For Patients

You’re not alone in navigating menopause. Learn about the differences between perimenopause and menopause, the symptoms you may experience, ways to support your long-term health, and treatment options that may help you feel your best.

Menopause & Perimenopause

What is menopause?

 

​Menopause marks the end of menstrual cycles and is a natural biological transition caused by the gradual decline in estrogen and progesterone production by the ovaries.​ Menopause is officially confirmed when you have gone 12 consecutive months without a menstrual period, without another medical explanation.​ In Canada, the average age of menopause is approximately 51 years, although natural menopause can occur earlier or later.

 

Menopause occurring:

  • Before age 40 is called premature ovarian insufficiency (POI)

  • Between ages 40 and 45 is considered early menopause

​

Both early menopause and POI deserve medical assessment because earlier loss of ovarian hormones can affect long-term health.

​​

How is menopause diagnosed?​

​

Menopause is usually a clinical diagnosis, meaning your healthcare provider will assess your symptoms and menstrual history.​ In most cases, a blood test is not required. Blood tests such as FSH (follicle-stimulating hormone) and estradiol may sometimes be used when menopause is suspected before age 45, following certain gynecologic surgeries, or when there is uncertainty about the cause of symptoms.

Symptoms

Menstrual changes

 

Changes in menstrual cycles are often one of the first signs of perimenopause. Early in the transition, cycles may become shorter and periods may occur more frequently. Later, cycles often become longer and more irregular, and some periods may be skipped completely. Bleeding may also become heavier or lighter.

 

Worsening PMS

​

Some women notice that previously manageable premenstrual symptoms become more noticeable during early perimenopause. These may include:

  • Bloating

  • Breast tenderness

  • Irritability

  • Mood changes

​

These symptoms are thought to be related to the greater fluctuations in estrogen and progesterone during this stage.

 

Hot flashes and night sweats

​

Hot flashes and night sweats are among the most common symptoms of the menopausal transition. A hot flash is a sudden sensation of intense heat, often beginning in the chest and spreading to the neck and face. It may be accompanied by:

  • Flushing

  • Sweating

  • A rapid heartbeat

 

Night sweats are hot flashes that occur during sleep and may significantly disrupt sleep quality.

​

Sleep disturbances

​

Difficulty falling asleep, waking frequently during the night, and waking feeling unrefreshed are common during perimenopause and menopause. Sleep problems may be worsened by night sweats, although hormonal changes can also affect sleep independently.

​

Mood and anxiety

 

Some women experience:

  • Irritability

  • Low mood

  • Anxiety

  • Increased emotional sensitivity

  • Reduced ability to cope with stress

​

Hormonal fluctuations, sleep disruption, and other changes occurring during midlife may all contribute. Women with a previous history of mood disorders or significant premenstrual symptoms may be more vulnerable to mood changes during the menopausal transition.

​

Brain fog

​

Difficulty concentrating, forgetfulness, and a feeling of mental slowing are frequently described during perimenopause and menopause. These symptoms are often referred to as “brain fog.” For most women, these changes are temporary and tend to improve or stabilize after the menopausal transition.

 

Fatigue

​

Persistent tiredness is common and is often caused by a combination of disrupted sleep, hormonal changes, stress, and the physical and emotional demands of midlife.

 

Joint and muscle pain

 

Joint stiffness, muscle aches, and generalized body discomfort may become more noticeable during perimenopause and menopause. Symptoms may be most noticeable in the morning or after periods of inactivity and may improve with movement.

​

Weight and body composition

 

The menopausal transition is associated with changes in body composition and fat distribution. Fat may increasingly accumulate around the abdomen rather than the hips and thighs. This can occur independently of overall weight gain and is relevant to metabolic and cardiovascular health. Healthy eating and regular physical activity remain important throughout this transition.

Long-Term Effects of Menopause

Why does menopause affect cardiovascular health?

​

Estrogen plays several roles in cardiovascular health, including supporting blood vessel function, cholesterol regulation, inflammation, and blood pressure regulation. As estrogen levels decline, several cardiovascular changes may occur.

 

What changes can occur?

 

Changes associated with menopause may include:

  • Higher LDL cholesterol

  • Changes in other cholesterol levels

  • Increasing blood pressure

  • Greater arterial stiffness

  • Increased accumulation of abdominal fat

  • Changes in metabolic health

 

Subtle changes in the heart and blood vessels may also occur before cardiovascular disease causes noticeable symptoms.

 

Why does timing matter?

 

The years surrounding menopause may represent an important period for cardiovascular prevention. This is a useful time to assess and manage:

  • Blood pressure

  • Cholesterol

  • Blood sugar

  • Smoking

  • Physical activity

  • Nutrition

  • Body composition

  • Other cardiovascular risk factors

​​​

Healthy lifestyle measures and appropriate treatment of cardiovascular risk factors can help protect long-term heart health. Whether menopausal hormone therapy can favorably influence cardiovascular health when started early remains an active area of research and is one of the questions being investigated through the HER BRAVE HEART Trial.

Treatment Options

What is menopausal hormone therapy?

​

Menopausal hormone therapy (MHT) is the most effective treatment available for menopausal vasomotor symptoms, particularly hot flashes and night sweats. It works by replacing some of the estrogen that declines during menopause.

 

Depending on the individual, MHT may improve:

  • Hot flashes

  • Night sweats

  • Sleep disturbances related to menopausal symptoms

  • Vaginal symptoms

  • Other bothersome menopausal symptoms

 

MHT can also help preserve bone density and may play a role in osteoporosis prevention or treatment in appropriately selected women.

​

Estrogen

 

Estrogen is the main component of menopausal hormone therapy. Estradiol is commonly used and is the same form of estrogen produced naturally by the ovaries. It can be given in different ways:

 

  • Transdermal estrogenTransdermal estrogen is delivered through the skin using a patch or gel. Because it enters the bloodstream through the skin rather than first passing through the liver, it has less effect on liver production of clotting factors than oral estrogen. For this reason, transdermal estradiol may be preferred for some women, particularly when cardiovascular or blood-clot risk factors are present.

​

  • Oral estrogen Estrogen can also be taken as a pill. Oral estrogen passes through the liver before entering the circulation and therefore has different effects on clotting and metabolism compared with transdermal estrogen. The most appropriate route depends on your medical history, symptoms, risk factors, and preferences.

​

  • Progesterone - If you still have your uterus, estrogen therapy generally needs to be combined with a progestogen. Estrogen alone stimulates the lining of the uterus and can increase the risk of endometrial cancer over time. Progesterone or another progestogen protects the uterine lining. Women who have had a hysterectomy generally do not require progesterone solely for uterine protection. Micronized progesterone, available as Prometrium® in Canada, is one commonly used option.

 

Who may benefit from MHT?

 

MHT is primarily used to treat bothersome menopausal symptoms, particularly:

  • Hot flashes

  • Night sweats

  • Sleep disruption related to menopausal symptoms

  • Other symptoms affecting quality of life

 

It may also be considered for bone protection in selected women.

 

Who may NOT be able to use systemic MHT?

 

MHT is not appropriate for everyone. Important conditions that require careful assessment include:

  • A personal history of heart attack or stroke

  • A personal history of certain hormone-dependent cancers, particularly breast cancer

  • Active or recent venous thromboembolism, including deep vein thrombosis or pulmonary embolism

  • Unexplained vaginal bleeding

  • Active severe liver disease

  • Certain clotting disorders

​

Your healthcare provider should review your complete medical history before recommending treatment.

 

What do we know about MHT and long-term health?

 

MHT is well established for treating menopausal symptoms and protecting bone health in appropriately selected women. However, MHT has not been definitively proven in randomized clinical trials to prevent cardiovascular disease or increase life expectancy. Research continues to investigate whether the timing, formulation, and route of hormone therapy influence cardiovascular and other long-term health outcomes.

 

An individualized decision

 

MHT is not a one-size-fits-all treatment. The decision to start, continue, modify, or stop hormone therapy should consider:

  • Your symptoms

  • Your age and stage of menopause

  • Your medical history

  • Your cardiovascular risk factors

  • Your bone health

  • Your personal preferences and priorities

 

For women with cardiovascular risk factors or questions about whether hormone therapy is appropriate, the HERA Menopause Clinic can help guide individualized treatment decisions.

Our Research

The HER BRAVE HEART Trial is studying how menopause and menopausal hormone therapy may influence early changes in heart and brain health, with the goal of improving care for women during the menopausal transition.

About the Hormone thERapy Effects on BRAin-HEART Health During the Menopausal Transition (HER BRAVE HEART) Trial

​

Menopause is a universal transition in women’s lives, yet its effects on the heart and brain remain incompletely understood. At the HERA Menopause Clinic, we are conducting the HER BRAVE HEART Trial to better understand how menopause and menopausal hormone therapy may affect early cardiovascular and brain health. The study focuses on symptomatic menopausal women with cardiovascular risk factors and is conducted at the McGill University Health Centre (MUHC) in Montréal.

 

Why this research matters

 

Menopausal symptoms and cardiovascular risk factors frequently occur together. More than 70% of postmenopausal women have at least one cardiovascular risk factor, while up to 80% experience vasomotor symptoms such as hot flashes and night sweats.

 

Despite how often these conditions coexist, important questions remain about whether menopausal hormone therapy is safe, beneficial, or neutral for cardiovascular health in this population. Much of the existing evidence comes from older studies involving women who were many years beyond menopause and who received hormone preparations that differ from those commonly prescribed today.

 

Contemporary transdermal hormone therapy, delivered through the skin using a patch or gel, has not been evaluated in a dedicated randomized cardiovascular trial in this population. Menopause may also represent an important period for brain aging. Hormonal changes during the menopausal transition have been linked to changes in memory, brain metabolism, and other processes involved in cognitive aging. Women account for nearly two thirds of Alzheimer’s disease cases, but the role of menopause in this vulnerability remains an active area of research.

 

The HER BRAVE HEART Trial was designed to begin addressing these important gaps in knowledge.
