Core tip: The prevalence of diabetes mellitus (DM) and pre-diabetes in old age is very high. However, clinical guidelines do not provide complete information to the clinician managing patients with these conditions. Pre-diabetes status in the elderly increases the risk for DM, but probably does not increase the risk of cardiovascular morbidity and mortality. The role of therapeutic interventions in elderly patients with pre-diabetes is not yet proven. New-onset DM in older age is associated with better glycemic control and better prognosis compared to long standing DM in this population. Nevertheless, higher glucose levels in elderly with new-onset DM are associated with increased all-cause mortality. The benefits of tight glycemic control in elderly with long standing DM are doubtful and may cause more harm than good. To conclude, more research in this field is needed. Currently, the clinical approach for DM and pre-diabetes in the elderly should be tailored to meet individual needs.
