Am I starting menopause at 40? Signs you shouldn’t ignore

Menopause is often thought of as something that happens in your 50s, but for some women, the journey begins much earlier. Experiencing signs of menopause in your 40s - or even late 30s - is not uncommon. This transition, known as perimenopause, marks the time when your body starts to prepare for menopause. For others, menopause itself might arrive early due to genetic factors, medical conditions, or lifestyle influences.

If you’re in your 40s and noticing changes in your body or emotions that feel out of the ordinary, understanding the early signs of menopause can help you navigate this life stage with clarity and confidence.

What is menopause, and why does it happen early?

Menopause is defined as the point when a woman hasn’t had a menstrual period for 12 consecutive months. This typically occurs around age 51, but for some, the signs of menopause can appear much earlier due to a variety of reasons:

• Perimenopause: The transition phase leading up to menopause. This can begin in your late 30s or 40s and last for several years.
• Primary ovarian insufficiency (POI): A condition where the ovaries stop functioning normally before age 40.
• Medical treatments: Surgeries like a hysterectomy or treatments such as chemotherapy can induce early menopause.
• Genetics: If your mother or other close relatives experienced early menopause, you may too.

The subtle (and not-so-subtle) signs

The signs of menopause at 40 can be varied, often mimicking other health issues or even the effects of a busy lifestyle. Here’s how your body might communicate this transition:

Changes in your menstrual cycle

One of the earliest and most telling signs is an irregular period. You may notice:

• Periods that come closer together or further apart.
• Heavier or lighter bleeding than usual.
• Missed periods that aren’t due to pregnancy.

These changes occur because your ovaries are producing less estrogen, which disrupts the balance needed for a regular cycle.

Mood swings and emotional shifts

Ever feel like your emotions are all over the place? Fluctuating hormone levels can impact the neurotransmitters in your brain, leading to:

• Increased anxiety or irritability.
• Periods of sadness or even depression.
• Feeling overwhelmed or less like yourself.

Hot flashes and night sweats

Hot flashes can strike at any age during menopause. You might experience sudden warmth in your face, neck, or chest, often accompanied by sweating or redness. At night, this can lead to interrupted sleep and leave you feeling fatigued.

Sleep disturbances

Speaking of sleep, many women in their 40s report difficulty falling asleep or staying asleep. Hormonal changes, night sweats, or even heightened anxiety can contribute to restless nights.

Changes in libido

A drop in oestrogen and testosterone can result in decreased sexual desire or changes in arousal. This can sometimes feel disorienting, especially if it’s new for you.

Physical changes

You might notice unexpected shifts in your body, such as:

• Weight gain, particularly around the midsection.
• Thinning hair or dry skin.
• Changes in breast tissue, including tenderness or loss of firmness.

Cognitive symptoms

Brain fog, forgetfulness, or difficulty concentrating can feel frustrating and are common signs of hormonal shifts.

How to know if it’s menopause

If you’re experiencing these symptoms in your 40s, it’s essential to consult with your doctor. They may recommend:

• Blood tests: To measure hormone levels and rule out other conditions like thyroid issues.
• Family history review: To see if early menopause runs in your family.
• Lifestyle assessment: To determine if stress, diet, or other factors could be contributing.

* Note: Hormone levels can fluctuate throughout the day and month, so a single blood test may not provide a definitive answer. Your doctor might consider your symptoms alongside test results for a clearer picture.

What you can do

If you’re facing signs of menopause at 40, there’s good news: there are many ways to manage this transition and support your health.

• Lifestyle changes: A healthy diet rich in calcium, vitamin D, and whole foods can help. Regular exercise, especially strength training, supports bone health and reduces stress.
• Stress management: Mindfulness, yoga, or other stress-reduction techniques can improve mood and overall well-being.
• Talk to your doctor: Whether you’re interested in natural supplements, menopause hormone therapy (MHT), or other treatments, discussing your options is key.

Embracing early menopause

Early menopause can feel overwhelming, but it’s also an opportunity to tune into your body and prioritise your health. Understanding the signs and seeking support can help you navigate this phase with confidence.

If you’re noticing symptoms and wondering if they’re related to menopause, trust your instincts and start a conversation with your doctor. It’s never too early - or too late - to take control of your well-being.
