A disease that occurs due to high blood sugar levels is called diabetes. There are three major types of diabetes, namely, type 1 diabetes, type 2 diabetes, and gestational diabetes. Of these, the most prominent type of diabetes is the type 2 diabetes. In type 2 diabetes, the pancreas produces insulin but the body is not able to use the insulin, the way it should be used. This long-term condition causes high level of sugar circulating in the bloodstream that results in circulatory, nervous, and immune system disorders. The symptoms of type 2 diabetes are increased thirst, frequent urination, increased hunger, fatigue, blurred vision, frequent infections, etc. It is caused due to two interrelated problems. The first problem is insulin resistance developed by cells in muscle, fat and the liver which leads to lower amount of sugar. The second issue is the inability of the pancreas to produce enough insulin to manage blood sugar levels. Certain lifestyle changes such as eating healthy foods, losing weight, and avoiding inactivity for long periods are some measures to prevent or manage the disease. This book explores all the important aspects of type 2 diabetes and its medical management in the present day scenario. It will serve as a reference to a broad spectrum of readers.
