Diabetics Spend $4,100 More Than Non- Diabetics

In the first study to examine medical cost increases for individuals living with diabetes on a year-by-year basis, researchers at RTI International, an independent, nonprofit research institute based in North Carolina, calculated that a 50-year-old newly diagnosed with diabetes spends $4,174 more on medical care per year than a person the same age who doesn't have diabetes. For the person with diabetes, medical costs go up an additional $158 per year every year thereafter, over and above the amount they would increase due to aging-related increases in medical expenses.

Most of the increase can be attributed to the cost of diabetes-related complications, such as heart and kidney disease, the researchers found. Once they controlled for complications, the remaining annual increase in medical costs was $75 per year -- the bulk of which could be attributed to the increasing need for diabetes medications the longer a person lives with the disease.

"The good news is that many of these costs could be contained through proper diabetes management and lifestyle changes," said lead researcher Justin Trogdon, Research Economist. "Numerous studies show that losing weight and increasing physical activity, along with maintaining proper blood glucose levels, can substantially delay or reduce the risk for diabetes-related complications. What our study does is to point out that there is also a cumulative, financial impact to the progression of this disease."

Preventing the onset of diabetes would also help to reduce cumulative costs, since medical expenditures grow along with the duration of the disease, the researchers concluded. "Delaying the development of diabetes will delay the steady rise in medical expenditures that accompanies it," they wrote.
