A wide range of problems can affect your blood vessels, including: 1. Aneurysm, a bulge in a weak or damaged portion of an artery. Aneurysms can occur anywhere in your body. If they rupture (break open), they may cause life-threatening internal bleeding. 2. Arterial diseases, including coronary artery disease, carotid artery disease and peripheral ...
Some blood vessel disorders are very common. For example, nearly half of all adults in the U.S. have high blood pressure. But others, such as vascular malformations, are rare. Less than 1% of the population develops this condition.
Your risk for vascular diseaseincreases if you: 1. Are older than 65. 2. Have overweight/obesity. 3. Have diabetes or high cholesterol. 4. Smoke. 5. Don’t exercise. 6. Have an illness that damages your blood vessels. 7. Have a family history of vascular disorders.
Symptoms vary widely across the different types of blood vessel disorders. Some, such as aneurysms or vascular malformations, may not cause symptoms until a serious problem develops. In general, it’s a good idea to talk to your doctor if you experience: 1. Changes in skin color, such as a bluish skin tone. 2. Coldness or numbnessin your legs, feet,...
Your healthcare provider may use a variety of tests to diagnose problems in your blood vessels, including: 1. Electrocardiography. 2. Ultrasound. 3. Echocardiography. 4. Exercise stress test. 5. CT scan. 6. MRI. 7. Angiography. 8. Cardiac catheterization. 9. Tilt table test.
Treatment for blood vessel disorders may include: 1. Lifestyle changes: You can reduce your risk of blood vessel disorders by not smoking, reducing your alcohol consumption, maintaining a healthy body weightand avoiding unhealthy food. 2. Medication: Some people need medication to manage their blood pressure, reduce their risk of blood clots or low...
