A personal history of blood clots (such as deep vein thrombosis or pulmonary embolism) or serious cardiovascular disease (like heart attack or stroke) is a key factor in deciding whether hormone therapy (MHT) is appropriate and, if so, which type is safest. Here at Alloy, we want to ensure your safety and tailor treatment to your unique history: - Oral estrogen (like the estradiol pill) and low-dose birth control pills are generally not recommended for people with a personal history of blood clots or serious cardiovascular disease. - Transdermal estrogen options (patch, gel, or spray) may be considered safer for some people with a history of provoked blood clots (those caused by surgery, trauma, or immobility), as studies show these forms do not significantly increase clot risk. However, this decision should always be made in consultation with a menopause-trained doctor and, often, a hematologist or cardiologist. - If your blood clot was unprovoked (no clear cause) or you have a genetic clotting disorder, extra caution is needed, and hormone therapy may not be advised. - For those with a personal history of heart attack or stroke, hormone therapy is generally not recommended, but there can be exceptions in special cases with close medical supervision. It's essential to work with a menopause specialist to review your individual risks and benefits. At Alloy, our intake process ensures a menopause-trained doctor will review your medical history and help you find the safest and most effective solution for you.
