No, your sentence is not correct, if that is what you are asking. I'm also not sure what you are trying to say. You might be trying to say that if something is disgusting, that it makes you want to vomit. You also could be trying to say that something that is disgusting is like vomit. It's not clear. The other answers seem to be guessing what you are trying to say, and then deciding if they agree with that. Odd...

It could be but not necessarily. For example, I find people who lock their dogs outside all day, disgusting. It doesn’t make me want to vomit but I find the behavior objectionable.

You could say it has that nuance! Definitely, "disgusting" is something that repulses you, that makes you put a sour face and look the other way... kind of like vomiting, yeah ;)
