What are the risk factors for phlebitis?
• One of the common risk factors for phlebitis is a trauma. For example, a trauma or an injury to the arm or leg can cause an injury the underlying vein resulting in inflammation or phlebitis. • Prolonged immobility is another common risk factor for phlebitis. Blood that is stored in the veins of the lower extremities normally is pumped toward the heart by the contraction of the lower leg muscles. If the muscle contraction is limited due to prolonged (hours) immobility by sitting on a plane or a car, the blood in the veins can become stagnant and clot formation can result in thrombophlebitis. • Hormone therapy (HT), birth control pills, and pregnancy all increase the risk for developing thrombophlebitis. • Cigarette smoking is another risk factor for thrombophlebitis. Smoking in combination with birth control pills can substantially increase the risk of thromboembolism. • Obesity is also a risk factor for thrombophlebitis. • Certain cancers are known to increase the risk of clot format
