Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
A lot of doctors report factor V Leiden tests as positive or negative, but you should get a copy of the test report. I had a PE a couple of months ago and they originally told me I was factor V Leiden negative. On further inspection, I saw that I actually was a heterozygous factor V Leiden mutant.
So everyone has two copies of every gene. You probably remember recessive and dominant genes. Well, one copy might have a mutation but it is recessive because the other copy is dominant and gets expressed.
For factor V Leiden it is not so simple. Both copies of the gene are active. If you are unfortunate and have the Leiden mutation on both genes, you are going to have real major problems with clots. However, if you have the mutation on one gene only (heterozygous), then you are still going to have problems because that gene is still busy creating clotting factor v that is impervious to regulation by protein c. Sorry to be so technical, but the bottom line is that you still have too much clotting factor in your blood if you are a heterozygous Leiden mutant.
So you need to find out if your daughter is heterozygous, because if she is, she will need to stay off the birth control pills. Heterozygous Factor V mutation increases the risks of getting a clot by 5-7 times and that risk factor goes up even higher when you add in birth control pills.
Sorry to hear about your troubles, and I hope the best for you and your daughter.
Her doctor (gyn) is who took her off her bc pills. Our daughter was not happy becuase this was the only way to regulate her cycle. She's been off for a few months now and some months she has her cycle and others she does not. I personally did not want her to take them with the history I created for her. But I knew she needed to regulate her cycles ~ although now I read it is fine not to have a cycle each month.
