Causes of proteinuria

summary

I felt a little pain in my waist during the new year. Then I went to the hospital for an examination and said that the urine protein was high and 3 +. After treatment, I got a lot better. Let's talk about the reason for the 3 + urine protein.

Causes of proteinuria

Reason 1: glomerular proteinuria, seen in acute glomerulonephritis, various types of chronic glomerulonephritis, IgA nephritis, occult nephritis. Secondary autoimmune diseases such as lupus nephritis, diabetic nephropathy, purpura nephritis, renal arteriosclerosis, etc. Metabolic diseases are found in gouty kidney. Intense exercise, long-distance March, high temperature environment, fever, cold environment, mental tension, congestive heart failure can also appear proteinuria.

Cause 2: renal tubular proteinuria, the most common causes of interstitial nephritis, renal vein thrombosis, renal artery embolism, heavy metal salt poisoning, etc.

Reason 3: renal tissue proteinuria, also known as secretory proteinuria. Because in the process of urine formation, the protein produced by renal tubular metabolism infiltrates into the urine.

matters needing attention

Warm reminder: the 24-hour monitoring results of normal people show that the protein in the urine is generally 40-80 mg, which is often not detected when testing. The two plus signs of urine protein mean that the 1L urine of the tested person contains 1.0-2.0g protein, which belongs to the disease of the body.
