The Complete Long COVID Handbook

The Complete Long COVID Handbook, Volume 2: Dysautonomia By Dr. Robert Groysman, MD A roadmap to one of Long COVID's most overlooked root causes. Millions are living with lingering symptoms after COVID-debilitating fatigue, brain fog, dizziness, palpitations, gut issues, sleep problems, and strange neurological sensations. At the center of these struggles lies dysautonomia , a malfunction of the autonomic nervous system that controls heart rate, digestion, temperature, and more. In this groundbreaking volume, Dr. Robert Groysman-board-certified anesthesiologist, pain medicine specialist, and pioneer in Long COVID care-explains how dysautonomia fuels persistent symptoms and, most importantly, how to treat it. Inside, you'll discover: Clear explanations of how the autonomic nervous system works-and what happens when it's stuck in "fight or flight." Practical tools to recognize, test for, and monitor dysautonomia, including HRV and COMPASS-31. Therapies that restore balance: Stellate Ganglion Block (SGB) Vagus Nerve Stimulation (tVNS) Epipharyngeal Abrasive Therapy (EAT) Medications, supplements, and breathing protocols How stress, inflammation, and poor sleep worsen symptoms-and strategies to reset the system. Real patient stories that highlight recovery, setbacks, and hope. More than symptom management Dr. Groysman connects dysautonomia to conditions such as POTS, MCAS, ME/CFS, and neuropathies , showing how these fit into the larger Long COVID puzzle.

The Complete Long COVID Handbook, Volume 4: Gut Dysbiosis By Dr. Robert Groysman, MD Long COVID continues to impact millions worldwide, leaving patients with persistent fatigue, brain fog, digestive problems, food intolerances, and systemic inflammation that refuses to resolve. One of the most overlooked yet powerful drivers of these lingering symptoms is the gut. In this groundbreaking fourth volume of The Complete Long COVID Handbook series, Dr. Robert Groysman, a physician and global Long COVID specialist, unpacks the science of post-viral gut dysbiosis. Inside, you'll discover: How COVID-19 disrupts the microbiome and damages the intestinal lining. Why conditions such as SIBO, candida overgrowth, and histamine intolerance frequently follow infection. The role of the gut-organ axis in Long COVID: how microbiome imbalance affects digestion, brain clarity, mood, hormones, immunity, the lungs, heart, and more. How dysbiosis drives systemic inflammation, worsens autoimmune conditions, and contributes to fatigue, anxiety, pain, and even skin disorders. Diagnostic tools-including stool tests, breath tests, and microbiome mapping-plus how to interpret results. Evidence-based strategies for healing: Prebiotics, probiotics, and postbiotics that nourish beneficial bacteria and restore balance. Dietary supports such as fibers, polyphenols, and fermented foods. Advanced therapies including peptides (BPC-157, KPV), colostrum, butyrate, and fecal microbiota transplantation (FMT). Whether you are a patient, or clinician, The Complete Long COVID Handbook: Gut Dysbiosis provides clarity and direction.

The Long COVID Handbook, Volume 7: Hormone Imbalance and Metabolic Disruption Persistent fatigue, brain fog, irregular cycles, or unexpected menopausal symptoms after COVID can be signs of a deeper hormonal disruption. Long COVID is known to affect the endocrine system, leading to thyroid, adrenal, and metabolic imbalances that leave many people looking for answers. In this volume, Dr. Robert Groysman explains how post-viral inflammation interferes with key hormones such as estrogen, progesterone, thyroid, cortisol, and insulin. You'll discover how these changes drive symptoms like exhaustion, mood swings, and weight fluctuations. The book outlines why conventional care often falls short and offers a step-by-step framework for restoring balance through targeted hormone support and metabolic healing. Readers will learn how to evaluate their thyroid and adrenal function, explore safer approaches to hormone replacement, and support recovery through improved sleep, nutrition, and stress regulation. Each chapter includes practical strategies and testing guidance that can be shared with a healthcare provider to personalize treatment. Written for those experiencing post-COVID fatigue, menstrual disruption, or metabolic changes, this handbook empowers readers to understand their symptoms and take informed action.

The Complete Long COVID Handbook: Volume 3 Mitochondrial Dysfunction By Dr. Robert Groysman, MD Millions struggling with Long COVID share the same hidden problem: their cellular power plants, the mitochondria, aren't working properly. When mitochondria falter, energy crashes, brain fog sets in, muscles weaken, and recovery feels impossible. In this accessible and hopeful guide, pain specialist and Long COVID expert Dr. Robert Groysman explains how mitochondrial dysfunction lies at the core of many lingering symptoms. Using plain language, real-world analogies, and practical tools, he helps readers understand: - How COVID-19 hijacks mitochondria and triggers lasting fatigue, brain fog, and pain - The role of oxidative stress, mitophagy (cellular cleanup), and methylation in recovery - Everyday signs that your mitochondria are struggling-even when lab tests look "normal" - Key diagnostic tools like the Organic Acids Test, lactate/pyruvate testing, and metabolic markers - Evidence-based strategies to restore cellular energy, from antioxidants and nutrients to advanced therapies like low-dose naltrexone, metformin, and red light therapy This volume is part of The Complete Long COVID Handbook series, which explores the six major mechanisms behind persistent symptoms: dysautonomia, mitochondrial dysfunction, gut dysbiosis, histamine excess/MCAS, endothelial dysfunction with microclots, and hormone imbalance. If you've been told "everything looks normal" but you still feel exhausted, foggy, or unable to bounce back after COVID, this book will help you finally connect the dots and take actionable steps toward healing. Your body isn't broken. With the right knowledge and tools, recovery is possible.

The Complete Long COVID Handbook: Endothelial Dysfunction & Microclots Volume 6 of the Series by Robert Groysman, MD Why does Long COVID make you feel so exhausted, foggy, short of breath-or worse-even when your tests look normal? One of the most overlooked causes may be hiding in your blood. New research reveals that many Long COVID symptoms may be driven by endothelial dysfunction (damage to blood vessel linings) and microclots (tiny, persistent clots that block oxygen flow). These invisible issues can affect your brain, muscles, nerves, and organs-leaving you sick, frustrated, and without answers. In this groundbreaking and easy-to-understand guide, physician Dr. Robert Groysman walks you through: What endothelial dysfunction and microclots are-and how they may be driving your symptoms Which tests can uncover these problems (even when basic labs look fine) What symptoms suggest your circulation is impaired Natural and medical treatment options, from supplements to apheresis What to expect with recovery, and how to track your progress This book is written for patients, families, and healthcare providers who want real explanations, practical tools, and a hopeful path forward. Whether you're newly diagnosed, stuck in a cycle of confusing symptoms, or searching for better care-this book helps you connect the dots and reclaim control. You're not imagining it. You're not alone. And you're not without options.

The Complete Long COVID Handbook: MCAS and Histamine Volume 5 of the Series by Robert Groysman, MD Is Long COVID making your body feel like it's reacting to everything? For many survivors, recovery from COVID-19 never feels complete. New food sensitivities, rashes, dizziness, brain fog, palpitations, gut upset, or crushing fatigue appear-often without warning. Standard tests come back "normal," yet life feels anything but. The hidden culprit? Overactive mast cells and excess histamine. In Overcoming Long COVID: Mast Cell Activation and Histamine, Dr. Robert Groysman, MD-an anesthesiologist and Long COVID specialist-explains how mast cells, the body's "first responders," can become hypersensitive after COVID. Once helpful, they begin flooding the body with histamine and other chemicals, triggering chaos across multiple systems. This book demystifies Mast Cell Activation Syndrome (MCAS) and histamine intolerance in clear, patient-friendly language. You'll discover: Why Long COVID triggers mast cell dysfunction-and how it differs from classic allergies Common symptoms and hidden triggers-from food and hormones to stress and environment Practical diagnostic insights-how to recognize MCAS even when labs look normal Step-by-step strategies-including medications, supplements, low-histamine diets, gut healing, and nervous system support Tools for daily life-how to manage flares, expand food tolerance, travel, and talk to family and doctors With science-based explanations and real-world clinical experience, Dr. Groysman offers hope and a roadmap for stabilizing mast cells, calming histamine overload, and reclaiming your quality of life. If you've been dismissed, told "it's just anxiety," or left searching for answers, this guide will help you connect the dots-and take back control, one step at a time.
