[|Human|] My father faced a heart attack few months back then doctors installed a metal stun in his heart. Few months passed. One day he was having fever and we found phemonia captured my father. His one lung was collapsed and lots of fuild was taken out of his lung. Now my father is under medication at home. My father is having swelling in his feets and He cant able to eat food. Doctors says there is a very little problem in his liver. please give us your opinion and what kind of food diet he should go for.
[|AI|]  Swelling in the feet can be due to many causes. His heart, kidneys, lungs and liver should be checked. Even his state of nourishment should be checked. Sitting for long with legs having down can also cause swelling feet. So get him tested thoroughly. Diet will depend on the test results. If all is well then he can have high protein diet with plenty of fruits and vegetables and slight restriction on salt.
