Perimenopause: More Than Hot Flushes
Updated: 6 days ago
How this hormonal transition can show up and why a single hormone test rarely tells the whole story
Many women associate menopause mainly with hot flashes and the absence of menstruation. However, hormonal changes often begin earlier, during perimenopause.
During this transition, many women continue to have their periods. At the same time, their cycle, sleep, mood, concentration, physical wellbeing and sexuality may change. Some changes are initially non-specific and may therefore not immediately be associated with perimenopause.
What is perimenopause?
Perimenopause refers to the transition period before menopause. During this phase, ovarian function changes and hormone production begins to fluctuate more significantly. This phase can last for several years.
Menopause itself is reached only when a woman has had no menstrual period for twelve months and there is no other cause for the absence of menstruation. Perimenopause therefore begins considerably earlier.
How can perimenopause show up?
Symptoms and changes vary from woman to woman. They may include:
a shorter, longer or irregular cycle
heavier or lighter bleeding
hot flushes and night sweats
difficulty falling asleep or staying asleep
fatigue
mood changes or increased irritability
difficulty concentrating or “brain fog”
headaches or changes in existing migraines
breast tenderness
joint or muscle discomfort
vaginal dryness and irritation
pain during sex
changes in desire, arousal or orgasm
Not every woman experiences all of these changes. Some have few symptoms, while others experience a significant impact on their everyday life, work, relationships or sexuality.
What matters is not whether a woman fits a particular idea of what perimenopause should look like. What matters is how she feels and whether she is experiencing distress.
Not every change is automatically hormonal
Many possible symptoms of perimenopause are non-specific. Sleep problems, fatigue, mood changes or changes in libido can also have other physical, psychological or social causes.
Depending on the individual situation, conditions such as thyroid disorders, iron deficiency, medication, chronic stress, depression, sleep disorders or other gynecological conditions may play a role.
A careful medical assessment should therefore identify typical hormonal patterns without overlooking other possible causes.
What does a hormone level tell you?
The desire to have a “hormone panel” is understandable. However, during perimenopause, a single laboratory value often provides only a snapshot. FSH and estradiol in particular can fluctuate significantly over a short period of time.
Laboratory testing can be useful for specific questions, for example in cases of unusually early symptoms, unclear cycle changes or suspected other conditions. Which tests are actually helpful should be decided individually.
A larger laboratory panel does not automatically provide more clarity. What matters is that a test answers a specific medical question.
A good assessment therefore does not begin with a single hormone level. It begins with the woman and her history.
Sexuality can also change
Perimenopause can affect sexuality in different ways. Changes in the vaginal tissues can cause dryness, burning or pain. Lack of sleep, fatigue, mood, stress, medication, body image and relationship circumstances can also affect desire and arousal.
Sexuality, however, is not determined by hormones alone. It develops through the interaction of physical, psychological, relationship and social factors.
Symptoms such as vaginal dryness or pain during sex do not simply have to be accepted as an inevitable part of ageing. Depending on the cause, different local, hormonal, non-hormonal and sexual medicine treatment options are available.
What treatment options are available?
The appropriate treatment depends on the specific symptoms, medical history, possible risks and individual needs.
Possible components may include:
information and counselling
adjustments to sleep, exercise and stress regulation
local treatments for vaginal or vulval symptoms
non-hormonal treatment options
individually assessed menopausal hormone therapy
sexual medicine counselling
pelvic floor physiotherapy
targeted treatment of other physical or psychological causes
Hormone therapy can be an effective option for some women. Whether it is appropriate and which form may be suitable needs to be assessed individually. It is equally important to offer evidence-based alternatives to women who do not want hormonal treatment.
When is medical assessment advisable?
A consultation may be helpful when changes are new, increasing or affecting your quality of life.
Timely gynecological assessment is particularly important in cases of very heavy, unusual or persistent bleeding, bleeding after sex or after menopause, as well as new or significant pain.
