Kidneys and Protein...Please Help?

[HappyMeNow]

I am caught in a blur when it comes to what kind of renal condition should be limited protein, or any disease process that should have limited protein.

Can someone summarize for me? Questions about menus in general have me

Hi Happy! In short, you limit protein for all kidney patients, except if they have Nephrotic Syndrome. In the case of NS, you'd recommend a diet high in protein because they're losing it so rapidly through the "leaky" glomeruli. Hope this helps!

If nothing else about menu items, you should remember this one since it gave you so much trouble! Good luck.

Patients with cirrhosis of the liver should have lean proteins. In more advanced cases of cirrhosis, all protein might need to be limited.

Acute Renal Failure and Chronic Renal Failure- Low Protein Diet but still provide protein with high biologic values (eggs, chicken)

Acute Glomerulonephritis- Low Protein Diet

Reason: Kidney fails to excrete protein waste products and may cause a build up of urea (protein yields to ammonia-toxin, which is then processed by the liver to be turned to urea-more tolerable substance)....Urea is an irritant to the heart, GI and skin.

Liver Cirrhosis- as what has been mentioned above, in the early stages of Cirrhosis client is encouraged to increase intake of protein. However, as the disease progresses, the risk for hepatic encephalopathy also increase. It is the liver which converts ammonia (protein waste) to urea and if it fails to do so then ammonia build up ( which is toxic to nervous system) can happen.

Parkinson's Disease- Low Protein Diet

Reason: Protein increases the level of L-Carboxylase OUTSIDE the Blood Brain Barrier. L-Carboxylase is the one which converts Levodopa to Dopamine. So if there is increased L-Carboxylase outside the brain, there will only be a little amount available to go INTO the Brain. We want Levodopa to go INTO the brain first before it gets converted to Dopamine, so we restrict Protein.

----------

Nephrotic Syndrome- also a renal disease but unlike the others, it requires Hi-CHON diet.

Reason: There is massive injury to the Glomeruli that enables Macromolecules like Protein to escape. This is not just a type of Proteinuria, but MASSIVE proteinuria occurs. As a result, albumin levels as well as Antibodies (AB are made from protein) also decreases. The body tries to compensate with Liver synthesizing Lipoprotein which is composed of Protein and FATS. Increased Fats lead to Hyperlipidemia. So also remember to DECREASE Fat Intake with Nephrotic Syndrome too...

Hope this helps you, I really hate diet questions too, that's why I focus on them. Good luck to us :)
