Can lisinopril cause gastrointestinal issues?

yes, that is one reason i quit it.

In the past I have taken this drug and not ever noticed this kind of problem but I think it's important unless you are otherwise told not to that with this and all other medications that if you put a piece of toast or just a snack that it can prevent something like this from happening but if this is a problem for you despite trying a small snack then this may be somethng that you need to discuss with the prescribing doctor, there are many alternatives but it may just be a passing thing. best wishes, Caringsonbj (Billy)
