Understanding the Perimenopausal Transition, Hormonal Foundations, and the Role of BHRT
Women are more than a collection of symptoms they are whole individuals who deserve to feel well, function optimally, and thrive at every stage of life.
Healthcare should take a holistic, patient-centred approach, supporting not only physical health but also emotional wellbeing, cognitive clarity, energy, vitality, and overall quality of life.
Hormones Are Protective
PROGESTERONE has calming, mood-stabilising, and protective effects, helping to balance oestrogen and support sleep, mood, and cycle regularity. It is often the first hormone to decline in perimenopause due to irregular ovulation, which may contribute to anxiety, poor sleep, mood changes, and heavier or irregular periods.
OESTROGEN supports tissue repair, bone, cardiovascular, brain, skin, and vaginal health, as well as overall vitality. During perimenopause it fluctuates before declining, which may lead to symptoms such as hot flushes, night sweats, mood changes, brain fog, and urogenital symptoms. Oestrogen and progesterone work together to maintain hormonal balance.
TESTOSTERONE supports energy, motivation, libido, muscle and bone strength, cognition, and overall wellbeing. Levels gradually decline during perimenopause, which may contribute to reduced energy, lower libido, decreased strength, and changes in mood or mental clarity.
Overall, perimenopause is characterised by fluctuating oestrogen, declining progesterone, and gradually reducing testosterone, contributing to the wide range of physical and emotional symptoms experienced during this transition. Menopause is defined as the point at which menstrual periods have permanently stopped due to a sustained reduction in ovarian hormone production, typically confirmed after 12 consecutive months without a period.
Understanding Functional Medicine in Peri Menopause & Menopause Care
Functional medicine offers a personalised approach to supporting women through menopause. Rather than focusing solely on hormone levels, it considers the wider picture, including medical history, nutrition, stress, sleep, lifestyle, physical activity, and broader health patterns across all body systems, including metabolic flexibility, inflammation, total toxic load, biotransformation, detoxification pathways, and others.
Common Perimenopause & Menopause Concerns Addressed in Functional Medicine
Many women seek functional medicine support when perimenopausal and menopausal symptoms begin affecting their daily lives and wellbeing. Symptoms can vary widely and may include:
• Hot flushes and night sweats
• Fatigue and low energy
• Brain fog, poor concentration, and memory changes
• Anxiety, irritability, mood fluctuations, depressive symptoms, and reduced stress tolerance
• Sleep difficulties and waking during the night
• Weight gain, bloating, and changes in body composition
• Digestive issues and gut discomfort
• Joint pain, muscle aches, stiffness, and inflammation
• Irregular or heavier periods
• Headaches
• Low libido and painful intercourse
• Vaginal dryness
• Skin and hair changes
• Recurrent urinary tract infections (UTIs), increased susceptibility to yeast infections, and urinary frequency
These symptoms can significantly affect energy, sleep, cognitive clarity, emotional wellbeing, physical comfort, body confidence, intimate relationships, and overall quality of life.
*Interestingly, women who experienced mental health disorders postpartum are more likely to experience similar challenges during perimenopause.
How Functional Medicine Supports Women Through Perimenopause & Menopause
Functional medicine offers a comprehensive, personalised approach that focuses on identifying and addressing the underlying factors contributing to these symptoms.
Rather than managing each symptom in isolation, functional medicine examines how hormonal changes influence the body's interconnected systems.
The goal is to help women navigate menopause with greater balance, resilience, and long-term well-being.
At Lithe Health Clinic, we meet each woman where she is, providing integrative, personalised, whole-person, supportive care tailored to her individual needs throughout the perimenopausal transition.
We focus on identifying and addressing the root causes of symptoms, strengthening the foundational pillars of health, and using evidence-based nutritional therapy. Personalised supplement and nutraceutical protocols, along with lifestyle interventions, may provide targeted support before considering BHRT.
When hormone therapy is clinically indicated, it is incorporated as part of a personalised, comprehensive healthcare plan designed to support optimal health, resilience, and long-term wellbeing, including support for key metabolic and hormonal pathways and the modulation of inflammatory processes.
Safety is central to personalised care. For this reason, BHRT is not appropriate for everyone. Careful assessment of medical history and clinical needs, consideration of patient preferences and the timing hypothesis, individualised dosing, and ongoing monitoring are essential to ensure treatment is both safe and effective.
Successful hormone therapy is about more than simply prescribing hormones; the body must also be able to absorb, utilise, regulate, and safely eliminate them.
This is where functional medicine plays an important role, addressing key factors such as metabolic flexibility, liver and gut detoxification pathways, methylation, optimal thyroid and adrenal function, and hormone receptor function all of which influence how effectively and safely an individual responds to treatment, without neglecting the foundational pillars of health.
Functional medicine helps optimise hormone balance by supporting the body’s underlying systems, while BHRT directly restores hormones when deficiencies are present.
The most effective and sustainable outcomes are often achieved when these approaches are combined.
Together, they can promote hormonal balance, metabolic resilience, and long-term health.
BHRT vs Conventional HRT - what’s the difference?
The key difference is how the hormones interact with the body.
BHRT (bioidentical hormones) are chemically identical to the body’s own hormones, so they are processed in a very similar way to natural hormones. BHRT is also highly personalised in terms of formulation (transdermal or oral) and dosing. Many patients report good tolerability, particularly with micronised progesterone and 17β-oestradiol.
Conventional HRT can also use bioidentical hormones, but it often includes synthetic progestins or conjugated oestrogens, which interact with hormone receptors in different ways and may have less favourable metabolic effects. In some people, this may be associated with a higher likelihood of side-effect profiles and broader adverse systemic effects on the body. Synthetic progestins and conjugated oestrogens may cause side effects such as mood changes, bloating, fluid retention, breast tenderness, headaches, nausea, fatigue, skin changes, and altered bleeding patterns.
Additionally, testosterone or DHEA may be used as adjunct therapies and should be carefully personalised according to individual symptoms, medical history, and treatment goals.
Movement as Medicine During Perimenopause & Menopause
Physical activity is one of the most powerful and evidence-based interventions available to support women throughout perimenopause and menopause. As hormone levels fluctuate and decline, movement becomes increasingly important for maintaining metabolic health, preserving muscle and bone mass, supporting cardiovascular function, regulating mood, improving sleep quality, and enhancing overall quality of life.
Oestrogen, progesterone, and testosterone all play important roles in muscle maintenance, bone density, insulin sensitivity, recovery, and nervous system regulation. As these hormones change, many women notice shifts in body composition, reduced strength, increased fatigue, poorer recovery, and changes in mood and energy levels. Regular movement can help mitigate many of these effects and support long-term health outcomes.
However, not all exercise is beneficial for every woman at every stage of the menopausal transition. During perimenopause in particular, fluctuating hormones can influence stress resilience, recovery capacity, blood glucose regulation, and energy availability. What worked in a woman's twenties or thirties may no longer feel supportive.
Many women find themselves exercising harder while seeing fewer results. During perimenopause, hormonal fluctuations, poor sleep, increased life stress, and changing recovery capacity can alter how the body responds to exercise. Strategic strength training, adequate recovery, and nervous system regulation are often more beneficial than simply increasing exercise volume or intensity.
At LITHE Movement, we believe movement should be personalised, purposeful, and aligned with an individual's physiology, symptoms, goals, and lifestyle. Rather than following generic exercise recommendations, we help women build sustainable movement practices that support hormonal health and long-term wellbeing.
Research consistently demonstrates that resistance training should form a key component of exercise during perimenopause and menopause due to its benefits for muscle mass, bone density, metabolic health, and healthy ageing. While individual needs vary, many women benefit from incorporating strength training 2-4 times per week, regular cardiovascular activity, daily movement such as walking, and restorative practices that support recovery and nervous system regulation.
A well-rounded movement approach may include:
• Strength training to preserve muscle mass, support bone density, improve insulin sensitivity, and maintain metabolic health.
• Pilates and functional movement to enhance posture, mobility, core strength, pelvic floor function, body awareness, and movement quality.
• Cardiovascular exercise to support heart health, mitochondrial function, circulation, and energy production.
• Restorative movement practices to support nervous system regulation, stress resilience, recovery, and emotional wellbeing.
The goal is not simply to burn calories or change appearance. Movement becomes a powerful tool for supporting hormonal balance, metabolic resilience, confidence, strength, longevity, and quality of life.
