In this timely book, Steven Phillips, MD, and his former patient, Sony singer-songwriter Dana Parish, reveal striking evidence that a broad range of common infections, from COVID-19 to Lyme and many others, cause a variety of autoimmune, psychiatric, and chronic conditions. Chronic explores the science behind what makes them difficult to diagnose and treat, debunks widely held beliefs by doctors and patients alike, and provides solutions that empower sufferers to reclaim their lives. Dr. Phillips was already an internationally renowned physician specializing in complex, chronic diseases when he became a patient himself. After nearly dying from his own mystery illness, he experienced firsthand the medical community's ignorance about the pathogens that underlie a deep spectrum of serious conditions-from fibromyalgia, multiple sclerosis, chronic fatigue syndrome, rheumatoid arthritis, and lupus, to depression, anxiety, OCD and neurodegenerative disorders. Parish, too, watched her health spiral after twelve top doctors missed an underlying infection that caused heart failure and other sudden debilitating physical and psychiatric symptoms. Now, they've come together with a mission: to change the current model of simply treating symptoms-often with dangerous, lifelong drugs-and shift the focus to finding and curing root causes of chronic diseases that affect millions around the world.
