Creatinine is a nitrogenous waste product produced by muscular activity. Creatinine levels in patients with chronic kidney disease can increase over time. Such increases are a red flag that kidney function is decreasing. As these levels increase, levels of potassium, phosphorus and other nutrients often become abnormal as well. Nephrologists recommend dietary changes to compensate for the kidneys' growing inability to filter the blood.
First, control the intake of salt
Generally speaking, during compensatory stage of renal insufficiency and azotemia stage also have high level of creatinine and are companied with various clinical symptoms, but it is during the moderate damage, patients can adjust the intake of salt according to whether patients have hypertension and edema and adopt low salt diets or non-salt diets respectively.
Second,Potassium
Patients with elevated creatinine often have elevated serum potassium levels as their kidneys becomes less able to remove potassium from the blood. Nephrologists recommend a low-potassium diet when this happens. The National Kidney Foundation suggests that adults with elevated potassium limit their intake to less than 2,000 to 3,000 mg.
The NKF defines high-potassium foods as those with more than 200 mg of potassium per serving. These include potatoes, winter squashes, broccoli and legumes. Better choices are green peppers, white rice, plain pasta, mushrooms, onions, apples and pineapple.
Third,Sodium
One of the most helpful things that people with high creatinine can do to preserve renal function is to control their blood pressures. The kidneys are primarily made from vascular tissue. In addition to renal arteries, the glomeruli, or filters, are simply nests of tiny capillaries. These tissues are destroyed by hypertension, which is endemic in this population. In addition to taking blood pressure medications, eating a low-sodium diet is beneficial. The National Institute of Diabetes and Digestive and Kidney Diseases suggests limiting sodium intake to 2,000 mg per day. It suggests keeping a sodium diary so you are conscious of how much sodium is in your food.
Finally, the supply of the protein
With the development of the disease and the damage of the renal function, many patients have the azotemia and renal insufficiency. In order to control the further aggravation of the renal function and avoid increasing the burden of the kidney, patients should control the intake of the protein and choose high quality protein.
