thanks for the question . as you are 61yrs old it suggests that having too much of fatty food can lead to abdominal discomfort because as we age the capacity to digest decreases. I would suggest you to have a diet which has more fibres (green leafy vegetables , fruits , salads) and to cut down on fatty foods . you could also consult a physician and he may prescribe you better medications like proton pump
inhibitors which bring down gastritis
(could be the reason for your pain).also you can consult a gastroenterologist
if the pain keeps recurring for further investigations like endoscopy(non invasive procedure).
I hope I have answered your doubt.
