What does microangiopathy primarily affect?

Microangiopathy primarily affects the smallest blood vessels in the body, which include capillaries, arterioles, and venules. This condition is characterized by damage to these microvessels, leading to various complications depending on the organ systems involved.

The consequences of microangiopathy can vary widely but often include reduced blood flow and oxygenation to tissues, which can result in ischemia, necrosis, and organ dysfunction. It is particularly relevant in conditions like diabetes mellitus and hypertension, where microvascular complications can lead to issues such as diabetic retinopathy, nephropathy, and neuropathy.

By focusing specifically on the smallest blood vessels, microangiopathy highlights the importance of vascular health at the micro-level, distinguishing it from conditions that impact larger blood vessels.
