Insulin Resistance: Understanding the Origins
Insulin resistance is a prevalent health issue globally and understanding its origins is crucial. The podcast delves into two categories of causes: primary and secondary. Primary causes include inflammation, stress hormones like cortisol and epinephrine, and chronically elevated insulin levels. Inflammation, for instance, activates pathways in cells leading to decreased insulin response. Stress hormones push up glucose levels, increasing the demand on insulin, thus promoting insulin resistance. Chronically elevated insulin signals the body to grow, contributing to insulin resistance.
Inflammation as a Primary Cause of Insulin Resistance
Inflammation emerges as a significant driver of insulin resistance, affecting cells, rodents, and humans. The inflammatory pathways within cells, not necessarily immune responses, play a key role. Studies on animals and humans show that inducing an immune response leads to insulin resistance. Inflammatory markers like C-reactive protein impact insulin sensitivity, indicating the intricate link between inflammation and insulin resistance.
Stress Hormones and Their Role in Insulin Resistance
Stress hormones, including cortisol and epinephrine, contribute to insulin resistance by elevating blood glucose levels. Factors like sleep deprivation and excessive caffeine consumption can spike stress hormones, worsening insulin resistance. Research demonstrates that stress hormones drive the body towards insulin resistance, showcasing the impact of stress on metabolic health. Managing stress levels becomes crucial in combating insulin resistance.
Insulin Resistance and Fat Cells: A Critical Connection
Fat cells serve as a fundamental starting point for insulin resistance, preceding muscle or liver involvement. Hypertrophic fat cells, triggered by elevated insulin and sufficient energy, lead to insulin resistance. The process of fat cell growth, constrained by a limit, prompts insulin resistance to prevent further enlargement. Hypoxia-induced inflammatory responses in fat cells further contribute to the development of insulin resistance, underscoring the significance of fat cell dynamics in metabolic health.
