“Estrogen deficiency?”

You need further follow up.

If you have proven that this is so, then it's most likely you could be deficient. Keep taking estrogen. After menopause, stop it as it may have complications.

Limited access to bio-identical hormone replacement is truly a challenge; but KNOWING that you have low Estradiol or age inappropriate Estradiol also means that you have the ability to check your blood levels of Estradiol (and Progesterone) to be able to know that your levels are low. Age inappropriate Estradiol (E) is associated with multiple organ system symptoms including: Short term memory loss, Difficulty cocentrating, Forgetfulness, Insomnia, Early awakening, Dry skin/Dry eyes, Brittle hair, Migraines, Heart palpitations, Muscle aches, Joint pain, Acid reflux/GERD, Shortness of breath with Dry AM cough, Urinary urgency/frequency, voiding middle of night, Urinary incontinence, low libido and painful intercourse. So as you can see, low Estradiol impacts EVERY ORGAN SYSTEM IN THE BODY. Also, realize that low Estradiol levels over several years of menopause is known to lead to calcium loss to a patient’s bones; meaning osteopenia and osteoporosis, another common diagnosis that occurs in menopausal patients.

Estradiol is a generic bio-identical medication that is cost effective and likely available by mail order anywhere in the world; it is the generic of the name brand Estrace. Estradiol is a tablet, and not overly susceptible to temperature extremes; thus it is amenable to shipping that may encounter a time delay in delivery and that a 3 or 6month supply would be stable, even in a tropical environment. However, it is also imperative to know what your Progesterone levels are in relation to your Estradiol levels in order to have a Progesterone/Estradiol dominance; this is important to be proactive in the prevention of thick lining, uterine polyps, uterine fibroids, endometriosis, ovarian cysts and even fibrocystic breast disease. I recommend that you have your healthcare provider check your Estradiol + Progesterone levels every 6months; check on day 21 of your cycle (1wk before your period in a 28day cycle or 3wks from the 1st day of your last cycle). Both Estradiol + Progesterone are available as prescription and in Europe, Estradiol is available without a prescription; Progesterone is yam based and usually prescription only, and usually made in a peanut oil suspension that can go rancid in hot climates. Progesterone caps can also be a powder only cap that is compounded; this would take a little more effort to obtain but would be very stable to ship and would last for months in storage, just take it with 1 teaspoon oil.

I encourage anyone having low Estradiol or low Progesterone to work with their healthcare provider; I also encourage you to order my books: Blossoming, Becoming a Woman (from puberty to approx. mid-late 20years old) or Full Bloom: Perimenopause, Menopause, Postmenopause and Beyond. Both books are available on Amazon as printed book or as Kindle version and then you have a resource to refer to and work with your healthcare provider based on the information in the books.
