Hello from JA
A scan does not show kidney function, it would only show structural abanormalities.
Creatinine that is higher then high normal can represent up to 30 to 50% damage to the kidneys.
The most common causes are high blood pressure, diabetes, and autoimmune kidney diseases. The last one requires the renal specialist for diagnosis.
Whey protein is somethin you should stop
The least protein possible for health is what is needed in kidney disease, NOT protein supplements.
A vegetarian diet, in fact, is ideal.
OK. If you have further questions or details, use reply to expert.
Otherwise please choose a positive rating [smiley face or accept]. But, still come back if you need to…think of something later, etc. Bonuses are appreciated.
