Hi. My mother recovered recently from COVID undergoes dialysis three times a week which started five years back with a frequency of once a week in 2016. She has high BP and post COVID her lungs strength has decreased. Recently, due to fluid overload her oxygen saturation dropped with abnormally high and varying pulse. As a emergency treatment isolazine is started with her regular BP medications. I wanted to know about a heart renal friendly diet that could be followed in detail with what to eat and what not to eat since High Potassium and Sodium with high level of fluids already created a critical situation once and I would like to avoid it with the best possible options. A regular diet rich in protien, low in potassium and phosphorus, low salt suitable for both affected kidney and heart.
