Is urine protein high 3 + serious?

High urine protein 3+ is usually judged according to the actual situation.

If the patient does not fast according to the doctor's advice before the examination, eating a lot of protein-rich foods, it is easy to cause the urine protein test result to be 3+. Over time, excess protein will be excreted, and urine protein will return to normal range by itself. This is usually not serious. If the patient did not eat any food before examination, the urine protein test results showed 3+, but also edema, renal discomfort and other abnormal symptoms, suggesting that it may be related to pyelonephritis, glomerulonephritis, nephrotic syndrome and other diseases, which are generally more serious at this time. If the disease progression is not intervened as soon as possible, it may cause metabolic acidosis, water and electrolyte disorders, acute renal function damage, chronic renal failure, hypertensive encephalopathy and other complications.
