The so-called renal edema refers to edema caused by impaired renal function. This edema has two more obvious characteristics, one is symmetry, one is concave. Renal edema is often the site of the eyelids, lower legs and feet, it’s always symmetrical, there is no situation of swelling of one side while another side is normal.

The so-called finger-concave, press with your finger there will be a pit, and will not immediately disappear. However, the eyelid parts due to loose tissue, prone to edema, such as drinking too much water, poor sleep, rubbing eyes, tears, etc, so do not worry too much.

There are two reasons for renal edema, one electrolyte imbalance, the second is a large number of leaky protein. Electrolyte disorders, especially sodium ion metabolism disorders, can easily lead to imbalance in the crystal osmotic pressure, water is squeezed from the cell to the outside of the cell, the formation of edema; a large number of leaky protein, will lead to decreased plasma proteins, especially the decline of plasma albumin will reduce cause colloid osmotic pressure imbalance, the plasma water will enter a large number of interstitial fluid, causing edema. Therefore, for patients with kidney disease, doctors often recommend eating less salt and eating high-quality protein, one of the reasons is to prevent edema.

Treatment of renal edema

For sodium and water retention caused by edema, diuretics can be used. One of the effects of diuretics is to inhibit renal tubular reabsorption of sodium, reducing sodium retention in the body, thus eliminating edema. In addition, diuretics can also lower blood pressure, it should be taken in the morning, should not be taken before going to bed.

Edema caused by water and sodium retention, you need to supply high-quality protein. High-quality protein refers to easily absorbed by the body's proteins, such as fish, poultry, eggs, milk, soybeans and so on. In patients with kidney disease, excessive protein replenishment can exacerbate protein leakage, thereby increasing kidney damage, and therefore need to control intake, which is the so-called "high-quality low-protein diet." In general, patients with kidney disease daily protein supplement per kilogram of body weight 0.6-1 grams.

For patients with relatively severe plasma albumin decline, artificial protein injection can be used to temporarily increase, but not for a long term. Of course, after edema, the amount of water should be reduced accordingly, but also pay attention to observe the daily urine output. If diuretics and diet can not help urination, dialysis can be considered.
