In Episode 211 of the Fit Mother Project Podcast, I continue the Blind Spots<\/em> series with an organ most women never think about until something goes wrong:<\/p>\n

… The kidneys.<\/strong><\/p>\n

I start with one question. “When did your doctor last test your urine for protein?”<\/p>\n

For most women the answer is never, or not in years. Yet this cheap, simple test gives the earliest warning of kidney damage, and it gets missed all the time.<\/p>\n

I explain why your kidneys do far more than make urine.<\/strong><\/p>\n

They help control your blood pressure, tell your body to make red blood cells, activate vitamin D and keep your electrolytes in balance.<\/p>\n

I cover the lab markers to ask for at your next physical, including why women who lift weights or take creatine should ask about cystatin C<\/strong>.<\/p>\n

I also clear up common myths about protein and creatine and look at the link between your kidneys and your adrenal glands.<\/p>\n

I finish with a simple, food-first plan to protect your kidneys for decades to come.<\/p>\n

More than 1 in 7 adults have chronic kidney disease, and as many as 9 in 10 of them don’t know it.<\/strong><\/p>\n

If you’ve been blaming fatigue, poor sleep, swollen ankles or waking up at night to pee on age and stress, this episode will help you look a little deeper.<\/p>\n

Fit Mother Project Key Takeaways:<\/b><\/h2>\n
    \n
  • Your kidneys run more than you think.<\/strong> They filter 150\u2013180 liters of blood plasma a day. They also help regulate blood pressure, red blood cell production, active vitamin D and your electrolyte and pH balance.<\/li>\n
  • Kidney decline is silent.<\/strong> More than 1 in 7 adults have chronic kidney disease, and up to 90% don’t know it. Early signs like fatigue, poor sleep, swollen ankles, itchy skin and foamy urine are often blamed on age or stress.<\/li>\n
  • Ask for a urine albumin-to-creatinine ratio (UACR).<\/strong> It’s a cheap spot urine test that catches early kidney damage, but it’s rarely ordered, especially for people with high blood pressure.<\/li>\n
  • If you lift weights or take creatine, ask about cystatin C.<\/strong> Creatinine-based eGFR can make your kidneys look worse on paper than they are. Cystatin C isn’t affected by muscle mass or creatine.<\/li>\n
  • Blood pressure and blood sugar are the two biggest levers.<\/strong> Diabetes and high blood pressure cause about 2 out of 3 new cases of kidney failure. Protecting your metabolism protects your kidneys.<\/li>\n
  • Daily NSAID use adds up.<\/strong> Regular ibuprofen or naproxen for chronic back or knee pain reduces blood flow to the kidneys. Look for the root cause of the pain instead of masking it.<\/li>\n
  • Higher protein doesn’t damage healthy kidneys.<\/strong> A 2018 meta-analysis of 28 studies found no harm to kidney function in healthy adults. If you already have kidney disease, talk to your doctor about your protein intake.<\/li>\n
  • Your adrenal glands work closely with your kidneys.<\/strong> Morning sunlight helps regulate cortisol. If your blood pressure won’t come down even on medication, ask about screening for primary aldosteronism.<\/li>\n
  • To prevent kidney stones, drink more water and eat fewer processed foods.<\/strong> Excess sodium pulls calcium into the urine. Don’t cut dietary calcium. Aim for about 1,000 mg a day from food.<\/li>\n
  • A Fit Mother\u2013style plate protects your kidneys.<\/strong> Balance protein with potassium-rich produce, beans, nuts, olive oil and fish. Coffee and hibiscus tea may offer extra support.<\/li>\n<\/ul>\n
