As someone who has PCOS, have you heard of thrombophilia or thrombosis? Possibly your doctor mentioned it? Thrombophilia is a condition where the blood has an increased tendency to form clots. A thrombosis is a blood clot in your blood circulation system.
If a blood clot in your blood gets loose, it could travel to a critical location and block the blood supply to your lungs, (pulmonary embolism), brain (stroke), heart (heart attack), or somewhere else.
One type of blood clot is called a venous thromboembolism, which is a is a clot in a deep vein, usually in the leg. There is some evidence that women with polycystic ovary syndrome have an increased risk of venous thromboembolsim.
As we go about our lives, the last thing we think about is blood clots. After all, that's a problem only for old people…or is it?
Quite a number of medical studies are suggesting that women with PCOS are more likely to have thrombophilia than other women. Also, abnormal blood clotting may be a factor in miscarriages among PCOS women.
The blood clotting system is very complex, and in the case of PCOS, several aspects of the clotting system can be out of whack.
The causes of thrombophilia/thrombosis are not fully understood. But here are a few of the possible factors that could increase risk:
The solution? It varies with the individual.
But almost all of us could improve the quality of our diets, with an emphasis on whole plant foods such as vegetables, fruit and nuts and seeds. These dietary components are generally anti-inflammatory, which reduces the tendency for excessive blood clotting.
Those of you who are overweight need to continue your efforts to manage it, even though we all know how challenging that is.
And third, think about nutritional supplements that could improve your blood circulation and reduce excessive clotting tendency. A couple of examples are fish oil and aspirin. A recent Chinese study of mice showed that the combination of fish oil and aspirin acting synergistically to protect against thrombosis. Before taking aspirin, please check with your doctor.
Also, the Women's Health Study has indicated that consumption of vitamin E reduces risk.
Fourth, consult with your doctor if you're taking birth control pills containing combined ingredients. Some ingredient combinations and dosage levels are more conducive to thrombosis than others. Your doctor may wish to adjust the types of ingredients and dosage amounts if you match the known risk factors for thrombophilia.
And finally, no need fret about this. It's just something to be aware of. But regarding a thrombosis, ignorance is not bliss. Learn and implement best health practices. If you do this, you shouldn't have much to worry about.

Have you heard of "naltrexone"? It is a drug used mostly to treat drug and alcohol addiction. But in low doses, some clinicians have been using naltrexone as an "off label" treatment for AIDS, cancer…
