Diet for High Creatinine And BUN

2013-05-01 14:13

High creatinine and BUN can reflect how well your kidneys are functioning.A healthy diet can reduce wastes in blood and improve renal function,thus lowering high creatinine and BUN.

Creatinine is the byproduct of creatine in muscle.After it is produced, it is normally filtered out by kidneys.Thus,it can keep constant levels in right condition.Urea is from the end products of proteins.High levels of urea in blood can cause uremia.It is a disorder involving multiple organs and systems of the body such as anemia,bone disease,nerve damage etc.

High creatinine and BUN indicate serious kidney damage.Therefore,the diet should also be beneficial to improve renal function.Diet for high creatinine and BUN is as follows:

Low-protein diet

High protein consumption can increase the production of urea,thus raising BUN levels.Also,too much protein intake can contribute to high creatinine levels.Meanwhile,high-quality protein should covers 50% of the total protein intake.Beans,nuts and grains have moderate amounts of protein, and fruits generally have no proteins.

Vegetarian diet

Dietary sources of creatine and creatinine are only found within animal products.Therefore, the patients will be reducing the burden of extra creatine and creatinine circulating through the blood by eating a largely plant based diet.


When your kidneys are not working properly, they fail to remove excess fluid from your body.Limiting fluid intake can prevent high blood pressure,swelling and shortness of breath.How much fluid can you take each day? Please consult us for more information.


Fruits are recommended to people with high creatinine and BUN.Fresh fruits are high in vitamins and fibre.These components are beneficial to reduce the risk of developing complications of kidney disease.

High-phosphorus foods

Phosphorus is important to keep bone healthy.However, high levels of phosphorus can cause bone problem and skin itching. Meanwhile, the foods high in potassium should also be avoided as high potassium level in blood can be life-threatening.

The above is a general diet for high creatinine and BUN.As the causes of kidney problem vary, the diet should also be different.
