Tilt Happens

Many people experience symptoms such as dizziness, fatigue, brain fog, palpitations, or near-fainting during everyday activities like standing, eating, or being in warm environments. These experiences are often confusing and frustrating, especially when routine medical tests appear normal. This book explains why those symptoms occur and how they can be understood through proper autonomic testing.

Tilt Happens is a rigorous, clearly written exploration of the autonomic nervous system and the diagnostic methods that reveal dysfunction when standard evaluations fall short. Written by a physician who both treats dysautonomia and lives with it, this book replaces vague explanations with measurable physiology, clear mechanisms, and practical interpretation.

Rather than focusing on symptoms alone, Tilt Happens explains how autonomic dysfunction behaves under real-world conditions and why testing matters more than reassurance. Readers are guided through heart rate variability (HRV), deep breathing, the Valsalva maneuver, standing and tilt testing, sudomotor evaluation, and integrated autonomic interpretation, learning how each test reveals specific patterns of autonomic regulation and failure.

The book clarifies why normal vital signs do not rule out dysautonomia, how autonomic dysfunction can remain hidden at rest yet emerge under physiologic stress, what testing patterns distinguish postural orthostatic tachycardia syndrome, orthostatic intolerance, neuropathic dysautonomia, and central autonomic disorders, and how medications can alter or mask autonomic findings.

Each chapter combines scientific explanation with practical interpretation, translating complex autonomic data into information that is meaningful for both clinicians and patients. Structured sections provide mechanism-based explanations, real-world translation, and clear guidance without oversimplifying the underlying physiology.

Tilt Happens is not a wellness guide, a symptom checklist, or a motivational narrative. It is a physiology-first examination of a system that governs circulation, temperature regulation, digestion, energy balance, and consciousness, yet is frequently overlooked in routine medical care.

For patients seeking clarity, clinicians seeking accuracy, and anyone wanting a deeper understanding of autonomic function, Tilt Happens offers a calm, evidence-based explanation of symptoms that are often misunderstood.

Dysautonomia is not mysterious. It is measurable. And with the right framework, it can be understood.
