My dad had Coronary artery bypass surgery on 4rt of Jan. he had three bypass. he is 65yrs of age. His reports are all normal. after 4 weeks of surgery-his apetite improved and his enthu also improved. we all felt he is coming back to normal. But now since 1 week, that is after 6 weeks of surgery he is suffering from hiccups, vomiting and tiredness. doctor first gave panarom then domped and chloropromazine and for every tablet hiccups will stop in 15-20mins. but he is feeling irritated and lost enthu completely...he stopped eating because of depression. Doctors also tell that these hiccups, vomitings are very much normal in all CABG patients and it indicates successful ness of surgery. please let me know whether it is true. when all these troubles go and he will come back to normal?. any other suggestions to improve his condition...Thanks in advance
