Acne on your chin at 35, a cycle that suddenly goes every which way, or hair thinning for no clear reason. They seem like separate complaints, but they can share the same root: a hormonal imbalance. And it is more common than you think, precisely because hormones play a part in almost every process in your body.
What I like to tell women: an imbalance is rarely one hormone that is "broken", but a team that loses its proportions. That is why a broad picture helps more than zooming in on one value.
What is a hormonal imbalance?
Your body makes dozens of hormones that work together as a team: oestrogen, progesterone, testosterone, cortisol and thyroid hormones. A hormonal imbalance means one or more of these hormones are too high or too low compared to what your body needs. It is not always an extreme deviation; a subtle shift can already be enough to cause complaints.
Causes of a hormonal imbalance
- Chronic stress raises your cortisol, which can affect your other hormones.
- Lack of sleep disrupts the hormone production that happens largely at night.
- Nutrition short of zinc, magnesium or vitamin D can affect the balance.
- Life stage such as puberty, pregnancy and menopause brings natural shifts.
- Thyroid problems affect your entire hormone system.
- Medication, including contraception, can affect your hormonal system.
Which hormones most often fall out of balance?
The table below links the hormones that most often cause complaints in women to their role and to typical signals. Use it to recognise which hormone may fit your story.
| Hormone | Role | Typical signals when disrupted |
|---|---|---|
| Oestrogen | Cycle, bones, mood | Hot flushes, dryness, low mood |
| Progesterone | Second half of cycle | Irregular cycle, sleep problems |
| Cortisol | Stress hormone | Fatigue, belly fat, poor sleep |
| Thyroid (TSH) | Metabolism | Fatigue, weight change |
| Testosterone | Energy, libido | High: acne, hair growth; low: low libido |
Symptoms in women
The signals are varied and sometimes hard to recognise: an irregular or absent period, fatigue that rest does not lift, mood swings, unexplained weight change, skin problems such as acne or dry skin, hair loss or, conversely, excess hair growth, sleep problems and a reduced libido. If you recognise several signals, having your hormone values checked can be worthwhile. The NHG points out that these complaints can have other causes too, so a doctor can help determine the right direction.
What can you do yourself?
Not all hormonal complaints can be solved on your own, but lifestyle often has a positive effect: move regularly and moderately, aim for 7 to 9 hours of sleep in a dark, cool room, eat varied with enough protein, healthy fats and vegetables, limit stress with breathing exercises or walking, and avoid excessive alcohol and caffeine. The Voedingscentrum advises a varied diet with enough vegetables, fruit and wholegrain products as a basis. If complaints persist or worsen, contact your GP.
How an imbalance shows up differently per life stage
What a hormonal imbalance means differs strongly with your age. In your twenties and thirties it more often shows up as an irregular cycle, acne or complaints that fit PCOS. Around forty the picture shifts toward perimenopause: fluctuating oestrogen, worse sleep and mood swings. After menopause it is the permanently low oestrogen that dominates. That same complaint, fatigue for example, can have a different hormonal cause in each phase. That is why it is worthwhile to factor in your age and life stage, and not attribute every complaint to the same hormone.
The difference between fluctuating and being out of balance
Hormones are supposed to fluctuate. Your oestrogen and progesterone rise and fall within every cycle, and that is exactly the intention. Only when those fluctuations systematically disrupt your life, or when values sit structurally too high or too low, do we speak of an imbalance. A single rough week around your period is therefore not the same as a hormonal imbalance. It helps to watch the pattern over several months: do the complaints keep returning, do they get worse, or are they unrelated to your cycle? That distinction determines whether waiting it out makes sense or whether a test and a conversation with your doctor offer more.
When is it wise to test?
A hormone test gives insight into your current values and is worthwhile if you have had complaints for a while that may be hormonal. A blood test can measure, among others, estradiol, progesterone, testosterone, cortisol and TSH. A broad hormones for women test does that in one go. The result is a starting point to discuss steps with a healthcare provider.

Frequently asked questions
How do I know if my hormones are out of balance?
Complaints such as fatigue, mood swings, an irregular cycle or skin problems can point to it. A blood test gives more clarity about your hormone values.
Can stress cause a hormonal imbalance?
Yes, prolonged stress can raise your cortisol, which can affect your oestrogen, progesterone and thyroid hormones. Stress management is therefore an important part of a healthy hormone balance.
How long does it take to rebalance hormones?
That varies per person and depends on the cause. With lifestyle changes you sometimes notice a difference within weeks; with underlying conditions it can take longer and guidance from a doctor is advisable.
