Vascular disease refers to a group of conditions that affect the blood vessels, including arteries and veins. These diseases can lead to problems such as reduced blood flow, blood clots, and even heart attacks. Common types include peripheral artery disease, venous insufficiency, and aneurysms. Risk factors for vascular disease include high blood pressure, high cholesterol, smoking, and diabetes. Symptoms may vary but can include pain, swelling, or changes in skin color. Early detection and management are crucial to prevent serious complications and improve overall health.
