Hot Flushes & Night Sweats
Sudden waves of heat, often followed by chills and sweating, are among the most common indicators of oestrogen decline — particularly during perimenopause and menopause.
Expert, evidence-based HRT for women and men across Australia. Tailored to your hormones, your history, and how you want to feel.
Hormone replacement therapy (HRT) — also referred to as replacement therapy hormones or menopausal hormone therapy (MHT) — is a medically supervised treatment that replenishes hormones the body produces in declining quantities due to ageing, menopause, surgical procedures, or hormonal conditions.
The core hormones involved in most HRT programs are oestrogen, progesterone, and testosterone. Each plays a critical role far beyond reproductive function — they regulate mood, bone density, cardiovascular health, cognition, sleep, libido, and body composition. When their levels fall, the effects can be wide-reaching and disruptive.
At Longevity Clinics, hormone replacement therapy is never a one-size-fits-all prescription. Our clinicians begin with a thorough health assessment and hormone testing to build a picture of what's happening in your body — then design a treatment approach that matches your specific hormone profile, health history, and goals.
Learn About Your OptionsHormonal decline is gradual — which is why many people spend years attributing their symptoms to stress, poor sleep, or simply "getting older." These symptoms are real, they have a biological cause, and they are treatable. Here are the most common signs that declining hormones may be at play.
Sudden waves of heat, often followed by chills and sweating, are among the most common indicators of oestrogen decline — particularly during perimenopause and menopause.
Difficulty falling asleep, waking frequently, or waking unrefreshed are strongly linked to shifts in oestrogen, progesterone, and cortisol. Sleep loss then compounds other symptoms.
Difficulty concentrating, forgetting words, or feeling mentally "slow" can reflect oestrogen's role in cognitive function and neurological health — a symptom that's often dismissed.
Unexplained irritability, low mood, heightened anxiety, or emotional reactivity that feels out of character are closely tied to fluctuating or declining hormone levels.
A significant drop in sexual desire, arousal, or satisfaction is commonly linked to declining testosterone — in both women and men — as well as to low oestrogen in women.
Particularly around the abdomen, weight gain that isn't explained by diet or exercise changes is often driven by hormonal shifts affecting metabolism, cortisol, and insulin sensitivity.
Oestrogen plays a protective role in bone density. As levels decline, the risk of osteoporosis rises — and joint aches become increasingly common, particularly in the hands and knees.
Genitourinary syndrome of menopause (GSM) — including dryness, discomfort, urinary urgency, and recurrent infections — is directly attributable to oestrogen loss and highly treatable.
Not all of these symptoms guarantee a hormonal cause. Our clinicians use comprehensive blood testing and health assessments to confirm what's driving your symptoms before recommending any treatment. If you're experiencing several of these signs regularly, it's worth exploring further.
Hormone replacement therapy is not a single treatment — it encompasses a range of formulations, delivery methods, and hormone combinations. The right approach depends on your symptoms, health history, and personal preferences.
The most common form of HRT for women going through menopause. Oestrogen can be delivered as tablets, patches, gels, sprays, or vaginal preparations — each with different absorption profiles and suitability depending on health history.
Oestrogen combined with progesterone (or a synthetic progestogen) is typically recommended for women who have not had a hysterectomy. Progesterone protects the uterine lining and contributes to sleep, mood, and overall hormonal balance.
Used for both women and men, testosterone replacement addresses low libido, fatigue, muscle loss, cognitive decline, and mood. In women, small doses can have significant impact; in men, it forms the basis of andropause treatment.
Bioidentical hormones are chemically identical to those your body naturally produces. Compounded bioidentical HRT can be tailored to precise dosages not available in standard formulations — though they require expert oversight.
Patches, gels, creams, and sprays deliver hormones through the skin, bypassing first-pass liver metabolism. This is often preferred for women with certain cardiovascular risk factors, as it may carry a more favourable safety profile than oral forms.
Low-dose oestrogen applied directly to vaginal tissue treats genitourinary symptoms — dryness, pain, urinary changes — with minimal systemic absorption. Appropriate for women who prefer not to use systemic HRT but still need targeted relief.
HRT is not exclusively a women's treatment. While it is most commonly associated with menopause, declining hormones affect men too — often under the label of andropause or "low T".
Women experience the most significant hormonal transition during perimenopause and menopause, when oestrogen and progesterone decline markedly. But hormonal imbalance can affect women at any age — from early 30s onward.
Testosterone levels in men decline by approximately 1–2% per year from the mid-30s onward. When this decline becomes clinically significant — a condition sometimes called andropause — the effects on quality of life can be substantial.
From your first consultation to ongoing support, our six-step process ensures nothing is rushed, guessed at, or overlooked.
Speak with a clinician about your symptoms, history, and goals. No rush, no scripts.
Comprehensive review of your medical history, lifestyle, and current health status.
Blood tests to map your exact hormone levels — oestrogen, progesterone, testosterone, thyroid and more.
A personalised HRT protocol designed for your biology, not a textbook average.
Regular follow-ups to monitor your response and fine-tune dosages as your body changes.
Annual tests and scans to ensure continued safety, effectiveness, and long-term health.
HRT has a complicated public reputation — shaped largely by a single study from the early 2000s whose findings were later substantially revised. For most healthy individuals, the evidence strongly supports the benefits of HRT, particularly when started within 10 years of menopause or before age 60.
At Longevity Clinics, every treatment decision is made by licensed Australian medical professionals who weigh your individual risk profile against the potential benefits. There is no blanket recommendation either way.

Hormone replacement therapy (HRT) is a medical treatment that restores or supplements hormones — primarily oestrogen, progesterone, and testosterone — whose levels have declined due to natural ageing, menopause, surgical procedures, or hormonal conditions. It is administered in various forms including tablets, patches, gels, sprays, creams, and vaginal preparations. The goal is to relieve symptoms caused by hormonal decline and, in some cases, to reduce long-term health risks such as osteoporosis and cardiovascular disease.
The most common signs that you may benefit from HRT include persistent hot flushes and night sweats, disrupted sleep, unexplained fatigue, mood changes (including anxiety, irritability, or low mood), brain fog and difficulty concentrating, reduced libido, vaginal dryness or discomfort, joint pain, and unexplained weight gain — particularly around the abdomen. In men, signs include fatigue, muscle loss, low motivation, poor concentration, and reduced sexual function. These symptoms don't guarantee a hormonal cause, but they warrant a proper assessment.
Most people notice some improvement within 2–4 weeks of starting HRT — particularly in sleep, hot flushes, and mood. Full benefit, however, typically takes 3–6 months as hormone levels stabilise and the body adjusts. It's also common to need dosage adjustments in the first few months. Our clinicians monitor your response closely during this period to fine-tune your treatment.
Yes. At Longevity Clinics, the entire process — from initial consultation to ongoing follow-ups — is available via telehealth, making our services accessible to women and men across Australia regardless of location. Blood test referrals can be conducted at a nearby pathology collection centre, and approved prescriptions are delivered discreetly to your home.
For most healthy women and men without contraindications, HRT is considered safe and its benefits outweigh the risks — particularly when started in the early years of hormonal decline. Risks vary by formulation, route of delivery, and individual health profile. For example, transdermal (skin-absorbed) oestrogen carries a lower risk of blood clots than oral forms. Women with a history of hormone-sensitive cancers, unexplained vaginal bleeding, or certain cardiovascular conditions may not be suitable candidates for some forms of HRT. Our clinicians review your full health history before making any recommendation.
Bioidentical hormones are structurally identical to the hormones your body naturally produces (as opposed to synthetic hormones that are similar but not identical). Many standard, TGA-approved HRT medications already use bioidentical hormones (such as micronised progesterone and oestradiol). Compounded bioidentical HRT refers to customised preparations made by compounding pharmacists — useful when precise dosages aren't available in standard formulations. Our clinicians can advise on which approach is most appropriate for your situation.
There is no universal answer. Some people use HRT for a defined period to manage acute menopausal symptoms, then taper off. Others benefit from long-term use — particularly for bone protection, cardiovascular health, and ongoing quality of life. Current evidence does not set a firm upper limit on duration for most women without contraindications. The decision is individual and revisited regularly in partnership with your clinician.
Yes. Testosterone replacement therapy (TRT) and broader hormonal support for men is a core part of our men's health program. If you're experiencing symptoms of low testosterone — including fatigue, low libido, muscle loss, mood changes, or cognitive decline — our clinicians can assess your hormone levels and discuss appropriate treatment options.
Hormone replacement therapy — often simply called HRT — has been one of the most researched, debated, and misunderstood treatments in modern medicine. For women navigating menopause, for men experiencing the effects of declining testosterone, and for anyone whose quality of life is being quietly eroded by shifting hormones, it represents one of the most effective tools available.
Yet despite decades of evidence, myths persist. Many Australians still avoid HRT based on outdated research or incomplete information. This guide covers the essentials: what HRT is, what the signs are that you might need it, what options exist, and what you can realistically expect from treatment.
The term "replacement therapy hormones" refers to the substances used in HRT — bioidentical or synthetic versions of hormones that your body is no longer producing at optimal levels. The most commonly replaced hormones are:
The most common application of HRT is in the management of perimenopause and menopause — the years during which oestrogen and progesterone levels decline, typically from the mid-40s onward. For many women, this transition is far more disruptive than they anticipated.
Hot flushes alone affect up to 75% of menopausal women. But the less-discussed symptoms — brain fog, disrupted sleep, joint pain, anxiety, and a general sense of not feeling like oneself — can be equally or more debilitating. HRT addresses these symptoms directly by restoring the hormones responsible for them.
The current position of the Australasian Menopause Society (AMS) is that HRT is the most effective treatment for vasomotor symptoms and is appropriate for most healthy women under 60 years of age or within 10 years of menopause — where the benefits clearly outweigh risks.
Hormone replacement therapy is not only for women in their 50s. Premature ovarian insufficiency (POI) — menopause occurring before age 40 — affects approximately 1 in 100 women and carries significant health implications if untreated. For these women, HRT is strongly recommended not just for symptom relief but to protect bone density, cardiovascular health, and cognitive function.
Women in perimenopause — the transition years before periods stop entirely — may also benefit significantly from hormonal support, even when they are still having irregular cycles. Many clinicians now recognise that perimenopause is the ideal time to begin HRT rather than waiting for full menopause.
Andropause — the gradual decline of testosterone in men — is now widely recognised as a clinical condition deserving treatment. Unlike the relatively rapid decline experienced by women during menopause, testosterone in men declines slowly — roughly 1–2% per year from the mid-30s. By the time symptoms become obvious, levels may have dropped considerably.
Testosterone replacement therapy (TRT) for men is available in several forms — gels, injections, patches, and implants — and when properly prescribed and monitored, it can produce meaningful improvements in energy, mood, muscle mass, libido, and cognitive clarity.
In Australia, hormone replacement therapy requires a prescription from a registered medical practitioner. TGA-approved HRT medications are available through standard pharmacies, while compounded bioidentical hormones are available through specialist compounding pharmacies on prescription.
Longevity Clinics provides telehealth-based HRT consultations and ongoing management for patients across all Australian states and territories. Our process begins with a comprehensive consultation, hormone blood testing, and a personalised treatment plan — all manageable online, with medications delivered to your home.
