Early detection of type 2 diabetes: the role of the community nurse.

Recent changes to the diagnostic criteria for type 2 diabetes have raised concerns that if steps are not taken to address relevant issues, the number of diagnosed sufferers will escalate in future years, with a similar increase in the prevalence of associated complications. Research suggests that for many patients, complications are evident at the time of diagnosis, and may have been present for several years before a diagnosis was made. Late presentation is the cause of considerable morbidity and mortality among these patients, largely because undiagnosed complications are often irreversible by the time the underlying diabetes is discovered. The current emphasis on public health augments the need for community nurses to recognize warning signs, particularly in patients who are at an increased risk of developing diabetes. This article aims to raise awareness of early signs and symptoms, and gives a brief insight into some of the associated health problems. If community nurses are to play a significant role in reducing the potentially devastating effects of this disease, they will need to be involved tin educating patients and implementing screening and intervention programmes.
