Perimenopause: what happens to your body, and what you can do.
Perimenopause usually begins in the mid to late 40s, earlier for some women. It lasts 2 to 12 years. We help you understand what is happening in your body and what can help.
The transition to menopause, not menopause itself.
Perimenopause is the transition to menopause, the period in which the ovaries gradually reduce their function. Oestrogen swings, rising and falling irregularly, progesterone declines, FSH rises. Menopause itself is confirmed in hindsight, once the last period was twelve months ago.
The average age of menopause in Switzerland is 51. So perimenopause often begins in the mid-40s, sometimes as early as 38.
What becomes noticeable in perimenopause.
From hot flushes to brain fog, from sleep problems to weight gain. One symptom alone says little, the interplay is what matters.
The hormone biology behind it.
Oestrogen regulates far more than the cycle: sleep, mood, metabolism, bone health and the moisture of the mucous membranes. When oestrogen swings and falls, those effects show up throughout the body.
Oestrogen regulates sleep, mood, metabolism, bone and mucous membranes. When it swings and falls, it shows up throughout the body.
Progesterone often falls first, because ovulation is skipped more often. That can contribute to irregular or heavier bleeding.
FSH rises in response to falling oestrogen levels. A lab value that fluctuates widely and is not decisive on its own.
There are good weeks and bad weeks. A single lab value is rarely conclusive, the assessment needs symptoms and course over time.
Often missed: many women first receive a diagnosis of burnout, depression or a thyroid problem before the hormonal cause is recognised. An underactive thyroid can cause similar symptoms and is therefore assessed alongside.
What is medically possible in perimenopause, step by step.
It always starts with a medical initial consultation. What follows depends on your phase and your findings.
Intake questionnaire beforehand, then a 1:1 video consultation. Your physician works out whether your symptoms fit perimenopause or have another cause.
Oestradiol and FSH swing widely in this phase, a single value decides nothing. Lab values are used where they change the plan, and the thyroid is assessed alongside.
A dedicated video consultation: what connects, what is treatable and what is watched.
Closely guided during the setup phase, then on a quarterly rhythm. Dosage and tolerability are reviewed continuously.
Not every patient is suited to every therapy. Treatment decisions are made by your physician, not an algorithm.
To treatmentYour medical assessment
Your initial consultation brings clarity about your next medical step. Where medically indicated, targeted diagnostics complete the assessment. During treatment you are supported by a physician throughout.
Your 1:1 video consultation with your physician, prepared by your intake questionnaire. A personal assessment and a clear recommendation for the next steps.
Follow-up with your physician every month, for phases in which effect, tolerability or dosage need to be guided closely. You can stop at any time, and the current monthly period runs to its end.
Follow-up with your physician every three months, once your treatment is well established. You pay for three months in advance. You can cancel at any time, and the quarterly period you have already paid for runs to its end.
Where medically indicated: targeted diagnostics. Your physician discusses the scope and cost with you beforehand.

All questions and answersWhen does perimenopause begin?
Perimenopause usually begins in the mid to late 40s, but it can start earlier. The first signs are often irregular cycles or changes in bleeding, before hot flushes.
How long does perimenopause last?
The duration varies widely, from 2 to 12 years. On average it is 4 to 5 years.
Is perimenopause the same as menopause?
No. Perimenopause is the transition, the phase of hormonal change. Menopause is confirmed in hindsight, once the last period was twelve months ago.
Can perimenopause be detected with a blood test?
Usually not. From around 45, your physician assesses perimenopause from your symptoms and your cycle, because hormone levels fluctuate too much. A blood test helps mainly in younger women or when another cause such as the thyroid is possible.
Does hormone therapy help with perimenopausal symptoms?
For hot flushes and night sweats, hormone replacement therapy is very effective according to current guidelines, and for many women sleep and mood improve with it, often because the hot flushes ease. Whether it suits you depends on your individual situation, which needs a medical assessment.
