The presence of pruritus is due to the fact that phosphorus is at work. Studies have shown that renal function in normal or mild abnormalities, the kidneys can regulate the metabolism of phosphorus, and when the creatinine more than 200 after the kidney regulation problems, it will occur hyperphosphatemia.
The risk of hyperphosphatemia
Hyperphosphatemia will not only make kidney failure patients feel itchy body, but also cause hypocalcemia, leading to bone calcification disorders, and then cause secondary hyperparathyroidism. This is also an important complication and pathogenic factor in patients with renal failure.
So for patients with kidney disease,what type of blood phosphorus should be controlled?
When the blood phosphorus is greater than 1.45mmol / L, we call hyperphosphatemia. Nephrotic patients from the beginning of 3, you need to pay attention to the issue of phosphorus.
Nephropathy 3-5 (undiluted): blood phosphorus maintained at normal (0.87-1.45mmol / L) range.
Nephropathy 5 (dialysis): blood phosphorus maintained at (1.13-1.78mmol / L) range.
First of all from the diet control, but the way to limit the phosphorus to be correct, to the appropriate "taboos", both to ensure nutrition and phosphorus. Not blindly do not eat high phosphorus foods, but to master the skills.
Such as meat, high-quality protein rich, but the phosphorus content is also high, then you can use water boil about, in cooking, in order to achieve the purpose of phosphorus. Do not let the protein intake enough to offset the advantages of limiting phosphorus!
How to treat after itching symptoms?
When the blood phosphorus has been high when the symptoms of itching, we must first check to confirm whether it is uremic itching skin rash, and then according to their own situation for treatment.
Non-uremic skin itching, can be a specific skin treatment or systemic treatment. Uremic itching, can improve the quality of dialysis, dialysis dose to increase the way to improve the part of the dialysis of patients can be changed to daytime dialysis.
