When to Restrict Protein with Nephrotic Syndrome

When to Restrict Protein with Nephrotic SyndromeDo you know when to restrict protein with Nephrotic Syndrome? Some patients with Nephrotic Syndrome are told to limit their protein intake, so as to avoid adding extra burden on kidney. However, some others are told to ingest protein normally. Why is this? And when to restrict with Nephrotic Syndrome?

Why is protein limitation needed in some cases, and not in some other cases of Nephrotic Syndrome?

Nephrotic Syndrome is a problem marked by massive proteinuria which appears as the mechanism barrier and charge barrier of glomerular filtration membrane are impaired seriously. For patients with Nephrotic Syndrome, if their proteinuria symptom can be controlled well, then they need to limit protein intake according to the residual kidney function. However, for patients who are insensitive, it is hard to bring their proteinuria under control. Under such a condition, they usually need not to limit protein intake, because protein limitation may cause further worsening of hypoproteinemia which is usually resulted from severe protein leakage.

How much protein is needed by Nephrotic Syndrome?

For these who need not to control protein intake, they generally need to ingest 0.8 gram of protein per kilogram of body weight per day. And for these who are told to limit protein intake strictly, exact protein intake is based on the residual kidney function.

In general, 0.4 to 0.6 gram of protein is needed per kilogram of body weight a day, if their illness stays in stage 3 to stage 4. However, if Nephrotic Syndrome has developed to kidney failure stage or stage 5, 0.2 gram of protein per kilogram of body weight per day is needed for these who have not started dialysis. If dialysis is unfortunately needed, much more protein (1.2 gram of protein per kilogram of body weight per day) is needed, because for them, some protein may be lost during dialysis process. The purpose to ingest much more protein is to replenish the one lost in dialysis.
