickness might help with your vertigo, and medicine for nausea might help with vomiting if that's a side effect of your dizziness. A few patients won't respond to any of these treatments and will need surgery. 

In addition to eating a low-salt diet, you may want to cut down on alcohol and caffeine. Tobacco use also can be harmful, as cigarettes have chemicals in them that restrict blood vessels.
