A Metabolic
– Hypoglycemia– Ketoacidosis– Hyperosmolar coma– Lactic acidosis
B Infections
C Vascular complications
Vascular complications of diabetes
Microangiopathic.Retinopathy.Nephropathy.Neuropathy
Macroangiopathic.Coronary artery disease.Cerebro-vascular disease.Peripheral vasc. disease
Peripheral vascular disease in diabetics differs from that in non-diabetics
Diabetic Non-diabetics
Frequency More common Less common
Age of onset Younger age Older age
Clinical course Rapid Less Rapid
Occlusion Multisegmental Single segment
Lower limbs Both Unilateral
Vessels involved
Proximal & distal
