You've just been told you have autoimmune glomerulonephritis, and now your brain is doing that thing where it keeps replaying the words while the doctor's mouth keeps moving. This guide is for you. It's written in plain language, with zero condescension and zero panic. You'll learn what's actually happening inside your kidneys — why your immune system is attacking your own filter units like they're the enemy — and what that means for your body day to day. No jargon without explanation, no false hope, no doom-and-gloom. Just clear, practical information from the perspective of a friend who happens to know a lot about medicine.
