Diabetes refers to a type of metabolic disorder characterized by a persistently high blood sugar level. It occurs as a result of inflammation in an intricate immunological process. Insulin resistance is caused by inhibition of insulin signaling which triggers a sequence of immune responses that aggravate the inflammatory state and leads to hyperglycemia. The common symptoms of diabetes are increased appetite, frequent urination and increased thirst. It is classified into three types, namely, gestational diabetes, type 1 diabetes and type 2 diabetes. The diagnosis of diabetes can be done through blood tests to measure the amount of glucose level in the blood. Diabetes management focuses on maintaining blood sugar levels as close to normal, while avoiding hypoglycemia. This can be usually achieved through weight loss, dietary changes, usage of appropriate medications and exercise. This book is compiled in such a manner, that it will provide in-depth knowledge about the molecular, cellular and clinical immunology of diabetes. Its extensive content provides the readers with a thorough understanding of the condition.
