Should I Take HRT? Why Lifestyle Still Matters

HRT can replace estrogen. It can’t replace everything else our bodies need to stay strong and healthy as we age.

If declining estrogen contributes to many of the changes that occur during and after menopause, it seems logical that replacing estrogen would help.

And in many cases, it does.

Hormone Replacement Therapy (HRT), also known as Menopausal Hormone Therapy (MHT), can be an effective treatment for menopausal symptoms and can provide important health benefits, particularly when it comes to maintaining bone health.

However, HRT doesn’t replace the need for strength training, good nutrition, cardiovascular exercise and adequate sleep.

Important: This article provides general information about HRT and menopause and is not intended to replace individual medical advice. Please speak with a healthcare professional experienced in menopause care about whether HRT is appropriate for you.

What Happens When Estrogen Declines?

As estrogen declines during perimenopause and menopause, women may experience changes including:

Hot flushes and night sweats
Sleep disturbances
Vaginal dryness and urinary changes
Accelerated bone loss
Loss of muscle mass and strength
Changes in body-fat distribution
Increased abdominal and visceral fat
Changes in cholesterol
Reduced insulin sensitivity
Increased cardiovascular risk
Joint aches and stiffness
Changes in skin and connective tissue
Mood changes
Brain fog and difficulty concentrating
Fatigue and reduced energy
Changes in blood-vessel function and increased blood pressure

Not every woman will experience all of these changes, and it’s important to recognise that declining estrogen is not the only factor involved.

Ageing, genetics, lifestyle, physical activity, nutrition and other health factors can also play a role.

And that’s an important distinction, because while we can’t control the natural decline in estrogen, many of the other factors are things we can influence.

Where Does HRT Fit In?

HRT is commonly prescribed to treat troublesome menopausal symptoms.

It can also provide other important health benefits, particularly when it comes to bone health. However, replacing estrogen doesn’t return our bodies to their pre-menopausal state or remove the other changes that occur as we age.

Estrogen was never the only thing protecting our health.

Maintaining muscle and strength, cardiovascular fitness, bone health, metabolic health and a healthy body composition also depend on how we move, how we eat, how well we sleep and many other lifestyle factors.

This is why strength training, good nutrition, cardiovascular exercise and adequate sleep remain important – whether we take HRT or not.

HRT Can’t Replace Strength Training

Maintaining muscle, strength and bone becomes increasingly important as we get older.

HRT can help protect against menopause-related bone loss and may have beneficial effects on muscle, but taking estrogen doesn’t provide the physical stimulus our bodies need to become stronger.

Muscle responds to demand.

Progressive resistance training challenges our muscles to adapt, helping us maintain and build muscle and strength as we age.

It’s what allows us to carry groceries, climb stairs, lift a suitcase, get up from the floor, hike up a hill and maintain our physical independence later in life.

Strength training is also important for our bones.

HRT can help reduce the accelerated bone loss associated with declining estrogen, but our bones also respond to mechanical loading.

Resistance training, together with appropriate impact exercise, provides this stimulus while also building the muscle and strength that can help reduce our risk of falls.

As we age, we also tend to lose power – our ability to produce force quickly. This becomes particularly important when we need to react quickly, regain our balance or prevent a fall.

HRT can’t replace the physical stimulus our muscles and bones need to stay strong.

HRT Can’t Replace Cardiovascular Exercise

Our heart, lungs and cardiovascular system need to be trained too.

Regular aerobic exercise improves cardiovascular fitness and can help lower blood pressure, improve blood glucose control and insulin sensitivity, and reduce our risk of developing cardiovascular disease and type 2 diabetes.

This becomes increasingly important after menopause, when cardiovascular risk increases with age and changes in estrogen can also affect cholesterol, blood vessels and where we store body fat.

Cardiovascular exercise also provides benefits for our brain, mood and sleep, while helping us maintain the fitness we need to remain active and independent as we get older.

HRT may have beneficial effects on some cardiovascular and metabolic factors, but it doesn’t provide the adaptations that occur when we regularly challenge our heart and lungs.

HRT can’t replace the cardiovascular benefits of exercise.

HRT Can’t Replace Good Nutrition

Replacing estrogen doesn’t stop the ageing process.

Even with HRT, we still need to address the age-related changes occurring in our muscles, bones, cardiovascular system and metabolic health.

As we get older, maintaining muscle becomes increasingly important, making adequate protein a priority.

Calcium, vitamin D and protein help support bone health, while fibre, healthy fats, fruit, vegetables and wholegrains support cardiovascular, gut and metabolic health.

Good nutrition also plays an important role in maintaining a healthy body composition and reducing the accumulation of visceral fat, which is associated with increased cardiovascular and metabolic risk.

HRT can’t replace the nutrients our bodies need to stay strong and healthy as we age.

HRT Can’t Replace Good Sleep

HRT may improve sleep for some women, particularly when hot flushes and night sweats are causing sleep disturbances.

But replacing estrogen doesn’t guarantee good-quality sleep.

Stress, alcohol, caffeine, lifestyle habits and our sleep environment can all affect how well we sleep.

Adequate sleep remains important as we age, supporting recovery, mood, appetite regulation, metabolic health, cognitive function and our ability to train and maintain muscle.

HRT may help us sleep better, but it can’t replace the health benefits of actually getting enough quality sleep.

HRT and Lifestyle Aren’t Competitors

None of this means HRT isn’t valuable or that menopausal symptoms should be managed through lifestyle alone.

HRT and lifestyle have different roles.

HRT can be an effective treatment for menopausal symptoms, while strength training, cardiovascular exercise, good nutrition and sleep provide benefits that HRT cannot replace.

Whether or not we choose to take HRT, these lifestyle factors remain important for our long-term health.

Lifestyle isn’t a replacement for HRT when HRT is needed to treat menopausal symptoms. And HRT isn’t a replacement for lifestyle when it comes to protecting our long-term health.
