hello sir ,
You father is 82 years old , quiet old enough and he also had bypass surgery
and stage 4 kidney
problem . The loss of appetite , weakness and dizziness
all are related to his comorbid conditions related to heart , kidney and age. He is adviced to take digoxin
indicates his pumping action of heart is weak , which also causes these all symptoms . Stage 4 kidney disease indicates uraemia , which also causes the mentioned symptoms. The age itself causes all these symptoms. Thus i advice him for take regular medication and multivitamin
syrups or tablets , which helps to relieve the symptoms and feeling comfortable .
