According to the study, proteinuria does cause edema. So how does it cause edema? Look at the following analysis.
1. Proteinuria leads to hypoproteinemia, resulting in decreased plasma colloid osmotic pressure
Once the kidney disease is found, the protein components in the blood of the patient will pass through the damaged kidneys. The body lost a lot of protein, the body in a negative nitrogen balance, the formation of hypoproteinemia. Hypoproteinemia will lead to decreased plasma colloid osmotic pressure in patients with nephropathy, so that the blood vessels within the patient's blood vessels will move toward hypertonic interstitial fluid, resulting in edema.
2. The formation of proteinuria to reduce the body's effective blood volume
Nephrotic patients with proteinuria, the body of hypoglycemia, plasma moisture will be moved out. Therefore, the water leakage of blood, the patient's effective blood volume will be greatly reduced. The human brain receives a signal of reduced blood volume, which initiates the renin-angiotensin-aldosterone system (RAS system) in the patient, resulting in an increase in renal tubular reabsorption of sodium and water. On the other hand, the signal will cause the kidneys to reduce the discharge of sodium. Two aspects of the joint role of patients with kidney disease in a large number of sodium, water retention, eventually leading to edema of the body.
In summary, you should have a general understanding of proteinuria caused by edema, if you are a kidney disease patients, once found themselves suffering from proteinuria, must be treated early. Similarly, for patients with proteinuria edema in patients with kidney disease, effective treatment can also eliminate proteinuria and edema, control the disease.
