Vascular complications refer to issues that arise in the blood vessels, which can affect circulation and overall health. These complications can include conditions such as thrombosis, where blood clots form in veins or arteries, and aneurysms, which are bulges in blood vessel walls that can rupture. These complications can lead to serious health problems, including stroke or heart attack, if not addressed promptly. Risk factors include diabetes, hypertension, and high cholesterol, which can damage blood vessels over time. Early detection and management are crucial for preventing severe outcomes.
