CKD treatment options
Treatment of chronic kidney disease (CKD) varies according to the severity. However, steps can be taken in all cases to: control hypertension, correct salt and water imbalance, treat urinary tract infections, and reduce risk of heart and blood vessel diseases. Most people with CKD will be able to slow down progression through regular check-ups and medication intake.
In addition to the measures above, the following treatment options are available:
- Conservative treatment
- Renal replacement therapy (RRT)
- Kidney Transplantation
Conservative treatment in the CKD predialysis phase
A comprehensive conservative treatment of chronic kidney disease (CKD) without dialysis uses dietary interventions and medications from earlier stages of the disease until start of dialysis. Most people with CKD will be able to control their condition with medication and regular check-ups.
The conservative, non-invasive treatment aims to:
- slow the progression of the disease and thereby postpone the onset of renal replacement therapy (e.g. dialysis, transplantation)
- avoid or attenuate the development of secondary diseases (e.g. bone disease, cardiovascular disease).
Dietary interventions, in particular the restriction of protein intake (low/very low protein diet) is an important part of conservative CKD treatment. Depending on the severity of this protein restriction, a supplementation with keto-analogues might be indicated. Clinical studies have shown that this combination may postpone the start of dialysis.1
The role of proteins in CKD
Proteins are important for various functions in your body including build-up of muscles and reactions of the immune system. Eating the right amount of protein is therefore especially important for sufferers of CKD. Over-consumption of protein, when your kidneys are weak, will lead to a build-up of nitrogen-containing waste in your body. This build-up can have harmful consequences such as: nausea, weakness, tiredness, shortness of breath and reduced appetite.

Keto acids supplemented low protein diet
Keto acids, are nitrogen-free precursors of essential amino acids. Keto acids are converted to the respective amino acids in the body. In this way, no additional nitrogen intake occurs and the formation of nitrogen-containing waste products is reduced.
It is important to mention that keto acids do not work on their own. Keto acids are essential supplements to a protein restricted diet. Find out more about the nutritional management as well as specific diet recipes in chronic kidney disease.
Benefits of keto acid supplementation
Early treatment of advanced CKD patients with keto acids may delay the start of dialysis.1 Keto acid supplementation is a safe and effective way for patients on a protein restricted diet to ensure a sufficient daily intake of essential amino acids.
Renal replacement therapy (RRT)
In stage 5, most patients need a renal replacement therapy, such as dialysis or kidney transplantation.
Dialysis (haemodialysis & peritoneal dialysis)
In dialysis, waste is washed out and water is withdrawn from the blood. The two most widely used dialysis techniques in CKD are haemodialysis and peritoneal dialysis. Dialysis involves the removal of urea, and stabilisation of water and electrolyte levels in the blood via a dialysis machine.
This treatment option affects a patient’s quality of life, as they must be connected to the dialysis machine 3 times a week for 5 hours (haemodialysis) or exchange bags every 4-6.

With a kidney transplantation, the transplanted organ takes over the role of the previous damaged kidneys. For a variety of reasons (not enough organ donors, health of the recipient etc.) many patients cannot be treated with kidney transplantation. Furthermore, several side effects can occur, such as a chronic defense reaction of the body´s immune system, as a result of the transplanted organ.
