The major cause of complications and death in diabetes is due to which type of vascular damage?

• A. Macrovascular damage
• B. Macrovascular and microvascular damage
• C. Neuromuscular damage
• D. Microvascular damage

Answer: (D)

Macrovascular damage is the main driver of death in diabetes. Diabetes accelerates atherosclerosis in large and medium arteries, making cardiovascular events like heart attack and stroke the leading cause of mortality. Microvascular damage, on the other hand, leads to major complications such as retinopathy, nephropathy, and neuropathy, which cause significant disability but are not the primary cause of death. So while microvascular complications are critical to manage, reducing macrovascular risk factors—blood pressure, lipid levels, smoking, and overall cardiovascular health—has the biggest impact on survival, with glycemic control mainly helping prevent microvascular problems.
