Perimenopause.

Perimenopause is the natural transition leading up to menopause. During this time, hormone levels fluctuate and women may notice changes in their menstrual cycle, physical health, mood and overall wellbeing.

While many people associate perimenopause with hot flushes, the reality is that symptoms can be far more varied and often begin years before periods stop completely.

For some women, symptoms are mild. For others, they can significantly impact quality of life, work, relationships and sleep.

Understanding what is happening to your body can help you navigate this transition with confidence and access support when needed.

What is Perimenopause?

Perimenopause literally means "around menopause."

It is the period of hormonal change that occurs before menopause, when the ovaries gradually produce less oestrogen and ovulation becomes less predictable.

Perimenopause may begin several years before menopause and often starts in a woman's 40s, although some women experience symptoms earlier.

Menopause is defined as 12 consecutive months without a menstrual period. The years leading up to this are known as perimenopause.

Common Symptoms of Perimenopause

Every woman's experience is different.

Common symptoms include:

Changes in Menstrual Cycles

One of the earliest signs of perimenopause is a change in periods.

You may notice:

• heavier periods

• lighter periods

• shorter cycles

• longer cycles

• irregular bleeding

• missed periods

Hot Flushes and Night Sweats

Many women experience episodes of sudden warmth, flushing or sweating, particularly at night.

Sleep Disturbance

Difficulty falling asleep, waking overnight or feeling unrefreshed despite adequate sleep are common.

Mood Changes

Hormonal fluctuations can contribute to:

• anxiety

• irritability

• low mood

• feeling overwhelmed

• reduced resilience to stress

Brain Fog

Many women describe difficulties with concentration, memory or mental clarity.

Fatigue

Persistent tiredness is a common but often overlooked symptom.

Vaginal and Bladder Symptoms

Declining oestrogen levels may contribute to:

• vaginal dryness

• discomfort during sex

• recurrent urinary tract infections

• urinary urgency or frequency

Reduced Libido

Changes in sexual desire are common and often multifactorial.

How is Perimenopause Diagnosed?

For most women, perimenopause is diagnosed based on symptoms and changes in menstrual cycles.

Blood tests are not always necessary.

Hormone levels fluctuate significantly during perimenopause and a single hormone test may not accurately reflect what is happening.

In some situations, additional investigations may be recommended to exclude other causes of symptoms.

Do I Need Hormone Testing?

This is one of the most common questions women ask.

In women over 45 years of age with typical symptoms, hormone testing is often not required.

Your symptoms and menstrual history are usually more informative than a single blood test.

However, testing may be appropriate in some circumstances, particularly if symptoms occur at a younger age or another condition is suspected.

Is It Just Perimenopause?

Not every symptom experienced during your 40s is automatically caused by perimenopause.

Conditions such as:

• thyroid disorders

• iron deficiency

• sleep disorders

• anxiety and depression

• abnormal uterine bleeding

• fibroids

can cause similar symptoms and sometimes coexist with perimenopause.

This is why a comprehensive assessment can be helpful.

Treatment Options

There is no single "right" way to manage perimenopause.

Treatment depends on symptoms, medical history and personal preferences.

Lifestyle Measures

Many women benefit from:

• regular exercise

• strength training

• adequate sleep

• stress management

• a balanced diet

• limiting alcohol and smoking

Menopause Hormone Therapy (MHT)

Menopause hormone therapy (previously known as HRT) can be highly effective for symptoms such as:

• hot flushes

• night sweats

• sleep disturbance

• mood changes

• vaginal symptoms

Not every woman requires hormone therapy, but it can be life-changing for some.

Vaginal Oestrogen

For women experiencing vaginal dryness, recurrent urinary tract infections or discomfort during sex, local vaginal oestrogen can be highly effective.

Managing Heavy or Irregular Bleeding

Changes in bleeding patterns are common during perimenopause.

Treatment options may include:

• the Mirena intrauterine device

• hormonal medications

• tranexamic acid

• other medical therapies depending on the underlying cause

Perimenopause and Contraception

It is important to remember that pregnancy can still occur during perimenopause.

Women may still require contraception until menopause is confirmed.

Some contraceptive options, including the Mirena, may provide both contraceptive and symptom-management benefits.
