Hello and welcome to HCM.
Sorry to know the condition your friend is going through.
Nutritional problem in congestive
heart failure may be because of dietary restriction in form of low sodium diet,disease process itself or due to
diuretic therapy.
If I were your treating doctor,I would recommend,
-Eat small frequent meals instead of a large one.
-Have whole grain cereals,dark green leafy vegetables,almonds in routine diet to make up for
vitamins and minerals.
-Keep daily intake of salt less than 2 gram/day by consuming fresh vegetables,fruits,low fat lean meat.Avoid using packaged and processed food.
-Psychological support and encouragement is needed from the closed ones for building up the positive outlook of patient.
-Be compliant with all medication.The appetite and nutrition will improve as the disease process slows down cause of medications.
Hope this information helps.
Thanks and regards.
