Why do you think caused your GERD/LPR?

Curious to see if there’s a link in what people have to say as a lot of us seem to have developed this overnight or over one bad meal. For me personally I think this stems from having a bad fast food bender where I ate a bunch of pizza one night that gave me the first real experience of acid reflux I’ve ever felt,followed by a greasy breakfast at a diner. That combined with the fact that I am overweight is what I think made develop this.
