Sodium: Sodium is a mineral found in many foods, as well as in table salt. Too much sodium in your diet can contribute to high blood pressure. When your kidneys aren’t working as well as they should, too much sodium can also contribute to fluid retention, swelling, and shortness of breath. Limiting the sodium in your diet can help to lower your blood pressure, and can help to avoid fluid retention. A common goal is to aim for less than 2,000 mg of sodium per day. Familiarizing yourself with nutrition labels can be helpful in identifying the content of foods.
Potassium: Potassium is a mineral found in many foods. In normal ranges, it contributes to appropriate function of your cells, particularly muscle cells. With severe kidney disease and kidney failure, the kidneys may lose their ability to balance the potassium in your body. In this case, potassium can build up in your body to a dangerous level, and can cause muscular dysfunction or even death. Familiarizing yourself with nutrition labels can be helpful in identifying the content of foods.
Phosphorus: Phosphorus is a mineral found in your bones, as well as in many foods. In normal amounts, it can help keep your bones and body healthy. With severe kidney disease and kidney failure, the kidneys may lose their ability to balance the phosphorus in your body. Excess phosphorus can weaken your bones, and can cause calcification of your blood vessels, heart valves, and other tissues. Often, people with severe kidney disease or kidney failure need to take medications to “bind” the phosphorus in foods, to help your body get rid of it. Phosphorus is not listed as an amount on nutrition labels. It is necessary to review the ingredient list to identify sources of phosphorus.
Protein: Our bodies need some amount of protein to maintain healthy function and nutrition. Protein byproducts are removed from the body by the kidneys. For patients with kidney disease, sometimes limiting the amount of dietary protein you take in can slow the decline in kidney function. Sometimes, we will help to identify a limit to how much protein you should consume on a daily basis.
Oxalate: The most common type of kidney stones are calcium oxalate stones. Oxalate is found in many foods in varying amounts. Limiting foods that are particularly high in oxalate may help to limit stone formation.
Purine: People with chronic kidney disease are at increased risk of developing gout. Kidney disease can contribute to higher uric acid levels, which in turn increases the risk for gout. If you have elevated uric acid levels or a history of gout, pursuing a diet that limits the amount of purine you take in can be helpful
