Kidney Function

The function of the kidneys is to filter out water soluable toxins from the blood.  They must also maintain the correct acidity/alkalinity and salts concentration in the blood.  Chronic Kidney Disease is a degenerative condition in which the filtration capacity of the kidneys deminishes faster than 'age appropriate'.

At maximum through put, adult kidneys should filter approximately 100ml of blood per minute.  It is however generally accepted that we may lose 1ml per minute capacity per year. 

However, a person at the age of 25 with healthy kidneys may naturally have a lower than average filtration rate, and therefore start with as little as 80ml per minute maximum filtration.  After 25 years, this person may only have a filtration capacity of 55ml per minute (80 - 25 = 55ml) and still not be suffering Chronic Kidney Disease.  It is important to understand this before observing the chart further down this page.

To Maintain Optimum Kidney Filtration Rates

Cleansing the kidneys twice yearly with a blend of traditionally used kidney herbs may dramatically improve kidney function according to Dr Hulda Clarke in her book Cure for All Diseases

Kidney Cleanse

in addition to the Kidney Cleanse Herbs, recent research in London has suggested that the need for Chronic Kidney Disease related dialysis may be postponed with the consumption of Sodium Bicarbonate.    Read the Times Online article here.

Sodium Bicarbonate

Another obsesrvation being made by Doctors treating Autism is that phosphorus may be a key not only to improving our cellular hydration but also to retoring kidney function.  When drinking an electrolyte rich in phosphorus the urine becomes both darker and stronger smelling.  This is a clear indication that toxins are being more effectively shuttled out.  Dramatic improvements in eGFR (estimated Glomerular Filtration Rate) have also been reported.

The 5 Stages of CKD (Chronic Kidney Disease)

The kidneys' filtration rate is referred to as the eGFR (estimated Glomerular Filtration Rate) Chronic Kidney disease is ranked in stages, from 1 to 5 according to the eGFR as follows:

• stage 1 is eGFR greater than 90 mls per minute.  However - if all the other kidney tests are normal, there is no CKD and this is only a lower than average normal rate.

• stage 2 is eGFR 60-90 mls per minute. Again there must be some sign of kidney damage.  If all tests are normal, there is no CKD.
• stage 3 is eGFR 30-59 mls per minute.  This is a moderate reduction in kidney function.
• stage 4 is eGFR 15-29 mls per minute is a severe reduction in kidney function.
• stage 5 is eGFR of less than 15 mls per minute, denoting kidney failure, possibly needing dialysis or a kidney transplant.
