When your immune system accidentally attacks your kidneys, it can trigger IgA nephropathy, a kidney disease caused by the buildup of immunoglobulin A (IgA) in the filtering units of the kidneys. Also known as Berger's disease, it’s one of the most common causes of chronic kidney disease in young adults. This isn’t caused by infection or lifestyle alone—it’s an autoimmune glitch where your body makes too much IgA, and it clumps up in your kidneys, slowly damaging them over time.
Many people don’t know they have it until they notice blood in their urine after a cold or sore throat. That’s because IgA nephropathy often flares up after infections. Other signs include foamy urine from protein loss, swelling in the hands or feet, and high blood pressure. If left unchecked, it can lead to kidney failure. But not everyone progresses that far. Some live for decades with mild symptoms, especially if caught early. What matters most is monitoring kidney function, controlling blood pressure, and reducing protein in the urine—things your doctor can track with simple blood and urine tests.
The good news? You’re not powerless. Lifestyle changes like cutting back on salt, avoiding NSAIDs like ibuprofen, and quitting smoking can slow progression. Medications like ACE inhibitors or SGLT2 inhibitors are often used to protect kidney function. And while there’s no cure, research is moving fast—new drugs targeting IgA production are already in clinical trials. What you see in the posts below are real stories and guides on managing kidney health, from spotting early warning signs to understanding how drugs like mefenamic acid, a painkiller often used for menstrual cramps can interact with kidney function, or how medication safety, the practice of using drugs without causing harm becomes even more critical when your kidneys aren’t filtering properly. You’ll also find advice on avoiding kidney stress from common meds, understanding lab results, and making daily choices that support long-term kidney health.
Whether you’ve just been diagnosed or you’re helping someone who has, the information here isn’t about fear—it’s about control. You don’t need to know every detail of immunology to take smart steps. Just know your numbers, ask the right questions, and stick with what works. The posts below give you exactly that—clear, no-fluff guidance on what to do next.
Glomerulonephritis is an immune attack on the kidney's filtering units, causing protein or blood in urine, high blood pressure, and fatigue. Learn the types, treatments, and why early diagnosis matters.
