Simultaneous feelings of exhaustion and being “keyed up” characterize early adrenal dysfunction, the subject of nurse practitioner Marcelle Pick’s self-help book. The adrenal glands are responsible for providing the fight-or-flight hormones in response to stress. If they’re under-producing, that’s Addison’s disease, and if they’re overproducing, that’s Cushing’s syndrome. “But if your adrenal imbalance is less extreme — as is true for hundreds of thousands of U.S. women — your practitioner is unlikely to recognize your condition,” Pick writes. She suggests a 30-day plan to solve adrenal dysfunction, including dietary supplements, exercise, stress-reduction techniques and, the biggie, an adrenal-friendly diet with regular meal times and no processed foods.
