I am a 60 year old female. for the last two years I have been having problems wehnever I consume any drinks with milk. I burp excessively with sourish regurgitation. At times I experience a wholemouth full of regurgitated liquid. Often I have a bloted stomach after a meal. When I take lunch in the afternoon I feel very exhausted after it and need to lie down for sometime. What is wrong here? Please advise
