Vascular Diseases—Bleeding Disorders

Also called: Clotting disorders

Normally, if you get hurt, your body forms a blood clot to stop the bleeding. For blood to clot, your body needs cells called platelets and proteins known as clotting factors. If you have a bleeding disorder, you either do not have enough platelets or clotting factors or they don’t work the way they should.

Bleeding disorders can be the result of other diseases, such as severe liver disease or a lack of vitamin K. They can also be inherited. Hemophilia is an inherited bleeding disorder. Bleeding disorders can also be a side effect of medicines such as blood thinners.

Various blood tests can check for a bleeding disorder. You will also have a physical exam and history. Treatments depend on the cause. They may include medicines and transfusions of blood, platelets, or clotting factor.

The vascular system is the body’s network of blood vessels. It includes the arteries, veins and capillaries that carry blood to and from the heart. Problems of the vascular system are common and can be serious. Arteries can become thick and stiff, a problem called atherosclerosis. Blood clots can clog vessels and block blood flow to the heart or brain. Weakened blood vessels can burst, causing bleeding inside the body.

You are more likely to have vascular disease as you get older. Other factors that make vascular disease more likely include

• Family history of vascular or heart diseases
• Pregnancy
• Illness or injury
• Long periods of sitting or standing still
• Any condition that affects the heart and blood vessels, such as diabetes or high cholesterol
• Smoking
• Obesity

Losing weight, eating healthy foods, being active and not smoking can help vascular disease. Other treatments include medicines and surgery.
