Many types of nephrotic edema, especially nephrotic syndrome. In the end what is the harm of renal edema? How to treat it?

The causes of edema in patients with kidney disease can be divided into the following three categories:
1, decreased renal function
One of the main functions of the kidney is drainage, the blood through the glomerular filtration, the formation of the original urine, and then reabsorbed through the renal tubules to form urine. When the glomerular damage is serious, a serious decline in filtration function, resulting in water can not be normal metabolism, there will be oliguria or even no urine, and accompanied by edema.
2, colloid osmotic pressure imbalance
This is mainly caused by protein loss. Large numbers of patients with nephrotic syndrome leak protein, resulting in lower plasma albumin, while plasma albumin is the key material to maintain the balance of colloid osmotic pressure. Once the colloid osmotic pressure imbalance, the blood vessels will flow into the blood vessels, causing edema.
3, crystal osmotic pressure imbalance
This is common in patients with kidney disease, "Shuinazhuliu", when the electrolyte imbalance, abnormal metabolism of sodium ions were forced to stay in the body, will lead to imbalance in the crystal osmotic pressure, the intracellular water flow into the cell, causing edema.
Treatment of renal edema
Once the cause of renal edema is established, the treatment can be determined.
① edema caused by decreased function, in addition to restrictions on drinking water and the use of diuretics, some patients in severe cases also need dialysis drainage;
② a large number of leaky protein-induced edema, to find ways to improve the plasma albumin level in order to fundamentally solve the problem of edema;
③ water and sodium retention caused by edema, to find a way to balance the electrolyte, mainly through the regulation of drugs and diet, while diuresis.
First swelling, or eliminate urine protein?
For patients with nephrotic syndrome, a large number of urinary protein and high degree of edema exist, which should be solved?
Generally think that, since this edema is caused by a large leak of protein, is it right? Urinary protein should be used to eliminate hormones, and then solve the edema ah?
Not
Because the hormone will cause sodium and water retention, so that patients swollen swollen on the swelling, and high edema easily lead to acute heart failure and acute pulmonary edema, which are deadly threat, it should be the priority of swelling.
The swelling method is not simply the use of diuretics, but the importation of artificial protein, the first restoration of colloid osmotic pressure balance, and then to use diuretics.
