What to do when your bioidentical hormones stop working?

by Deborah Maragopoulos FNP | Aug 31, 2018 | Hypothalamus | 7 comments

So you’ve been on bioidentical hormone replacement therapy for a few years. Everything was peachy. You felt good. Hot flashes stopped. You could sleep through the night. Your moods were stable. No more brain fog.

But now you’re having hot flashes again. And night sweats. And you can’t sleep. And you’re peeing yourself every time you laugh. Which is no laughing matter! And your emotions are all over the place. Feels like puberty all over again. But worse, because you have no sex drive and your vagina is dry as a desert.

Oh, my goodness! Can your bioidentical hormones and replacement therapy (BHRT) stop working? YES!

But don’t worry there’s something you can do about it...

First, let’s discuss why your bioidentical hormones might stop working.

Your hormones work by getting into your cells via little doorways called receptor sites. Here’s a sex steroid receptor site.

estrogen receptor

When your receptor sites are no longer sensitive, your hormones can’t get in. We call that receptor site resistance. You may be familiar with insulin resistance. Your cells can become resistant to your sex hormones too.

Why?

Well, your cells never were exposed to the same amount of hormones all the time. When you’re still in your reproductive years having regular periods, your hormones fluctuated throughout your cycle. And at least three days a month starting on the first day of your period, you got a break from estrogen, progesterone, and testosterone. That’s nature’s way of preventing resistance.

Here’s an example of how cell receptor site resistance works.

Let’s say you’re sautéing onions. Your partner walks into the kitchen and says, “Hey, you’re burning the onions!”

You check and sure enough the onions are burning. Why did your partner notice and you didn’t? Because your olfactory receptor sites were saturated by the odor of cooking onions. And your partner’s olfactory receptor sites were completely open, so they smelled what you couldn’t. The same goes for hormone receptors.

It’s just like opiates. You keep using pain meds all the time and you quickly develop tolerance, so you need more and more to get an effect. Eventually they don’t work.

Take a Break

So the moral of the story is... to prevent receptor site resistance, you need to take a break. Specifically three days off every month. That will clear your receptors and allow your hormones to keep working for you. Otherwise, you have to keep using more and more to get an effect, and eventually your hormones will stop working.

So what if it’s too late? Your BHRT doesn’t work anymore. If you’re under 60, then taking a three-week break from your hormones will help clear your receptor sites. Then restarting them should give you similar relief as when you first began your hormones.

Support cell receptivity

You can also increase your dose of Genesis Gold® by 4gm (about a teaspoon) over your body weight (4gm per every fifty pounds) to enhance cellular receptivity and help you metabolize your sex hormones more safely. Whenever I take a break, I add a teaspoon of Sacred Seven® amino acids to my Genesis Gold® to help mitigate the hot flashes and moodiness associated with hormone withdrawal.

Why suffer? I know it’s hard to be off your hormones for a few days, but developing resistance is even harder. So best to prevent it by taking a three-day break from your BHRT every month.

What if you’re over 60 and all of a sudden your BHRT isn’t working?

Well, that’s a little different. Older women still need a three-day break. But now they’re in adrenopause. I like to refer to it as the second menopause. During the ten to fifteen years of menopause, your adrenal glands usually produce enough DHEA that converts into testosterone and then into estrogen, effectively supplementing your BHRT.

Over 60, stressed out

Once your adrenals slow down with age or poop out from stress, it feels like you don’t have enough sex hormones on board. You begin having hot flashes, night sweats, and insomnia all over again. So not only do you need to clear your sex hormone receptors, you need to add adrenal support.

Taking Genesis Gold is an excellent way to support your adrenals. If stress is high, you may need to take a little extra-adrenal glandular for a few weeks. Just don’t take glandular longer than a few months. Glandulars stop working and your liver will treat them as a toxin.

BHRT is NOT WORKING

  • Hot flashes
  • Night sweats
  • Insomnia
  • Depression
  • Anxiety
  • Brain fog
  • Low libido
  • Dry vagina

BHRT IS WORKING if...

You sleep through the night without night sweats.

Your body temperature is normal, no hot flashes.

You have a good sex drive and a juicy vagina to go with it.

Your moods are stable, neither depressed or anxious.

Your memory is good.

 

Q: Why do bioidentical hormones stop working?

A: Bioidentical hormones can stop working when the body’s hormone signaling system—especially the hypothalamus—is no longer responding properly.

Q: Does increasing hormone dosage fix the problem?

A: Increasing dosage doesn’t always help and may worsen imbalance if hormone signaling, not hormone levels, is the underlying issue.

Q: What is hormone resistance?

A: Hormone resistance occurs when tissues stop responding effectively to hormones, even when levels appear adequate.

Q: How does the hypothalamus affect hormone therapy?

A: The hypothalamus regulates hormone signaling throughout the endocrine system, so dysfunction can interfere with how hormones are received and used.

Q: Can stress affect how bioidentical hormones work?

A: Yes. Chronic stress can disrupt hypothalamic signaling and alter how the body responds to hormone therapy.

Q: Is it normal for hormone therapy to stop working over time?

A: Some people experience reduced effectiveness over time, often due to changes in signaling, stress load, or overall hormonal regulation.

Q: What should you consider if hormones stop working?

A: It may be helpful to evaluate lifestyle factors, stress, sleep, and hypothalamic support rather than focusing only on hormone dosage.

Frequently Asked Questions:

Can your hypothalamus cause weight gain?

Yes. The hypothalamus is the master regulator of metabolism, controlling how your body stores and burns energy through its signaling to the thyroid, adrenals, and pancreas. When the hypothalamus becomes dysregulated by chronic stress, poor sleep, inflammation, or blood sugar instability, it defends a higher weight "set point" — causing the body to hold onto fat regardless of diet or exercise. This makes hypothalamic dysfunction an upstream root cause of stubborn weight gain.


What is a weight set point and why won't mine move?

A weight set point is the body weight your hypothalamus works to defend, calibrated over time by stress, sleep, hormones, and inflammation. When you diet, the hypothalamus perceives scarcity and responds by slowing metabolism, increasing hunger hormones, and suppressing satiety signals to return you to that set point. This is why most people regain lost weight within two to five years of conventional dieting — the set point itself was never recalibrated, only temporarily overridden.


Why do I gain weight under stress even when I'm not eating more?

Chronic stress raises cortisol, which disrupts blood sugar regulation, promotes abdominal fat storage, and signals the hypothalamus that the body is under threat. In survival mode, the hypothalamus defends fat stores and slows metabolism — so weight can increase even without any change in calorie intake. The stress chemistry, not the food, is driving the weight gain, which is why stress reduction is essential to any lasting metabolic reset.


Why do I regain weight after stopping GLP-1 medications?

GLP-1 medications work peripherally on appetite and gastric signaling, but they do not address the underlying hypothalamic dysregulation that sets your defended weight. Because the hypothalamic set point is never recalibrated, the body resumes defending its original weight once the medication stops — leading to significant regain. Long-term success requires restoring hypothalamic regulation so the set point itself lowers, rather than relying on appetite suppression alone.


How long does it take to reset your metabolism?

Genuine metabolic recalibration takes a minimum of 90 days, because the hypothalamus needs consistent signals of safety and sufficiency before it will lower its defended set point. This differs from a diet, which produces temporary suppression the body quickly corrects. A 90-day reset typically moves through three phases: stabilizing stress chemistry (days 1–30), rebuilding metabolic efficiency (days 31–60), and lowering the weight set point (days 61–90).


Why does my thyroid feel slow even though my labs are "normal"?

Under chronic stress, the body converts thyroid hormone into reverse T3, which blocks active thyroid receptors and slows metabolism at the cellular level — even when standard lab values appear normal. This means you can experience genuine symptoms of slow metabolism, such as fatigue, cold intolerance, and brain fog, while your thyroid panel looks unremarkable. Addressing the upstream hypothalamic and stress signaling often improves thyroid conversion and symptoms.


Is stubborn weight gain a willpower problem?

No. Stubborn weight gain is a signaling problem, not a willpower problem. The hypothalamus governs weight through survival mechanisms that operate below conscious control — defending its set point by slowing metabolism and increasing hunger when it perceives threat. No amount of discipline can override this system; lasting change comes from restoring hypothalamic regulation through reduced stress, balanced blood sugar, restorative sleep, and targeted nutritional support.

    I am a 69 year old female that had a hysterectomy at age 28. I have been on and off hormones since hysterectomy. the creams stop working,so i tried the pellets insertion of Bio-identical hormones in my buttocks. worked for almost 2 years but have stopped. Recently had new insertion of pellets. had bloodwork done 6 weeks following insertion of pellets. All hormone in bloodwork show that they are too high. I am experiencing symptons of hot flashes, cant sleep, heart palpitations, vaginal dryness, NO LIBIDO. I am married and my husband and i still have a decent sex life. what can I do to help my receptor sites so the hormones will work better. I cant get off of them since they are inserted in my buttocks. I do know that I will not be getting them until at least 6 months. My doctors said i was hormone sensitive and nothing he could do. Can you help

    I’ve been on pellets for about 5 years. When I started, gained 10 immediately which was muscle. Great, because I lost muscle and weight from having no hormones. Now my estrogen and testosterone are too high and I’ve gained an additional 10! Plus big puffy bags under my eyes. Also, twice I’ve expelled my pellet. The last one I expelled was 3 months old and only halfway dissolved.

      I am not a fan of pellets for menopausal hormone replacement therapy
      Here’s my take on pellets from my Menopause Action Plan book, have you read it?
      https://genesisgold.com/books/menopause-action-plan/

      Twenty years ago, I had a few patients interested in trying pellets for hormone replacement therapy, so I did a little research. Pellets use bioidentical hormones, and are created in a compounding pharmacy so I could individualize the dosing. Pellets weren’t good at delivering progesterone, so we still had to use progesterone in a different form, usually transdermally.

      The issue I found with pellets is first, you need to have them injected every few months. Number two, we cannot control the amount of hormones you’re going to absorb. Even though pellets are compounded to the prescriber’s recommendation, some women’s bodies suck the hormones out quickly, giving them super high levels initially, which may give them extreme side effects, but then the effects wear off. Some women barely get any hormone from the pellets, and so it lasts a long time in their system. We can’t control it. So if it’s not going to work for you, you’re stuck with those pellets until they dissolve, which could take three to five months.

      Although I’m not a big fan of pellets as a form of hormone replacement therapy, it’s an easy way for providers who don’t know much about how to prescribe hormone replacement therapy to send their patients’ blood work to the pellet company and have the pellets compounded for that particular patient. The problem is that blood work does not always reflect your hormone needs, determined by your symptoms, your risk factors, or your history. Your pituitary FSH and LH are more reflective of how much of each hormone you need at any particular point in the change. I don’t go by your blood levels of estrogen, progesterone, and testosterone to determine the dose of hormones you’re going to need, because your tissue levels and what’s floating around in your blood are two different things. Since the dosages cannot be adjusted for at least three months, I don’t use pellets in my patients.
