Yaz and Yasmin cause blood clots. When a blood clot finds its way to the lungs, the result is a pulmonary embolism. The blood clot cuts off the flow of oxygen and blood to a portion of the lung. A pulmonary embolism can be fatal. In fact, about 15% of all sudden death is attributable to pulmonary embolisms. In some cases the pulmonary embolism can travel to the brain and cause a stroke. In less severe cases it can lead to lung damage. The symptoms of a pulmonary embolism include:
- Sudden shortness of breath, especially after even slight exertion;
- Rapid breathing;
- Coughing up blood;
- Chest pain that mimics a heart attack. The pain gets worse with exercise but remains even after resting; and
- Rapid heartbeat.
