Hi and welcome to HCM.
It definitely indicates some stomach issue and i think it may be more hiatal hernia
than ulcus or gerd
. this would exlain most of your symptoms and gastroscopy should be done to evaluate it.if negative,you should do colonoscopy
and ct scan
to rule out some other abdominal patologies. Till that try to change your dietary habits,eat smaller meals,avoid stomach irritating food and drinks especailly alcohol nad carbonated beverages.
Wish you good health.Regards
