I don't feel like doing anything, I lost the appetite and sleep. I don't know what's wrong.

我什么事也不想做。我没食欲，还失眠了。我不知道怎么了。

Yeah, you don't look good. I suggest you should run a tape over.

是啊，你看上去气色不大好。我建议你做个全身检查。

重点讲解:

I suggest you do a thorough examination.

I suggest you should run a tape over.

去医院做“全身检查”，书面英语可以说do a thorough examination, thorough有“彻底地，全面地”的意思，口语中老外常用run a tape over表达“进行全身健康检查”。
