After the serum creatinine increases, the diet of kidney friends needs to be adjusted. Remember 5 points, and you can feel relieved when you eat it.

The change and development of chronic kidney disease is a dynamic process. The patient's blood pressure, edema, urine protein, serum creatinine, serum potassium and serum uric acid will change and fluctuate. There is no change, while some patients' condition changes greatly or progresses rapidly. Among them, in terms of renal function, serum creatinine may rise slowly or rapidly, indicating that the disease has further progressed, complicated by or progressed to renal failure, or complicated by acute kidney injury, or progressed to chronic renal insufficiency. At this time, the medication of patients with kidney disease needs to be further adjusted under the guidance of the doctor, and the patient's diet should also be adjusted and changed accordingly, and it cannot remain at the previous stage.

It can be said that when the serum creatinine rises, kidney friends need to remember five points to adjust their diet, so that they can eat with confidence.

1. Appropriately reduce protein intake

Different from normal serum creatinine, when serum creatinine rises, it indicates that renal function is declining, and the protein intake in the diet of patients with renal disease should be appropriately reduced to reduce the burden on the kidneys. The glomerular filtration rate (eGFR) is estimated from the serum creatinine test results, or the glomerular filtration rate (GFR) is obtained by direct examination, and based on this result, the daily protein intake should be calculated. The lower the GFR, the less protein a patient should consume per day. Generally speaking, according to the GFR from 90ml/min to 15ml/min, the daily protein intake of patients should be reduced from 1.2 grams per kilogram of body weight to 0.5 grams, so that the specific amount to be eaten can be determined. The sources of protein are mainly staple foods such as rice noodles, milk, soy products and animal meat.

2. Ensure that high-quality protein can not be less

After the serum creatinine rises, too much daily protein intake will inevitably aggravate the already damaged kidney function. Excessive daily intake of plant proteins such as rice noodles are non-high-quality proteins. After they are absorbed by the body, they will produce more "wastes", which are more likely to increase the burden on the kidneys. After high-quality proteins such as milk, soy products and animal meat are absorbed by the human body, they have high bioavailability and produce less "waste", which is more conducive to protecting damaged kidneys. Therefore, when serum creatinine increases, under the premise of controlling the total protein intake, it is ensured that the proportion of high-quality protein cannot be less than 60%, which can ensure the demand without increasing the burden on the kidneys.

3. Malnourished patients do not eat less the better

For malnourished patients with kidney disease such as obvious weight loss or low plasma protein, even if the serum creatinine is elevated, they cannot strictly follow the above dietary requirements. . This is because malnourished patients with kidney disease will also have poor resistance and are more likely to be complicated by infectious diseases. Properly increasing the intake of protein (especially high-quality protein) can significantly improve the patient's immune function, thereby enhancing disease resistance without increasing the burden on the kidneys.

4. Salt control and purine control are necessary

After serum creatinine is elevated, patients with renal disease need to control the intake of salt and purine regardless of the presence or absence of hypertension and hyperuricemia. This is because once serum creatinine increases, the condition of patients with chronic kidney disease will further develop, and at the same time, it is more likely to develop renal hypertension and secondary hyperuricemia, and even cause hypertensive cardio-encephalopathy and cerebrovascular disease. Accidents and serious complications such as gouty arthritis. A low-salt and low-purine diet can reduce the risk of these complications. In principle, the daily intake of salt should be controlled at 3.0-5.0 grams, and at the same time choose foods with lower purine content, so that the purpose of controlling salt and purine can be achieved.

5. There may be other dietary requirements depending on the specific condition

After the increase of serum creatinine, hyperkalemia and hyperphosphatemia may also occur. Originally, there may be hypokalemia, hyponatremia, hyperlipidemia and elevated blood sugar, etc., which need to be based on the results of regular inspections Make appropriate dietary adjustments. It is not to say that if the serum creatinine is high, it is necessary to limit the intake of potassium in the diet. Only those patients with renal failure who are prone to hyperkalemia need to strictly limit the fruits and vegetables high in potassium. In patients with renal failure who often experience hypokalemia, it is necessary to appropriately increase the intake of potassium in the diet. In patients with renal failure with low blood sugar, the intake of carbohydrates can be appropriately increased to provide more "energy"; in patients with renal failure with high blood sugar (such as diabetic nephropathy complicated with chronic renal failure or diabetes complicated with chronic kidney disease), the The intake of carbohydrates in the diet needs to be reduced. In short, it needs to be determined on a case-by-case basis.

Therefore, as long as you remember the above five keys related to diet, kidney friends can feel at ease after eating with elevated serum creatinine.
