How Much Sodium Should I Eat in Stage 4 Kidney Failure

How Much Sodium Should I Eat in Stage 4 Kidney FailureHow much sodium should I eat in stage 4 kidney failure? One patient asked. People with stage 4 kidney failure are often required to eat a limited diet to prevent further kidney damage. Today, let’s talk about sodium intake in detail.

Why should people limit sodium in stage 4 kidney failure?

In stage 4 kidney failure, kidney function is severely damaged. So kidneys are not able to finish their work. One of the important works of kidneys is to keep balance of water and electrolyte, especially water and sodium to prevent water-sodium retention. The damaged kidneys fail to do this work. So the water volume and sodium amount will be increased, causing water-sodium retention.

It is reported that even if patients have no symptoms like swelling, heart failure, there is much water in blood than the normal people. Chronic water-sodium retention will trigger a series of problems, such as rising the blood pressure, increasing the proteinuria and accelerating the progression of kidney failure, etc.

How much sodium should I eat with stage 4 kidney failure?

From the above we can see that it is important to control the sodium intake to decrease the potential risks. Studies show that limiting sodium intake is helpful to lower the blood pressure, decrease proteinuria and slow down the progression of the illness.

The most effective way to control the amount of sodium is to control salt intake. The main ingredient in salt is sodium. Kidney doctor suggests that the daily intake of sodium should be limited to 5-6g. If you are accompanied by high blood pressure and water-sodium retention,  sodium intake should be no more than 2g per day. So it depends on your own illness condition.

To well control the sodium intake, you should try to avoid processed meats, canned soups, fast foods and restaurant foods in your daily life. Keeping a healthy diet is a good start to fight against the disease! Any questions? Send me an email to for a reply!
