Imagine starting each day feeling a little more tired than usual. You pretend it’s nothing: maybe it’s just another hectic week. But what if that persistent fatigue is a subtle warning sign from your kidneys?

According to the National Kidney Foundation, more than 37 million American adults have chronic kidney disease (CKD). Yet, 90% of them don’t know it until it’s advanced, when treatment options are limited. Your kidneys silently filter toxins, balance fluids, and maintain stable electrolyte levels. When they weaken, the signs are often so subtle that they’re mistaken for common health problems.
