Proteinuria is the presence of an abnormal amount of protein in the urine, indicating a potential problem with kidney function. Under normal circumstances, kidneys filter waste products from the blood while retaining essential proteins. However, when the kidneys' filtering units (glomeruli) are damaged, proteins can leak into the urine.
The outlook for proteinuria depends on its underlying cause and the promptness of treatment. Early detection and management of the underlying condition can prevent progression to chronic kidney disease or end-stage renal disease. Regular monitoring and follow-up with a healthcare provider are essential for managing proteinuria and maintaining kidney health.
