More and more people are being diagnosed with diabetes and other hormone conditions and that is making a problem become obvious; there aren't going to be enough endocrinologists.
Endocrinologists are specially trained physicians who diagnose diseases related to the glands. They specialize in treating diabetes, obesity, osteoporosis, thyroid disorders, adrenal diseases, and a variety of other conditions related to hormones. But in America of the future, as the government gradually takes over health care, salaries for doctors are going down, not up, so it is not going to be easy to convince specialists to spend the time. A great doctor in the US Army makes the same money as an average supply officer of the same rank and time.
