How to Fix Your Progesterone to Estrogen Ratio For The Last Time
One of the most commonly used metrics to assess female hormone imbalances is to look at the Progesterone to Estradiol ratio, often called the Pg/E2 ratio. When this ratio is less than 200 to 1 symptoms of hormonal imbalance can quickly arise. E2 refers to an estrogen known as estradiol, but there is way more to the story than just high estrogen and low progesterone. In fact, while I find the information very valuable, what you do with the information and how to improve your estrogen and progesterone ratios is more complex than just having numbers.
If you want to learn how to fix your progesterone to estrogen ratio, balance your hormones, and reverse your symptoms with expensive drugs and frequent doctor visits, keep on reading!
Understanding Your Progesterone to Estradiol Ratio
If you are unfamiliar with what the Pg/E2 (progesterone to estrogen) ratio is, it is something many physicians use when a woman suffers from hormonal symptoms, yet their lab results appear to be within the “normal” range.
I won’t go into the exact calculations as of now, but essentially in both saliva and blood tests, you are aiming for a progesterone to estrogen ratio of 100-500. (To calculate your progesterone to estrogen ratio, take your progesterone and divide it by your estrogen which then provides your progesterone to estrogen ratio. Providers vary but I have observed many practitioners aiming at a progesterone to estrogen ratio greater than 200.)
When progesterone is low in relation to estrogen, then your ratio goes lower. This is what is termed estrogen dominance and is most common especially in women over the age of 40. This also suggests relative progesterone deficiency. (For more on estrogen dominance, read my article here.)
When progesterone is high in relation to estrogen then it is described as progesterone dominance. This also suggests a deficiency of estrogen relative to progesterone.
11 Symptoms of Progesterone to Estrogen Ratio Deficiency (aka Estrogen Dominance)
- Mood changes
- Hot flashes
- Low libido
- Menstrual problems (short, long, heavy, irregular)
- Menopause symptoms
Standard Natural Treatment For Optimal Progesterone to Estrogen Ratios
This is where I am going to part ways with many natural doctors or better stated semi-natural doctors. In 2018 the standard “go-to” treatment for estrogen dominance is hormone replacement therapy (HRT) using progesterone to increase progesterone while leaving estrogen the same and thus improving the Pg/E2 ratio. While not everyone is doing this, the vast majority are.
The standard treatment for Progesterone dominance is to use HRT to provide additional estrogen and thus fixing the ideal ratio (100-500).
(I also note that this is an oversimplified example but illustrates the point.)
I personally have a problem with hormone replacement therapy and I think you should too. The problem is that nobody seems to be asking the deeper question of why these ratios are off in the first place! Why in 2018 do so many women need HRT when in even as recent as the year 2000 you were hard pressed to find a women on HRT?
I thought natural practitioners were supposed to be looking for the root cause?
What happened to the days when the physician would dig deep into their wisdom and knowledge base for answers rather than simply prescribing “natural” hormone replacement therapy? If you are missing your ovaries and or uterus, or have other extenuating circumstances then there may be a valid reason for hormone replacement, but otherwise the most natural way to balance your hormones permanently is to avoid adding hormones altogether.
In a subsequent article I will address all the negative side effects of HRT, but for now, know that the biggest problem in my opinion isn’t cancer risk, but rather that it forgets to dig into the WHY and look for a root cause, thus it makes it much like other prescription drugs that only address symptoms. (Yes, I realize that this is a highly controversial statement.)
How to Correct Your Ratio 95% of the time
I get the opportunity to work with a lot women in my practice. Most women don’t come in complaining of hormonal imbalance, yet most have an imbalance that appears during the course of treatment and what I find 95% of the time is that what shows up in the treatment process is high estrogen. The other 4% is low progesterone usually due to excessive stress and there is always the remaining 1% which can be much more complex.
So… if I was a female at home reading this article and guessing which was causing my symptoms regarding libido, hair growth, cramping, tenderness, mood swings, etc. I would guess it was high estrogen.
In fact I would go so far as to say that, even if you are a female that has blood or saliva labs from your doctor that suggest your estrogen is low or even “undetectable” I would still suggest that you are much more likely to have estrogen excess and/or estrogen dysregulation than a true progesterone deficiency.
This does not mean that you shouldn’t treat your progesterone to estrogen ratio, it just means that in my opinion, the best way to balance your Pg/E2 ratio is to lower estrogen almost every time.
Part 2 will cover the detoxification of estrogen so that you don’t fight a never-ending battle of hormone balancing and returning symptoms. I will also cover how to significantly increase your progesterone without HRT.
