Diabetes is dificult to manage, but we know that a person with diabetes needs to be educated, motivated, and diligent to succeed. Unfortunately, most people with diabetes do not enjoy a complete regimen of care, and don't know what they are missing.

Diabetes is marked by problems in controlling blood sugar. People with diabetes who test their sugar several times a day can manage their food intake, exercise, and medications to better control the sugar. This can reduce the impact on fine blood vessels, and thus prevent blindness, nerve damage (leading to injury and amputation), and kidney failure. But this regimen can be expensive and the person with diabetes needs medical, social, and emotional support. And this help is needed during the person's daily routines, and not solely in a medical care setting. As people age, they tend to have multiple chronic diseases and have greater difficulty affording their medications.
But people with diabetes are also at risk for heart disease and death; many don't know the importance of managing cholesterol, blood pressure, and not smoking as essential to prevent heart disease.
