Most people don’t die suddenly. They decline for decades—then arrive in the ICU when it’s too late.
Before the Alarm is about what happens before that moment. It challenges the belief that you can fix your health later—with medications, procedures, or the latest biohacks.
You can’t.
Drawing from years in critical care medicine, Dr. M.K. Jarbou reveals a hard truth: The diseases that end lives—heart disease, cancer, metabolic syndrome, and frailty—are built quietly over time. And they are often preventable.
This book is a practical guide to longevity, health span, and preventive medicine. Inside, you’ll learn:
The strongest predictors of survival
How muscle loss and aging increase the risk of hospitalization and death
The hidden role of sleep and circadian rhythm in chronic disease
When hormone replacement therapy is useful
The truth about GLP-1 medications, peptides, and biohacking trends
How to build physiologic reserve using The Reserve System—a science-based framework for longevity
Longevity isn’t built at the end of life. It’s the foundation you’ve built over the course of life that determines the reserve your body holds on to. There are aspects of longevity that might surprise you—and that have long been neglected by science.
Longevity is built before the alarm goes off—and this book shows you how to act before it’s too late.
M.K. Jarbou, MD, is a board-certified physician in pulmonary, sleep, and critical care medicine, and Pulmonary Medical Director at SSM Health St. Mary’s Hospital in Jefferson City, Missouri. He is also board-certified in anti-aging and regenerative medicine (ABAARM) and co-founder of The Longevity Clinic.
Over more than two decades treating patients in the ICU, he saw the same pattern again and again: by the time a patient’s body finally forced the issue, the real story had usually begun years earlier — long before any symptom demanded attention. That observation became the Reserve System, a framework for understanding why health declines long before illness becomes visible.
Before the Alarm: What the ICU Reveals About Real Longevity is Book One in the Reserve System series, and lays out the equation at its center: Reserve = (Capacity × Quality) − Load.
Dr. Jarbou continues to practice at The Longevity Clinic, where he leads the clinical program.
