IgA Nephropathy is a kidney disease that is also called Berger's disease. This condition causes inflammation in the kidneys and can eventually lead to kidney failure if not treated early. Synonyms for IgA Nephropathy include IgA glomerulonephritis, IgAN, and allergic nephritis. Other less common synonyms for this condition include mesangial IgA disease and Berger's syndrome. Early detection and treatment are essential for managing IgA Nephropathy, and patients with this condition are typically advised to make lifestyle changes such as following a healthy diet and reducing stress to prevent further damage to the kidneys.
