Glomerular injury may have proteinuria, hematuria, edema and other manifestations in the early stage.
1. Proteinuria: Normal glomerular filtration membrane only allows small molecules of protein to pass through, and the protein filtered through the glomerulus can be reabsorbed by the proximal tubule, so the protein in urine is extremely low. So when the glomerulus is damaged, proteinuria may appear in the urine.
2. Hematuria: When glomerular damage is severe, such as crescent formation, glomerular basement membrane rupture, etc., red blood cells will enter the urine and form hematuria.
3. Edema: Decreased glomerular filtration rate can easily cause water and sodium retention, which in turn causes edema.
Glomerular injury may also appear other symptoms, it is recommended that patients go to regular hospitals in a timely manner, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
