Diabetes is a life-long chronic disease affecting more than 25.8 million people in the USA (8.3% of the population), and 7 million have undiagnosed diabetes. In 2010, approximately 1.9 new cases of diabetes were diagnosed among people between 20 years of age and older. In 2007, the direct and indirect medical cost for diabetes was $174 billion (CDC. n.d). By 2050, 1 in 3 adults in the USA will have diabetes. Diabetes is the leading cause of blindness, kidney failure, and amputations not related to accidents. Diabetics have shorter life expectancy and twice the risk of dying any day compared to a person of similar age-group without diabetes (CDC, n.d). Worldwide diabetic population increased by 133% in 30 years from 150 million to 350 million people, and by 2030, 552 million people could have the disease worldwide (MNT, 2011). There are 3 types of diabetes, Type1, Type2 and Gestational Diabetes.
