What Is Perimenopause? Signs, Symptoms and When It Starts
Perimenopause is the natural transition leading up to menopause, when your hormones begin to fluctuate and your periods start to change. For most women in the UK it begins in their mid-to-late 40s, although some notice the first signs in their late 30s. It can last anywhere from a few months to around ten years, and it looks different for every woman.
If you’ve been feeling “not quite yourself” lately, you’re far from alone. Let’s walk through what’s happening, what to look out for, and how you can support yourself.
Discover how EstroPro by USANA can support your wellbeing through every stage of life. In this video, we share how this carefully formulated supplement is designed to complement a balanced lifestyle, particularly during the transition into perimenopause and menopause.
What Is Perimenopause, Exactly?
The word simply means “around menopause”. During this phase, your ovaries gradually release eggs less predictably, and levels of oestrogen and progesterone begin to rise and fall rather than following their usual monthly rhythm.
Think of it less like a switch being flicked off and more like a dimmer being turned down, unevenly, over several years. That unevenness is why symptoms can come and go, and why one month can feel completely different from the next.
When Does Perimenopause Start?
There’s no fixed starting date. Most women begin to notice changes between the ages of 45 and 50, but it’s perfectly normal for it to start earlier or later.
Perimenopause ends when you’ve gone twelve consecutive months without a period. That milestone is what we call menopause, and the average age in the UK is around 51.
A few things can influence when your own transition begins:
- Family history, as your mother’s experience can offer clues
- Smoking, which is linked to an earlier transition
- Chronic stress and long-term nutritional gaps
- Certain medical treatments or surgeries
Common Signs and Symptoms of Perimenopause
There are more than 30 recognised symptoms, and you won’t necessarily experience them all. Here are the ones women mention most often.
Changes to Your Periods
This is often the very first sign. Your cycle might become shorter, longer, lighter, heavier or simply unpredictable. You may skip a month, then have two close together.
Hot Flushes and Night Sweats
A sudden wave of heat through your face, neck and chest, sometimes followed by a chill. At night, these can leave you waking up damp and unsettled.
Sleep, Mood and Mental Clarity
Many women say this is the hardest part, partly because it’s so easy to blame yourself rather than your hormones. You might notice:
- Trouble falling or staying asleep
- Feeling anxious, tearful or short-tempered for no obvious reason
- “Brain fog”, such as losing words or forgetting why you walked into a room
- Persistent tiredness that a good night’s sleep doesn’t fix
Body Changes You Might Not Expect
Perimenopause can also show up in quieter ways:
- Aching joints and muscles
- Headaches or migraines
- Heart palpitations
- Vaginal dryness and a lower libido
- Dry skin and thinning hair
- Weight gathering around the middle
- Bloating and digestive changes
If several of these sound familiar, it’s worth jotting them down in a notebook or phone note. Patterns are far easier to spot, and to discuss with a practitioner, when you’ve tracked them.
Perimenopause vs Menopause: What’s the Difference?
People often use the two words interchangeably, but they’re different stages.
Perimenopause is the lead-up. You’re still having periods, even if they’re irregular, and symptoms are often at their most changeable.
Menopause is a single point in time: twelve months after your last period.
Postmenopause is everything that follows, and for many women, symptoms gradually settle during this stage.
Supporting Yourself Naturally Through Perimenopause
Your body isn’t broken. It’s going through a major life transition, and it responds well to kindness, nourishment and consistency. These everyday habits can make a real difference to how you feel.
Eat to Steady Your Energy
Blood sugar swings can amplify mood dips, cravings and fatigue. Build your plate around whole foods: plenty of colourful vegetables, quality protein, healthy fats and fibre.
Foods such as flaxseeds, chickpeas, lentils and organic soya contain plant compounds that may gently support hormone balance. Magnesium-rich foods like leafy greens, pumpkin seeds and almonds are also worth adding. Many women find that easing off caffeine, alcohol and sugary snacks helps calm hot flushes and improve sleep.
Move in Ways That Feel Good
Regular movement supports your mood, bones and energy. Aim for a mix of brisk walking, strength training and gentle stretching or yoga. Strength work becomes especially valuable at this stage, as it helps protect muscle and bone density.
Calm Your Nervous System
Stress can make almost every perimenopausal symptom feel louder. Even ten minutes of deep breathing, meditation or quiet time with herbal tea can help your body shift out of “fight or flight”. Little and often works better than one big effort.
Protect Your Sleep
A cooler bedroom, breathable cotton nightwear and a consistent bedtime routine can all help. Try switching screens off an hour before bed and keeping your evening meal on the lighter side.
Some women also explore targeted nutritional support, but it’s always best to speak to a qualified practitioner first so that anything you take is right for you.
When to Speak to a Professional
Perimenopause is natural, but you shouldn’t have to simply put up with symptoms that are affecting your quality of life. Make an appointment with your GP or a qualified practitioner if you notice:
- Very heavy bleeding, bleeding between periods or bleeding after sex
- Symptoms that disrupt your work, relationships or daily life
- Persistent low mood or anxiety
- Any changes that worry you or simply don’t feel right
It’s also worth remembering that other conditions, such as thyroid imbalances, can mimic perimenopause, so getting properly checked offers peace of mind.
Most women start perimenopause, which leads to menopause, in their mid-to-late 40s, although some notice the first signs from around the age of 40.
A Gentler Way to See This Chapter
Perimenopause isn’t the end of anything. For many women, it becomes a turning point, a prompt to slow down, listen to their body and finally put their own wellbeing higher on the list.
Start small. Choose one habit from this article, whether that’s a new breakfast, an evening walk or five quiet minutes before bed, and build from there. Your body will thank you for it.
