S4 Ep174: Is Your Transdermal ESTROGEN... Getting ABSORBED?

Transdermal estrogen in the form of a patch, gel, or cream is often the preferred delivery method for menopausal hormone therapy. Unlike oral estrogen, in addition to other advantages, transdermal estrogen does not increase the risk of blood clots. But a new study, published in the journal Menopause, indicates that your transdermal estrogen… may not be doing what you think it’s doing. Today, I am speaking with one of the authors of that study, Dr. Louise Newson.  My Substack post summarizing the study:  https://drstreicher.substack.com/p/is-your-estrogen-patch-gel-or-spray?r=740mq Link to article: https://pubmed.ncbi.nlm.nih.gov/39689249/ We discuss:

• The advantages of transdermal estrogen
• The realization that blood levels of transdermal estrogen may be below what is expected
• What the study looked at
• Results of the study
• What factors may cause decreased absorption of transdermal estrogen
• Why decreased levels of estrogen are problematic
• Ways to maximize absorption
• Options if serum estrogen levels are low on standard doses of transdermal estrogen
• Concerns of using a higher than standard dose
• The pushback in the UK regarding Dr. Newson’s work
• If it should be routine to measure blood levels of estrogen if using a transdermal product
