The presence of high urinary immunoglobulin G may be caused by nephrotic syndrome and glomerulonephritis.
Immunoglobulin G is a large molecule, and elevated levels of immunoglobulin G in urine usually indicate significant damage to the glomerular filtration membrane.
In patients with nephrotic syndrome, immune complexes are formed in the body, which damage the glomerular filtration barrier, and a large amount of proteinuria occurs, which is non-selective proteinuria, making the urine immunoglobulin G high.
Glomerulonephritis is caused by a variety of causes of glomerular inflammatory lesions, resulting in damage to the glomerular filtration membrane, when the damage is severe, it will lead to high urine immunoglobulin G.
If you find high urine immunoglobulin G, you should go to the nephrology department of regular hospitals to get a clear picture of the cause of the disease and standardize the treatment according to the cause of the disease.
