Understanding Kidney & Urinary Health
Your kidneys are filtration powerhouses - they filter 200 liters of blood daily, removing waste and balancing electrolytes. 37 million Americans have chronic kidney disease, often without knowing it. UTIs (urinary tract infections) affect 60% of women at some point. The good news? Prevention works! Hydration is #1 (2-3L water daily), cranberry prevents bacteria from sticking to bladder walls, D-mannose flushes out E. coli, and probiotics maintain healthy urinary flora. 🫘💊
