Apples do cause gas because of the Pectin in them. This might be the cause of the bloat. Try some gas-x or phazyme and see if that works at all. That or cut down the amount of apples you eat daily for a week and see if that helps.
According to the website, www.pdrhealth.com/drug_info/nmdrugprofiles/nutsupdrugs/pec_0198.shtml, Pectin may cause such gastrointestinal symptoms as flatulence, cramps, gas and diarrhea.
So that is what it may be as well.
