Explore the early stages of IgA nephropathy, a kidney disease that often goes unnoticed until lab tests reveal abnormalities like protein or red blood cells in urine, or high creatinine levels. This video shows how some patients can develop nephrotic syndrome, leading to body swelling and potential kidney failure. Diagnosis typically occurs through a kidney biopsy, as IgA nephropathy cannot be detected by blood tests or scans alone. Learn about the symptoms, progression, and crucial diagnostic steps for IgA nephropathy in this informative session.
