Final answer:
Diabetic complications can affect both microvascular and macrovascular systems in the body. Microvascular complications involve damage to the blood vessels in the eyes, kidneys, and nerves, while macrovascular complications increase the risk of coronary artery disease and stroke. These complications arise from high blood glucose levels in poorly controlled diabetes.
Step-by-step explanation:
Diabetic complications can affect both the small blood vessels (microvascular complications) and the large blood vessels (macrovascular complications). Microvascular complications include damage to the blood vessels in the eyes, kidneys, and nerves. For example, damage to the blood vessels in the retina of the eye can cause gradual vision loss and blindness. Macrovascular complications include an increased risk of coronary artery disease and stroke due to damage to the larger blood vessels. These complications can occur when diabetes is not well controlled and there are high blood levels of glucose.
