Ep. 15: 3 Myths of Hormone Replacement Therapy: Truth or Dare! — with Dr. Lorraine Maita, Hormone Expert

Should women use hormones in menopause — or are they too dangerous? In this myth-busting conversation, Dr. Regina Druz welcomes Dr. Lorraine Maita, a triple board-certified functional and anti-aging physician known as ‘The Hormone Harmonizer.’ Together they revisit the 2002 Women’s Health Initiative that scared a generation of doctors and patients away from hormone therapy, and explain what decades of re-analysis have actually taught us about timing, dose, and the difference between synthetic and bioidentical hormones. Dr. Maita then busts three big myths: that hormones cause breast cancer, that hot flashes are harmless, and that menopause is simply ‘one year without a period.’ She also walks through her detoxification-first approach — estrogen metabolites, methylation, gut health, and cortisol — that she uses before ever writing a hormone prescription.

[00:00] Introduction & Meet Dr. Lorraine Maita

Dr. Regina Druz (00:00): Welcome to Own Your Heart Health. I’m Dr. Regina Druz, your holistic cardiologist. This week we’ll dive into common heart health concerns, uncovering root causes and unpacking scientific discoveries and controversies. The information provided does not constitute medical advice. Please contact your healthcare practitioner before making any changes that may impact your health.

Dr. Regina Druz (00:30): Hello there, wonderful listeners — happy Friday. Today I’m thrilled, because we’re doing something I’ve wanted to do for a very long time: bring an expert to talk about the hormones. You’ve heard it all over the place — menopause, perimenopause, should we use hormones, bioidentical or not? Please set your biases and misconceptions aside and open your mind to Dr. Lorraine Maita, an absolute star hormone expert. Welcome, Lorraine.

Dr. Lorraine Maita (01:15): Thank you for having me. I’m here to bust the myths, because they’ve been out there for a very long time — long before the latest wave of misinformation — and the truth is hormones are safer than you think.

[02:00] An Undercover Hormone Doctor: Her Origin Story

Dr. Regina Druz (02:00): I love that — ‘hormones are safer than you think.’ Tell us about your interesting career arc and how you grew up to be a hormone expert.

Dr. Lorraine Maita (02:15): Before medical school I worked under a leading IVF expert at NYU when it was brand new, and I fell in love with hormones. I considered OB-GYN but chose internal medicine. Then, working in the emergency room, I contracted tuberculosis and was on antibiotics for nine months. It cured the TB but left me a mess — gaining weight, rashes, yeast infections, hair loss, fatigue, brain fog. That’s how I discovered functional medicine and how central the gut is to overall health. It worked; I became myself again, and I figured if it happened to me, it’s happening to others. I took the Institute for Functional Medicine course under Jeffrey Bland — I was in the first graduating class.

Dr. Lorraine Maita (04:00): Then a senior female executive came to me, terrified: she’d been giving a lecture when a hot flash hit — sweat pouring, train of thought lost, men in the room snickering — and she said, ‘How will I be taken seriously? You have to help me.’ I didn’t know much about menopause yet, so I went back to NYU, trained under the hormone experts there, and started recommending bioidentical hormones when almost no one knew about them. I had to do it almost undercover, because back then people would accuse you of practicing ‘alternative’ medicine — and to me it was just common sense.

[06:00] Prempro & the Pre-WHI Era

Dr. Regina Druz (06:00): Let’s stop there — because listeners may not know why you couldn’t talk about this. What was going on in medicine at the time around hormone replacement therapy?

Dr. Lorraine Maita (06:30): Back then Prempro was big. The thinking was that when a woman goes into menopause and her estrogen and progesterone wind down, she starts ‘catching up to men’ on heart disease, so we should replace the hormones. Wyeth made Premarin — conjugated estrogen from horse urine, given orally — and Provera, a synthetic progestin; combine them and you get Prempro. When I trained, it was almost considered malpractice not to put a menopausal woman on hormones; Premarin, Provera, and Prempro were among the most prescribed drugs in the country. But the women on Prempro often didn’t feel good — depression, breakthrough bleeding — because at the time we didn’t have oral micronized progesterone.

[08:30] The Women’s Health Initiative: What Really Happened

Dr. Regina Druz (08:30): Then came the watershed moment — the Women’s Health Initiative. I want listeners to understand we went 180 degrees. I literally remember being a resident, called into my attending’s office and told to phone all my patients and stop every hormone prescription, immediately. Tell us about the study.

Dr. Lorraine Maita (09:30): The Women’s Health Initiative was designed mainly to see how long after menopause you could give hormones — not how safe they were or when was best to start. They gave high-dose synthetic hormones to women whose average age was 63, about ten years past menopause. As I tell people, by then the ship has sailed; a lot of damage is done. They didn’t address lifestyle at all. It was a very large, expensive study — which is why it’s still quoted and re-dissected to this day. The press got hold of it, publicized an increased risk of heart attack, stroke, and breast cancer, and the study was stopped early. That fear got fixed in people’s minds, and it’s still there — and that was 2002.

Dr. Regina Druz (12:30): The premise was reasonable for its time, though — it was one of the studies that put hard outcome measures (heart attacks, strokes, blood clots, breast cancer) at the center of research, which wasn’t yet the norm. So what did they actually find that was concerning?

Dr. Lorraine Maita (13:00): They found about eight more cases of breast cancer and an increased risk of heart attack and stroke, which is why they halted it. But we’ve learned so much since. At the time all they had was oral estrogen and oral synthetic progestins. Oral estrogen passes through the liver, which makes clotting factors — so you get more clots, and clots can travel to the brain (stroke) or heart (heart attack). You get the same risk from birth control pills, which are also synthetic, yet no one bats an eye at those. Once they began giving estrogen through the skin — patches and creams — the clot risk became negligible, and the heart-attack and stroke risk went way down.

[16:00] What We Learned Since WHI: Timing, Form & Dose

Dr. Regina Druz (16:00): So let’s summarize. The Women’s Health Initiative used oral synthetic hormones in older women long past menopause and showed increased events, so it was stopped early for a harm signal — and that created lasting stigma. Official cardiology positions still often cite small risk over benefit. But the lessons since have been more nuanced, and they’re paving the way for a new era of hormone therapy. What did we learn?

Dr. Lorraine Maita (17:00): A few key things. Among women who’d had a hysterectomy and took estrogen alone — no progestin — there was actually a decreased risk of breast cancer; the synthetic progestin appeared to be the culprit. The control group also happened to have a lower-than-average breast-cancer risk, so the comparison made hormones look worse than they were. And timing mattered enormously: in women under 60 and within ten years of menopause, the benefits outweighed the risks — the sooner you start, the better, and some things are best started in perimenopause. A recent Swedish study found that once we changed how hormones are given, the risk of ischemic heart disease dropped by about 50% — and the longer women stayed on them, the better.

[20:30] Myth #1: Hormones Cause Breast Cancer

Dr. Regina Druz (20:30): You’re a myth-buster, so let’s bust some myths. Based on all these studies, what’s the number-one myth people think is true but is actually false?

Dr. Lorraine Maita (21:00): That hormones cause breast cancer. Even in the Women’s Health Initiative, estrogen alone decreased breast-cancer risk. Subsequent studies show oral micronized progesterone — natural, bioidentical progesterone, not the synthetic — is safer; some show decreased risk, most show no increase, a few show maybe a very slight risk after five years. And unlike synthetic progestins, bioidentical progesterone doesn’t negate estrogen’s positive effects on the heart and blood vessels. Give estrogen through the skin and you don’t see the heart-attack and stroke risk. The North American Menopause Society and at least twenty other organizations have now concluded that for many women the benefits outweigh the risks. Bioidentical hormones also don’t cause the coronary-artery spasm, gallstones, raised blood pressure, diabetes risk, or androgenic side effects that some synthetic progestins do — it’s a matter of finding the dose that relieves symptoms and restores quality of life.

Dr. Regina Druz (24:00): Hi everyone, it’s Dr. Regina here. I know there are contradictory opinions about nutrition for heart health and longevity — the discussion gets heated and confusing. Some push low-fat, low-cholesterol; others are fans of a ketogenic diet; and there are many voices urging vegan or vegetarian eating. To cut through the clutter, my team and I created Holistic Heart University: on-demand courses, nutrition and lifestyle resources, and supplement guidance to make healthy choices for your heart easier to understand. I’m especially proud of our open office hours and the Q&A feature where you can put us in the hot seat.

[25:30] Risk Assessment & the Breast-Cancer Picture

Dr. Regina Druz (25:30): You’re hitting important points. First, individualization — which, in cardiac patients, also means proper risk assessment, and there are gaps in our knowledge. In the Women’s Health Initiative, some women had coronary disease but were never assessed for subclinical disease, because tools like calcium scoring existed but weren’t widely used in 2002. Second, we’re seeing breast cancer rise, especially in younger women — likely a different phenomenon than older-onset breast cancer, with toxic exposures playing a role — and how bioidentical hormones interact with that is still gray. And third, the timing window matters: ideally we consider hormones before hypertension, dyslipidemia, full metabolic syndrome, or occult insulin resistance set in. So that’s myth one busted. What’s myth two?

[27:30] Myth #2: Hot Flashes Are Benign

Dr. Lorraine Maita (27:30): Many women tell me, ‘Hot flashes will go away,’ or ‘I can live with them.’ But hot flashes are a biomarker of something else happening in your body. They raise your risk of cardiovascular disease, dementia, bone loss, and inflammation — and inflammation is the root cause of most chronic conditions; we age from ‘inflammaging.’ I did a deep dive on hot flashes and all their implications: they are not benign. They’re your check-engine light. If you ignore it, something inside breaks down. Beyond risk, there’s quality of life: the top four reasons women come to me are fatigue, poor sleep, brain fog, and weight gain — all tied to hormones. Often it’s the husband who sends his wife in, as an act of kindness, because he knows something is wrong.

Dr. Regina Druz (29:30): This is worth repeating, because hot flashes are usually treated as benign — there’s so much marketed to just suppress them. But like an abnormal blood-pressure reading, a hot flash should prompt concern, because its origin is systemic and it reverberates through the cardiovascular system. Some of those cardiometabolic changes will progress or become irreversible without attention.

[31:00] Myth #3: Menopause Is “One Year Without a Period”

Dr. Lorraine Maita (31:00): There are so many misconceptions — including about what menopause even is. The textbook definition is one year without a period, but there are about 35 symptoms. Low estrogen affects memory; the oral microbiome (gum and tooth health, and protection against respiratory infections); it can cause burning-mouth syndrome and more cavities; and it changes the GI tract — gas, bloating, belching. So menopause is far more than a missed year of periods.

Dr. Regina Druz (32:30): I’d add labile hypertension and the first lipid abnormalities — a ‘metabolic pattern’ appearing in the labs of a woman whose cholesterol used to be optimal. So myth three is busted: menopause is a complex, often subclinical syndrome that women frequently don’t recognize, because the symptoms get attributed to something else. So let’s summarize: hormones don’t cause cancer; hot flashes are a systemic warning sign, not a nuisance; and menopause is far more than one year without a period.

[35:00] The Maita Method: Assessment & Education

Dr. Regina Druz (35:00): So a woman like me comes to you — mid-fifties, in menopause — and asks what to do. How do you assess women and safely begin hormone therapy? What are the guardrails?

Dr. Lorraine Maita (35:30): First I educate, because every patient will get pushback — from family, friends, even other clinicians. I can cite a study for everything; I’ve done this 30-plus years and write blogs weekly. Then I assess quality of life and symptoms: ‘I don’t feel like myself,’ ‘my life went from technicolor to black and white,’ poor sleep, weight gain, low libido, painful sex, recurrent urinary infections. I ask which symptoms could be related to lack of hormones and could improve with replacement. I weigh the risks of not taking hormones — dementia, osteoporosis, cardiovascular disease — against the risks of taking them. Done right (transdermal estrogen, bioidentical progesterone), the main contraindications I honor are a personal history of breast cancer, prior blood clots or pulmonary embolism, and high-risk genetics like BRCA.

Dr. Regina Druz (39:30): I’m rigorous about screening too — annual mammogram, often with ultrasound, and breast MRI for very dense breasts — for anyone considering or on hormone therapy. And for breast-cancer risk specifically, there’s the Tyrer-Cuzick risk-assessment calculator, available online and used at imaging facilities; we’ll link it in the show notes.

[42:00] Detox, Estrogen Metabolites & the DUTCH Test

Dr. Lorraine Maita (42:00): They call me the Hormone Harmonizer and Detoxifier, because before I start hormones I decrease inflammation and detoxify every woman who comes to me — and within two weeks, about 80% feel good to great. Detox means reducing what’s coming in — clean food and water, organic where it counts, fewer toxins from personal-care and cleaning products, and never heating food in plastic, because plastics are hormone disruptors and ‘obesogens.’ Then I support the liver to clear toxins out, often with milk thistle, Jerusalem artichoke, and N-acetylcysteine or glutathione. I also calm the gut — 80% of the immune system lives there — with a short elimination diet and an anti-inflammatory shake, and I keep bile flowing, because bile binds estrogen’s breakdown products.

Dr. Regina Druz (46:00): On that — there’s a lot of focus on testing estrogen metabolites, because some breakdown products can recirculate and cause harm. Are you testing those and treating accordingly?

Dr. Lorraine Maita (46:30): Yes — with the DUTCH test. In a woman with very little estrogen it’s less accurate, so for perimenopausal women, anyone with PMS, or high estrogen, I do it right away; in women with low estrogen not yet on hormones, I wait until we replenish. Picture the liver as a recycling plant sorting estrogen into benign, semi-toxic, and very toxic breakdown products. If you make too much of the toxic ones, I give indole-3-carbinol and DIM to shift you toward the benign pathway. Then, like any garbage, it has to be packaged for removal — that’s methylation. If you don’t methylate well, you reabsorb those products, so I check whether you can methylate. And my pet peeve is constipation: if you’re not having a daily bowel movement, it’s like flushing a backed-up toilet — everything you’re trying to eliminate goes right back in. So fiber, and regularity, matter.

[51:00] Targets, Cortisol & Treating the Person

Dr. Regina Druz (51:00): So replacement is the icing on the cake — its power is realized only once the context is right. What are your goalposts? Are you targeting a specific estradiol level?

Dr. Lorraine Maita (51:30): I start with detailed blood work — looking for metabolic syndrome and checking all the hormones, because every hormone affects every other — and I measure cortisol in saliva, because the stress hormone, whether physical, emotional, or chemical, will throw off everything else. While we wait for results, we do the detox and elimination diet, then a symptom questionnaire before and after, because people normalize symptoms they’ve simply learned to live with. We want mood, energy, weight, and sleep to improve first; the hormones are the cherry on top. For levels, I’ll aim for estradiol around 50 to 100 and progesterone around 8 to 10 — but you treat the person, not the number. Some women can’t tolerate those levels, and that’s fine: even the lowest dose protects bone, and they’ll still sleep, hold their weight, and protect brain and skin.

Dr. Regina Druz (53:30): Hi everyone, it’s Dr. Regina here. Many of my colleagues and I are seeing patients arrive with self-ordered blood tests. When this trend started, I thought it would help — who doesn’t want more access to their health data? But too often self-ordered labs lead to more confusion and frustration: patients come in with a pile of results and are no better off. That’s why we created HeartWell Toolkits — a curated collection of at-home blood and genetic markers focused on heart and brain health that gives you the data you need to make informed, actionable decisions. You can order them at the shop on holisticheartcenters.com — the link is in the show notes. Use code TESTING10 for 10% off and free shipping.

Dr. Regina Druz (55:00): I aim for the same 50-to-100 range, and you’re entirely right that some women benefit at lower doses and some need a bit more — so we start low and go slow, detox, and assess cardiac risk first, because the Women’s Health Initiative did teach us that older women with preexisting coronary disease may be a different group. And I’ll add: I’m floored by how many young women now have subclinical coronary disease — I just saw a woman in her mid-fifties with a calcium score of 456. So due diligence on cardiac risk matters before and during hormone therapy.

[58:00] Closing: Bring Back Joy + For Clinicians

Dr. Regina Druz (58:00): Any closing words for our listeners, Lorraine?

Dr. Lorraine Maita (58:15): Bring joy back into your life — it calms your nervous system, and your nervous system affects your hormones. Have some fun and express gratitude; even on the worst day, find one thing to be grateful for. It helps your heart, your nervous system, your hormones, and your immune system. And remember, I measure hormones three ways — blood, urine, and saliva.

Frequently Asked Questions

Do hormones (HRT) cause breast cancer?

According to Dr. Maita, this is the number-one myth — and the evidence is more reassuring than most people believe. Even in the Women’s Health Initiative, women who took estrogen alone had a decreased risk of breast cancer; the signal of increased risk was tied to a synthetic progestin, not estrogen itself. Subsequent research on natural, bioidentical (oral micronized) progesterone shows it is safer — most studies show no increase, some show a decrease, and a few suggest only a very slight risk after about five years. She still observes standard contraindications, declining hormone therapy for women with a personal history of breast cancer, prior blood clots, or high-risk genetics such as BRCA, and she emphasizes rigorous breast screening for anyone considering or using hormones. This is educational information; decisions about hormone therapy should be made with your own physician.

What did the Women’s Health Initiative actually find — and why did it scare everyone?

The 2002 Women’s Health Initiative gave high-dose synthetic hormones (oral estrogen plus a synthetic progestin) to women whose average age was 63 — about ten years past menopause — and was designed to study how long after menopause hormones could be given, not how safe they were or when to start. It was stopped early after finding a small increase in breast cancer (about eight additional cases) and in heart attack and stroke, and the press amplified those findings into a lasting fear. Decades of re-analysis have added crucial nuance: oral estrogen raises clotting risk by passing through the liver (transdermal estrogen largely avoids this), the synthetic progestin drove much of the breast-cancer signal, the comparison group had unusually low baseline risk, and timing matters enormously. Always interpret studies, and your own options, with a qualified clinician.

Are hot flashes harmful, or just annoying?

Dr. Maita argues they are far from benign — she calls a hot flash a ‘check-engine light.’ Beyond disrupting quality of life (fatigue, poor sleep, brain fog, and weight gain are the top reasons women seek her help), hot flashes are a biomarker linked to higher risk of cardiovascular disease, dementia, bone loss, and inflammation — and inflammation (‘inflammaging’) underlies most chronic disease. Dr. Druz adds that, much like an abnormal blood-pressure reading should prompt concern, a hot flash signals systemic, neuroendocrine, and vascular changes that can progress or become irreversible if ignored. The takeaway is not to panic over a single hot flash, but to treat it as meaningful information worth discussing with your clinician rather than simply suppressing. This is general education, not individualized medical advice.

Is there a “right time” to start hormone therapy?

Timing is one of the biggest lessons from the re-analysis of the Women’s Health Initiative. Both physicians describe a ‘window of opportunity’: in women under 60 and within about ten years of menopause, the benefits of hormone therapy more often outweigh the risks, and some benefits are best captured by starting in perimenopause. Starting much later — once arteries are already significantly hardened — is less able to reverse cardiovascular changes, though hormones may still be used thoughtfully for symptoms, bone, and brain health in selected women. Dr. Druz emphasizes assessing cardiovascular risk (including subclinical disease) before and during therapy, and Dr. Maita stresses individualization, detoxification, and starting low and slow. The right timing and approach are highly personal — work them out with a clinician experienced in hormone therapy.
