Chronic Complications of Diabetes are the predictable downstream consequences of sustained hyperglycemia-driven microvascular and macrovascular injury. Retinopathy: fragile new vessel formation → vitreous hemorrhage, traction retinal detachment → blindness. Nurse screens annually (dilated fundus exam). Early: no symptoms — screening is the only protection. Nephropathy: glomerular sclerosis progresses from microalbuminuria → overt proteinuria → declining GFR → CKD → ESRD. Annual urine albumin/creatinine ratio, BP control, ACE inhibitor/ARB therapy per orders. Neuropathy: peripheral (burning/tingling/numbness in stocking-glove distribution), autonomic (gastroparesis, orthostatic hypotension, urinary retention, cardiac denervation), and focal. Foot exam every visit; daily foot inspection teaching. Macrovascular: CAD is the leading cause of death in T2 diabetes. PAD causes claudication and poor wound healing. Stroke risk is 2–4× increased. Boards test: annual complication screening schedules; Charcot foot recognition; non-healing wound as a referral trigger; and teaching that glucose control + blood pressure control + lipid management all independently reduce complication risk.
