Can nephrotic syndrome cause hyperglycemia? it if does, what's the mechanism?

Ideas: If your nephrotic syndrome is due to diabetes, as it sometimes is, this is your answer. If you are being treated for nephrotic syndrome with a glucocorticoid that impairs glucose tolerance, this can explain it. If your kidneys are beginning to fail, there may be some mild glucose intolerance. Only your physician can sort this out. Good luck.
