The necessary evolution of diabetes fellowships in the United States.

The number of Americans affected by diabetes continues to increase but the number of endocrinologists with specialty training to treat this population has not kept up with demand. Primary care outpatient visits can also not meet the projected diabetes population demands or the needs for other complex diabetes management issues. Treatments for diabetes including both medications and technologies continue to expand and become more complex. In response to these challenges there have been primary care physicians seeking specialized training to become diabetologists. This can fill some of the gaps left by a lack of resources in the U.S. healthcare system.
