What Causes Blood Clots?
4. Blood Clots and Chronic Diseases
Some chronic diseases increase the risk of developing blood clots inside the blood vessels. Cancers are among the most common causes of blood clots. Patients with cancer are usually older and less active physically. This is why they have a higher risk of blood clots. Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, also pose a risk for the formation of blood clots.
The most common theory is that inflammation causes injuries in blood vessels. Inherited clotting disorders such as sickle cell anemia cause thickening of the blood, which increases the risk of developing blood clots. Infections and autoimmune diseases also increase the risk of forming blood clots. However, the exact mechanism is not clear.
