Diabetes is one of the most common chronic diseases. Most patients with type 2 diabetes are obese, and the global epidemic of obesity largely explains the dramatic increase in the incidence and prevalence of type 2 diabetes over the past 20 years. In the last decade intensive research has brought about an enormous change in the clinical approach to diabetes treatment. In this review we briefly discuss the main changes in diabetes treatment, such as new medications, bariatric surgeries and technology innovations. We hope that this short review would urge the reader to expand his knowledge on the subject.
