Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder which is at present rapidly growing to an alarming epidemic level. Various pathogenic processes are involved in the development of diabetes mellitus. This spectrums from autoimmune destruction of pancreatic beta cells with consequent deficiency of insulin to abnormalities that lead to resistance to the action of insulin. In the 21st century, the astounding rise in obesity, poor diet, and inactive lifestyles have increased the prevalence dramatically. Although several therapies are in use, Western medications are associated with adverse drug reactions and high cost of treatment. Therefore, there is currently a growing interest in herbal medicines to replace or supplement the Western medications. Extensive research is essential to enhance diagnoses, treatment, and to lessen healthcare expenditures. This chapter provides an overview of the classification, diagnosis, symptoms, complications, and economic burden of diabetes mellitus. Additionally, the authors discuss the current and upcoming therapies to treat this metabolic disorder.
