Vascular diseases refer 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, varicose veins, and aneurysms. Risk factors often include high blood pressure, high cholesterol, and diabetes. Symptoms of vascular diseases can vary widely, ranging from pain and swelling in the limbs to more severe issues like ulcers or gangrene. Early diagnosis and treatment are crucial to managing these conditions effectively. Lifestyle changes, medications, and sometimes surgery can help improve vascular health and prevent complications.
