Mood Has a Biological Foundation
Mental health symptoms often reflect biochemical imbalances: cortisol dysregulation, nutrient deficiencies, inflammation, gut-brain axis disruption, and post-viral effects.
From a functional medicine standpoint, long standing emotional issues can be traced back to stress and cortisol. High stress situations, whether they be physical, mental/emotional, or dietary, can all all raise cortisol. Prolonged high cortisol diminishes DHEA, which is known as a "master hormone," as a precursor, it converts into both testosterone and estrogen, supporting energy and libido. Reduced DHEA levels are associated with major depressive disorders and increased risk of anxiety!
