Can a Specific Diet Lower Creatinine Levels?

During physical activity, muscle cells break down and form a waste product called creatinine. When the kidneys function normally, they remove creatinine from the bloodstream and eliminate it in the urine. When kidney function declines, creatinine builds up in the blood stream and causes problems that include fatigue, itchy skin and nausea. Special dietary restrictions help reduce creatinine levels.

Features

This type of diet restricts the intake of protein, phosphorus, potassium and sodium. In patients with advanced kidney disease, a diet designed to lower creatinine levels also restricts fluid consumption. Eating less protein reduces the workload of the kidneys, while eating less sodium, phosphorus and potassium prevents these substances from building up in the bloodstream. Reducing fluid intake prevents fluid from building up in the bloodstream, which reduces blood pressure and prevents swelling.

Effects

With a reduced workload, the kidneys do not have to work as hard to maintain normal fluid and electrolyte balances. Eating less protein reduces the amount of creatinine the body produces. Both of these things make it easier for the kidneys to filter creatinine out of the blood and reduce creatinine levels. Following this type of diet may also slow the progression of kidney disease.
