Understanding insulin and chronic kidney disease is essential for protecting long-term kidney health. While most people associate insulin only with blood sugar and diabetes, few realise how insulin resistance, metabolic dysfunction, and hormonal imbalance can directly influence kidney function and drive the progression of chronic kidney disease (CKD).
In this video, Lindsey Zirker explains the crucial role of insulin in the body, the differences between Type 1 and Type 2 diabetes, and how cortisol and insulin interact to shape metabolic balance. She also breaks down the connection between insulin resistance and kidney disease, and why improving insulin sensitivity is key for supporting kidney health and preventing CKD progression.
You’ll learn how insulin resistance contributes to chronic kidney disease, which lab markers to monitor, and practical strategies to maintain healthy blood sugar levels while protecting kidney function. We also explore lifestyle approaches that support metabolic health, reduce inflammation, and lower the risk of kidney damage linked to insulin dysfunction.
If you’re looking to improve kidney health, balance insulin naturally, and better understand the metabolic drivers behind chronic kidney disease, this video provides essential insights and actionable steps.
