Complete guide
Menopause symptoms: the guide to finally make sense of it all.
Group by group, everything perimenopause and menopause can change — at what age, for how long, and where to start.
In short
- Perimenopause can start years before your last period; menopause is 12 months without one.
- Symptoms go far beyond hot flashes: sleep, mood, brain fog, joints, skin, cycle.
- They're hard to make sense of because they come and go, and overlap.
- A simple daily log is the first useful step, and helps your doctor too.
Sleep that breaks, fatigue that sticks, words that escape you, a mood that shifts without warning… Taken one by one, these things seem unrelated. That's exactly the trap: nobody shows you the big picture.
This guide does. Not to worry you — but to give you what's most missing at this stage: clear wordsfor what you're going through, and an order in which to look at it.

Perimenopause, menopause: what are we talking about exactly?
Menopause, officially, is a milestone: 12 months in a row without a period. But symptoms often start years before, during perimenopause— the phase when progesterone drops first and estrogen becomes erratic. It's this instability, more than the drop itself, that explains most of the signs.

Symptoms, group by group
You probably won't have all of them — every woman has her own combination, at her own intensity. What matters is recognizing your picture.
Sleep
Often the first domino to fall — and the one that knocks over the others.
- Waking up in the middle of the night, often around 3–4 am, with a racing mind.
- Night sweats that jolt you out of sleep.
- Harder time falling asleep, a feeling of "light" sleep.
Energy
A different kind of fatigue than before: rest doesn't make it go away.
- Waking up already tired, as if the night did nothing.
- The afternoon crash that coffee no longer fixes.
- Your drive fading: even things you love take huge effort.
Mind and mood
Estrogen also acts in the brain — these signs are physiological.
- Brain fog: words escaping you, weaker focus, forgetfulness.
- New irritability or anxiety, for no obvious reason.
- Mood on a roller coaster, and that feeling of "not recognizing yourself."
Body
Your internal thermostat and metabolism go off track along with your hormones.
- Hot flashes rising from your chest to your face, day and night.
- Heart palpitations, stiffer joints, headaches.
- Drier skin and hair, a body shape that changes even though your habits haven't.
Cycle and intimacy
The most "visible" signs — and yet rarely explained.
- Irregular periods: closer together, further apart, heavier or almost absent.
- Vaginal dryness, new discomfort, a changing libido.
- Needing to pee more often, small leaks when you exert yourself.
Why it's so hard to make sense of it
Because symptoms fluctuate — one good week, then two bad ones — and they often show up beforeyour periods really change. So you look elsewhere: stress, work, age. And you're told "it's normal," with no explanation.
Yet you're far from an isolated case — and none of this is "in your head."

When should you see a doctor?
As soon as symptoms weigh on your daily life: your doctor or OB-GYN can do a lot — including talking you through treatment options if they're right for you. And see them right away in case of unusual bleeding (very heavy, between periods, or after your periods have stopped). Good news along the way: in most cases, no blood test is needed — diagnosis is based on age and symptoms.
The first useful step: track what you're going through
With symptoms that fluctuate, your memory is a poor ally: you remember last night's bad sleep, not the pattern of the last three weeks. Writing down each day what you're going through — sleep, energy, mood, hot flashes — changes everything: you see what comes back, when, and after what. It's also the best foundation for a useful appointment with your doctor.
That's exactly what Menolys does: a few minutes a day to track your symptoms, understand what triggers them, and move forward with a personalized 6-month program— with Camille, your AI coach, by your side. Let's be clear: Menolys is not a medication and doesn't replace your doctor. It helps you see clearly— and that's already huge.
FAQ
What women ask the most
At what age do the first symptoms start?
On average around 47, with perimenopause — the transition before periods stop. Menopause itself happens at 51 on average, but every woman has her own timeline: before 45 or after 55 happens too.
Do I need a blood test to confirm menopause?
In most cases, no. Menopause is recognized from age and symptoms — officially, after 12 months in a row without a period. Most women don't need a hormone test; your doctor will tell you if one is useful in your situation.
How long do symptoms last?
Perimenopause usually lasts 2 to 4 years. Some symptoms, like hot flashes, can continue for years after periods stop — up to 14 years according to the US Office on Women's Health. Length and intensity vary hugely from one woman to another, which is why tracking your own picture matters.
Does every woman have symptoms?
Almost: in French data from Inserm, 87% of women have at least one symptom in addition to their periods stopping, and 20 to 25% have symptoms severe enough to affect daily life. If that's you, you're not fragile, and you're not an exception.
When should I see a doctor?
As soon as symptoms weigh on your daily life — sleep, mood, work, relationships. And right away in case of unusual bleeding (very heavy, between periods, or after menopause): your doctor or OB-GYN is the right call.
