Hitting meno can cause many intolerances and allergies that we never had before,where I used to be able to eat pretty much anything,nowadays it's a minefield,tomatoes give me awful reflux,which in turn can cause nausea,so although a chore,take note of what you eat,would you consider an intolerance test? I did one a few years back and found I had an allergy to wheat,cut it out of my diet and hey presto,no more bloat,no more stomach cramps.
