Female Hormones Explained: What They Do, Hormonal Changes & How to Support Your Health

Feeling tired. Sleeping badly. Feeling more emotional before your period. Noticing your appetite change. Suddenly getting spots. Finding that your periods are different from what they used to be.

Spend five minutes online searching any of thesehttps://mail.google.com/mail/u/1/?hl=en-GB#inbox/FMfcgzQhVrDqmzgKMJCQwsFcdkqtFFlg experiences and there is a good chance you will come across the same explanation:

“Your hormones are out of balance.”

But women’s hormones are far more complex — and far more interesting — than that.

Hormones are supposed to change. They fluctuate throughout the menstrual cycle, respond to what is happening within the body and change significantly during different stages of life.

Understanding those changes can help you become more aware of your body without assuming that every symptom means something is wrong.

Quick Summary

• Hormones are chemical messengers that help regulate many processes throughout the body.

• Oestrogen and progesterone are important reproductive hormones, but women also produce testosterone and rely on hormones including insulin, cortisol and thyroid hormones.

• Hormone levels naturally change throughout the menstrual cycle and across different stages of life.

• “Hormonal imbalance” is a broad phrase, not one single medical diagnosis.

• Tiredness, acne, weight changes, irregular periods, hair changes, poor sleep and mood changes can have many possible causes.

• Healthy everyday habits can support general health and normal body function, but they cannot necessarily correct an underlying hormonal disorder.

• Persistent, unusual or concerning changes are worth discussing with your GP.

What Are Hormones?

Hormones are chemical messengers produced by glands and tissues around the body.

They travel through the bloodstream and communicate with different organs and tissues, helping regulate processes including reproduction, metabolism, growth, stress responses, blood glucose, sleep and many other functions.

The network of glands that produces many of these hormones is known as the endocrine system.

Although we often hear phrases such as “female hormones”, women do not have a completely separate collection of hormones from men. Hormones including oestrogen, progesterone and testosterone are present in both sexes, although their levels, patterns and physiological roles differ.

Key Hormones in Women’s Health

These are only some of the hormones involved in women's health. Others, including follicle-stimulating hormone (FSH) and luteinising hormone (LH), play important roles in ovulation and the menstrual cycle.

How Female Hormones Naturally Fluctuate

Your hormone levels are not designed to remain identical from Monday to Sunday — or from your twenties to your fifties.

They can change with:

• the menstrual cycle

• pregnancy and after pregnancy

• breastfeeding

• age

• perimenopause and menopause

• some medicines and hormonal contraception

• certain health conditions

This distinction matters.

A normal hormonal fluctuation is not the same thing as a hormonal disorder.

And experiencing a symptom that can occur alongside hormonal changes does not tell you, by itself, what is causing that symptom.

Hormones and the Menstrual Cycle

The menstrual cycle involves a coordinated pattern of hormonal changes.

A cycle is often described as being around 28 days, but there is natural variation. The NHS notes that periods commonly occur every 21 to 35 days.

Here is the simplified picture:

Some women notice changes in mood, appetite, breast tenderness, bloating or energy at particular points in their cycle; others notice very little.

PMS is thought to be linked to changing hormone levels during the menstrual cycle, but symptoms and their severity vary considerably between women.

So you do not need to feel a particular way during each “cycle phase” simply because social media says you should.

What Does “Hormonal Imbalance” Actually Mean?

This may be the most important part of this guide.

“Hormonal imbalance” is a broad, non-specific phrase rather than one single medical diagnosis.

There are genuine medical conditions involving too much or too little of particular hormones. Examples include thyroid disorders and conditions affecting insulin or reproductive hormones.

But the phrase “hormonal imbalance” is often used online much more loosely.

You might see symptom lists containing:

• tiredness

• acne

• irregular periods

• hair thinning or increased hair growth

• weight changes

• mood changes

• difficulty sleeping

• appetite changes

The problem is that these experiences can have many different causes.

For example, irregular periods may be associated with stress, significant weight changes, pregnancy, hormonal contraception, perimenopause, excessive exercise, thyroid problems or PMOS/PCOS.

A symptom checklist therefore cannot tell you that your hormones are “out of balance” — or tell you which hormone might be involved.

Can Hormones Affect Mood, Sleep, Appetite and Energy?

Mood

Hormonal changes can interact with emotional wellbeing.

Some women experience mood changes as part of PMS, while low mood, anxiety and mood changes can also occur during perimenopause and menopause.

But mood is influenced by far more than hormones alone, including sleep, stress, relationships, life circumstances and mental health.

Sleep

Hormonal transitions can affect sleep too.

For example, night sweats and other symptoms during perimenopause can make it harder to sleep, and poor sleep itself can then affect mood and how you feel during the day.

Appetite and energy

Hormones participate in the complex systems that regulate appetite, blood glucose, metabolism and energy use.

But feeling hungry or tired does not automatically mean you have a hormonal disorder.

Sleep, meal patterns, nutrition, activity, stress, medicines and health conditions can all influence how energetic or hungry you feel.

Stress and Hormones

Stress and hormones certainly interact — but cortisol deserves better than its reputation as a hormone we need to eliminate.

Cortisol is essential for normal physiology. Problems arise when we reduce an extremely complicated stress-response system to viral claims such as “cortisol belly” or assume that every symptom of stress proves our cortisol is abnormal.

What About Digestion?

Some women notice digestive changes around their menstrual cycle or during different life stages.

But bloating, constipation, diarrhoea and abdominal discomfort have many possible explanations and should not automatically be labelled as hormonal.

Perimenopause and Menopause

Perimenopause is a natural transition towards menopause during which hormone levels change and periods may become irregular.

Menopause is reached when periods have stopped for 12 months, when hormonal contraception is not affecting them. It most commonly occurs between 45 and 55, although it can happen earlier.

Women may experience changes including:

• irregular or changing periods

• hot flushes

• night sweats

• sleep difficulties

• mood changes

• problems with concentration or memory

• vaginal dryness

• changes in sexual desire

Experiences vary enormously. Some women have symptoms that significantly affect daily life, while others experience relatively few.

Perimenopause is therefore an important hormonal transition — not evidence that your body has somehow failed to “balance” itself.

Everyday Habits That Support Overall Hormonal Health

There is no universal food, supplement, tea or morning routine that can “balance all your hormones”.

A more useful approach is to support your overall health.

NHS advice around menopause similarly emphasises balanced eating, regular exercise, rest and looking after mental wellbeing.

A Founder Perspective

At Naya Self Care, I believe wellness should be something you can realistically live with. It doesn't need to mean cutting out entire food groups, following every trend or trying to create a “perfect” body.

Over the years, one of the most interesting parts of building Naya Self Care has been hearing women talk so openly about their wider wellbeing.

Some customers have told us about changes they noticed while KAWA was part of their routine — including periods returning after being absent, changes in menstrual flow, cycles becoming more regular and changes in their skin or acne. We have also heard deeply personal stories from women living with PCOS, as well as customers who later became pregnant and chose to share that part of their journey with us.

Those stories mean a great deal to me as a founder, but they are individual experiences. Periods, fertility, skin and conditions such as PCOS are influenced by many factors, and KAWA should not be considered a treatment for hormonal, menstrual or fertility problems.

For me, that distinction matters. KAWA is a warming herbal drink that some women choose to include as one part of their wider wellness routine — alongside nourishing food, movement, rest and other sustainable habits.

If your periods have stopped, become unusually heavy or changed significantly, or if you have concerns about fertility, PCOS or other hormonal symptoms, please speak to your GP or an appropriate healthcare professional rather than relying on a wellness product to address them.

Hormone Myths Worth Leaving Behind

MYTH: Every unexplained symptom means your hormones are imbalanced.
No. Many symptoms associated online with hormones can have numerous causes.

MYTH: Women need to “balance” their hormones every day.
Hormones naturally fluctuate. Constant levels would not represent normal menstrual physiology.

MYTH: One diet, supplement or drink can balance all your hormones.
There is no universal intervention that does this. Specific hormonal disorders require appropriate assessment and treatment.

MYTH: You can diagnose a hormone problem from social media symptoms.
A symptom list cannot replace medical history, appropriate examination or testing where clinically indicated.

When Should You Speak to Your GP?

You know what is normal for your own body.

Consider speaking to your GP if you notice persistent or significant changes such as:

• your usual period pattern changing

• periods becoming persistently irregular

• bleeding between periods

• periods lasting longer than seven days

• missing three periods in a row when you are not pregnant

• symptoms affecting your everyday life

• possible menopause symptoms, particularly if you are under 45

• new symptoms that concern you

The NHS specifically recommends seeking medical advice for several of these menstrual changes.

And any vaginal bleeding after menopause should be checked by a GP, even if it happens only once.

Key Takeaways

Hormones are essential chemical messengers — not enemies that need to be constantly controlled.

They naturally change throughout the menstrual cycle and across different stages of a woman's life.

Some health conditions genuinely involve abnormal hormone levels or hormone function, but tiredness, weight changes, acne, poor sleep or mood changes alone cannot diagnose them.

Look at your health as a whole, notice meaningful changes and seek professional advice when something persistent or unusual is happening.

Frequently Asked Questions

What are the main female hormones?

Oestrogen and progesterone are major reproductive hormones, but women also produce testosterone and depend on many other hormones including insulin, cortisol and thyroid hormones. Calling all of these “female hormones” oversimplifies how the endocrine system works.

What are signs of hormonal imbalance in women?

There is no universal list that proves someone has a hormonal imbalance. Changes in periods, skin, hair, mood, sleep, weight or energy can sometimes occur with hormonal conditions, but they can also have many other causes.

Can hormones affect your mood?

Yes. Hormonal changes can interact with mood, including around the menstrual cycle and during perimenopause. However, mood is influenced by many biological, psychological and social factors.

Do women produce testosterone?

Yes. Testosterone is present in women as well as men and has several physiological roles.

Can I balance my hormones naturally?

“Balancing hormones” is often used as a wellness phrase, but there is no single diet or lifestyle routine that balances every hormone. Healthy habits can support overall wellbeing and normal body function. Suspected hormonal disorders should be discussed with an appropriate healthcare professional.

A Gentle Reminder

Your body is not supposed to remain hormonally identical every day of the month or throughout every stage of your life.

Normal hormonal change is part of being human.

You do not need to fear every fluctuation, diagnose yourself from a social-media checklist, remove foods unnecessarily or chase every new “hormone balancing” trend.

Learn what is normal for your body. Build sustainable habits. Pay attention when something meaningfully changes.

And when symptoms are persistent, unusual or affecting your quality of life, seek professional advice rather than blaming yourself — or your hormones.
