Is adrenal fatigue real?

The adrenals sit atop the kidneys. They arise from two very different fetal layers and maintain different functional relationships throughout the organism. The adrenal medulla (in the center) is associated with the nervous system and secretes adrenaline that promotes the sympathetic response. The adrenal cortex (on the inside), is composed of lipids and secretes lipid hormones (steroids) that uphold parasympathetic functions. Within the parasympathetic, there are two opposing tracks, the pro-inflammatory and the anti-inflammatory, which control the inflammatory response, the basic mechanism the body uses to deal with stress and immune response. It includes hormones that influence the renal and reproductive spheres.
