🔢 Target Kidney Lab Ranges

Serum Creatinine (Men): ~0.7–1.3 mg/dL
Serum Creatinine (Women): ~0.6–1.1 mg/dL
Blood Pressure (goal): under ~130/80 (per the 2017 threshold noted in the episode)

🔑 Key Takeaways

Top risks: Diabetes and hypertension; together they’re a “double whammy” on the kidneys.
Know your numbers: Creatinine in range; monitor BP throughout the day—often highest in the morning.
Morning spike: Cortisol rises around ~8am and can elevate blood pressure; caffeine can add 4–15 mmHg for 2–3 hours.
Med classes that can stress kidneys: Frequent NSAIDs, certain antibiotics (e.g., aminoglycosides), high-dose antivirals, PPIs, and contrast dye—work with your physician and hydrate well.
Stones: Calcium oxalate and uric acid are most common; hydration and diet patterns matter.

✅ Action Steps to Support Kidney Health

Lower blood pressure & blood sugar: Work with your doctor on the right medications and lifestyle plan.
Dial in nutrition: Beyond Keto / Keto Zone approach (lower sugar/processed carbs; Mediterranean-style whole foods).
Watch sodium & belly fat: Restaurant foods are salt-heavy; aim for ~1.5g sodium/day if advised by your provider.
Smart caffeine: Consider limiting to ~2 cups/day and re-check BP later in the visit/day.
Exercise that’s joint-friendly: Elliptical, cycling/recumbent bike, pool work.
