Diabetes mellitus Type 1 or Type 1 diabetes is a type of diabetes mellitus, which is caused by little or no production of insulin by the pancreas. This leads to high blood sugar levels in the body. Such a high blood sugar level is typically an autoimmune response involving a loss of insulin-producing beta cells in the pancreas. Diabetes mellitus Type 2 or Type 2 diabetes is a metabolic disorder caused due to insulin resistance, high sugar levels in blood and comparatively low insulin production. It is the most common form of diabetes and makes up nearly 90% of all cases of diabetes. Genetics and lifestyle are the major contributing factors for the incidence of Type 1 and Type 2 diabetes. Symptoms for both these disorders are similar. These include weight loss, frequent urination, increased thirst and hunger, etc. This book provides comprehensive insights into Type 1 and Type 2 diabetes. It discusses the fundamentals as well as modern approaches in the management of these disorders. For all those who are interested in endocrinology and metabolism, this book can prove to be an essential guide.
