This book is a collection of fourteen articles/chapters addressing 15 common health disorders (Chapter 14 addresses 2 types of syndromes). Some of these are also classified as chronic, inflammatory and/or autoimmune in nature. These illnesses may have symptoms in-common with others that can manifest similarly and so a general understanding of them can help to distinguish them from other health disorders. In addition to information regarding symptoms, I have also included general aspects regarding diagnoses and treatments. It is my hope that the information contained within the chapters is both informative and interesting for the reader. At the same time, it should be understood that proper diagnosis and treatment for any disorder affecting one's health, should be obtained through a medical professional. This book is not intended to be an extensive manual but is intended to contain information most often sought by laypersons on the subjects. {The eBook version of this book (identical in content) was passed through the Amazon KDP Platform's word check and was found to have no spelling errors. Each chapter also appeared previously as an article on Suite101, which has strict editorial guidelines regarding grammar.} CONTENTS CHAPTER ONE: The Diagnosis and Treatment of Celiac Disease CHAPTER TWO: Diagnosing and Treating Sjogren's Syndrome CHAPTER THREE: Diagnosing and Treating Pernicious Anemia CHAPTER FOUR: Acid Reflux and Lung Disorders CHAPTER FIVE: Rheumatoid Arthritis Basic Facts CHAPTER SIX: Metabolic Syndrome Basic Facts CHAPTER SEVEN: Systemic Lupus Erythematosus Basic Facts CHAPTER EIGHT: Non-Alcoholic Fatty Liver Disease and NASH CHAPTER NINE: Thyroid Autoimmunity CHAPTER TEN: Osteoarthritis CHAPTER ELEVEN: Adrenal Insufficiency Basic Facts CHAPTER TWELVE: A Quick Look at Adrenal Fatigue CHAPTER THIRTEEN: Mitral Valve Prolapse the Common Heart Murmur CHAPTER FOURTEEN: CFS and Fibromyalgia - The Syndromes of Fatigue and Muscle Pain
