@naturehackstv: Most kidney infections don't start in the kidney. They start downstairs — and climb. Bacteria from the gut slip into the urinary tract and multiply inside the bladder. Urine should flush them back down… but some cling on — and climb the ureter, against the current, until they reach the kidney itself. Inside, they spread through its soft tissue. Your immune system floods in — and the whole kidney swells with the battle. That battle is the fever. That battle is the deep ache in your back. And unlike a bladder infection, this one sits one step away from your bloodstream. A kidney infection is a bladder infection that climbed too far. The fight was never meant to reach here. Next episode — the series finale: kidneys that fill with balloons of fluid 👀 Educational content only — not medical advice. Did you know kidney infections start in the bladder? 👇 #kidneyinfection #pyelonephritis #kidneyseries #kidneydisease #kidneys
