Hello, Thanks for the query.
Carvedilol , you are taking from the last 2-3 yrs and still there is palpitation
Main indication of carvedilol is usually congestive heart failure
and you might have also taken for this.
There is loss of appetite, fatigue
, under weight, fullness in the stomach even after a little food.
All these mentioned complaint are indicators of worsen of congestive heart failure.
Once again you get a blood examination complete, with ECHO, TMT ( tread mill test) .
I doubt any appetizer will work in your's case so please rethink of treatment FROM ANOTHER CARDIOLOGIST. Good luck and best wishes for speedy recovery.
