A growing number of individuals suffer from chronic fatigue, postural orthostatic tachycardia syndrome (POTS), and dysautonomia—often without clear answers or lasting relief. In his new book, The Hidden Epidemic: Subclinical Adrenal Insufficiency and the Fatigue Syndromes, John J. Herbert, DC, presents a compelling case that these seemingly distinct conditions may share a common, overlooked root cause.

Drawing on more than four decades of clinical experience, Dr. Herbert introduces the concept of subclinical adrenal insufficiency—a functional breakdown of adrenal regulation that does not appear on standard lab tests, yet profoundly impacts energy, resilience, and autonomic balance. The book explores how this hidden dysfunction may underlie chronic fatigue syndromes, POTS, dysautonomia, and related multisystem disorders.

Unlike conventional approaches that focus solely on symptom management, The Hidden Epidemic offers a broader, integrative framework that emphasizes early detection, lifestyle intervention, gentle movement, and nervous system restoration. The book is written for healthcare professionals, patients, and the general public alike, translating complex physiology into accessible, actionable insight. “Many patients are told their labs are ‘normal’ and are left without explanations for debilitating fatigue and autonomic symptoms,” says Dr. Herbert. “This book is about connecting the dots—and giving people a new lens through which to understand their health.”

Key topics covered in the book include:

· The adrenal–autonomic connection and its role in fatigue syndromes

· Why standard testing often misses subclinical adrenal dysfunction

· The relationship between stress physiology, POTS, and dysautonomia

· Gentle recovery strategies, including low-exertion movement and Qigong

· Practical guidance for patients and clinicians seeking root-cause solutions

As chronic fatigue–related conditions continue to rise, The Hidden Epidemic contributes a timely and provocative perspective to the ongoing conversation around integrative and preventive care.
