Ileostomate here but think this can apply to most of us. What do you do if you accidentally swallow something unchewed?

Of course this is to be avoided at all costs but sometimes you choke on air and have to swallow, or cough with a piece of gum in your mouth. And sometimes the mouth just goes on autopilot or the throat decides to claim its catch prematurely.

I have had this happen with minor bites but it's only a matter of time before I swallow something big and I want to be prepared because time can be of the essence.
Has this happened to you? What did you do? Is it ever wise to try to make yourself throw up to prevent a blockage?
Any and all advice appreciated!
