Deep Vein Thrombosis Overview
Deep venous thrombosis (DVT) refers to a blood clot embedded in one of the major deep veins of the lower legs, thighs, or pelvis. A clot blocks blood circulation through these veins, which carry blood from the lower body back to the heart. The blockage can cause pain, swelling, or warmth in the affected leg.
Blood clots in the veins can cause inflammation (irritation) called thrombophlebitis. Severe complications of deep vein thrombosis occur when a clot breaks loose (or embolizes) and travels through the bloodstream, causing blockage of blood vessels (pulmonary arteries) in the lung. Called pulmonary embolism, this can lead to severe difficulty in breathing and even death, depending on the degree of blockage.
In the United States, about 2 million people per year develop deep vein thrombosis. Most of them are aged 40 years or older. Up to 600,000 are hospitalized each year for the condition.
Deep vein thrombosis can lead to a more serious complication, blood clots in the lung (pulmonary embolism). Statistics reveal that at least 650,000 patients die each year from pulmonary embolism, making it the third most common cause of death in the United States.

Birth Control Medications (Contraceptives) »
Birth Control Medications Introduction
Birth control (contraceptive) medications contain hormones (estrogen and progesterone, or progesterone alone). The medications are available in various forms, such as pills, injections (into a muscle), topical (skin) patches, and slow-release systems (vaginal rings, skin implants, and contraceptive-infused intrauterine devices [Mirena]).
Choosing which estrogen and progesterone dose, type, and administration method is highly patient specific, meaning that the choice greatly depends on factors unique to an individual. General goals are to choose a product that provides good menstrual cycle control with the fewest adverse (side) effects and to use the lowest hormone dose possible. After beginning birth control medications, it may be necessary to adjust the dose or to choose a different product.
The estrogens and progesterones contained in birth control medications available in the United States include the following:
