What Are Your Hormones Actually Doing? A Plain Guide to the Signs Something Is Off
You've been told your hormones are "fine." Your bloods came back normal. But you're exhausted, your cycle has changed, the belly weight won't shift, and you feel like a different person in the week before your period. Something is off — and you know it.
Here's the thing about hormones: they don't exist in isolation. They are a communication system. When one signal goes wrong, the whole conversation changes. And "normal" on a blood test doesn't mean optimal — it means you're within the range of the average. It says nothing about how your specific body is functioning, or what your symptoms are telling you.
This is the plain guide to what your hormones are actually doing — and what it looks and feels like when they're not.
What Hormones Actually Are
Hormones are chemical messengers produced by glands throughout your body — the ovaries, adrenal glands, thyroid, pancreas, and more. They travel through the bloodstream to target cells, where they switch processes on or off. They regulate your cycle, your sleep, your metabolism, your mood, your stress response, your libido, your digestion, your bone density, and your brain function.
Every system in your body is influenced by hormones. Which is why when something shifts hormonally, the symptoms appear everywhere — not just in one place.
The Hormones That Matter Most for Women
Oestrogen
Your primary female sex hormone. Produced mainly by the ovaries, it rises in the first half of your cycle, supports the uterine lining, maintains bone density, supports skin and hair, regulates mood via serotonin, and keeps the brain sharp. When oestrogen is too low — as in perimenopause — you get brain fog, low mood, dry skin, low libido, and bone loss. When it is too high relative to progesterone (oestrogen dominance), you get heavy periods, breast tenderness, bloating, and belly weight.
Progesterone
Your calming hormone. Produced after ovulation by the corpus luteum, it rises in the second half of your cycle, supports sleep, stabilises mood, buffers cortisol, and prepares the uterus for pregnancy. Progesterone is the first hormone to decline in perimenopause — often years before oestrogen changes significantly. Low progesterone is behind waking at 3am, rage before your period, anxiety that arrives in the luteal phase, and cycles that get shorter.
Cortisol
Your primary stress hormone. Produced by the adrenal glands, cortisol regulates your wake-sleep cycle, mobilises energy under stress, controls inflammation, and influences blood sugar. Chronically elevated cortisol — from sustained stress, poor sleep, or overexercising — drives belly fat storage, disrupts progesterone (the progesterone steal), impairs thyroid function, and depletes the entire hormonal system over time.
Insulin
The hormone that regulates blood sugar. When cells become resistant to insulin — from chronic stress, poor diet, or hormonal imbalance — blood sugar becomes harder to regulate, fat storage increases (particularly around the abdomen), energy crashes, and cravings for sugar and carbohydrates intensify. Insulin resistance and hormonal imbalance are deeply intertwined — each makes the other worse.
Thyroid Hormones (T3 and T4)
Your metabolic hormones. The thyroid regulates how fast your cells work — energy production, metabolism, temperature regulation, heart rate, and mood. Underactive thyroid (hypothyroidism) causes fatigue, weight gain, hair loss, constipation, low mood, and feeling cold. It is significantly more common in women than men and is frequently missed or undertreated because TSH alone is an incomplete picture.
What Hormone Imbalance Actually Feels Like
Not the textbook list — the real one. The things women type into Google at 11pm.
- Waking at 3am with a racing mind and no obvious reason
- Rage or tearfulness in the week before your period that doesn't feel like you
- Cycle getting shorter — 28 days becoming 25, then 22
- Belly weight that appeared and won't shift despite nothing changing
- Exhausted all day, then unable to sleep at night
- Brain fog — losing words, forgetting why you walked into a room
- Hair thinning or falling out more than usual
- Skin becoming drier or breaking out when it never used to
- Periods becoming heavier, more painful, or more irregular
- Low libido with no emotional explanation
- Feeling cold when others are comfortable
- Sugar cravings that feel uncontrollable, particularly in the afternoons
- Anxiety that is new — or significantly worse than before
These are not separate problems. They are different expressions of the same underlying hormonal conversation going wrong.
Why "Normal" Blood Tests Miss the Picture
Standard hormone blood tests measure a single point in time. Hormones fluctuate across your cycle, across the day, and in response to stress. A cortisol test taken at 9am tells you nothing about your cortisol pattern at 3am when you're awake. An oestrogen reading on day 3 tells you nothing about what's happening in your luteal phase. TSH within the "normal" range doesn't mean your thyroid is functioning optimally for you.
This is why symptoms matter as much as numbers. Your body is giving you information that a single blood test cannot capture. The question is whether you — and your practitioners — are reading it.
What Actually Disrupts Hormones
Chronic Stress
The single biggest disruptor for most women. Cortisol steals from progesterone, suppresses thyroid function, drives insulin resistance, disrupts gut bacteria (which affects oestrogen metabolism), and impairs sleep — which then disrupts every other hormone. Stress is not just a lifestyle issue. It is a hormonal cascade.
Poor Sleep
Growth hormone, cortisol, insulin, leptin, ghrelin — all reset during sleep. Consistently poor sleep disrupts each of these, driving cravings, weight gain, mood instability, and accelerating hormonal decline. Sleep is not a luxury. It is the most powerful hormone regulator available.
Blood Sugar Instability
Skipping meals, eating high-sugar foods in isolation, and not including protein and fat at every meal create glucose spikes and crashes that stress the adrenal glands, drive cortisol release, worsen insulin resistance, and amplify every other hormonal imbalance.
Gut Imbalance
The gut microbiome directly regulates oestrogen metabolism via the estrobolome. 90% of serotonin — which influences mood, appetite, and pain — is produced in the gut. When gut bacteria are out of balance, hormones follow.
Environmental Oestrogens (Xenoestrogens)
Plastics, certain pesticides, synthetic fragrances, and some personal care products contain compounds that mimic oestrogen in the body. These add to total oestrogen load and can contribute to oestrogen dominance — particularly when the liver and gut are already struggling to clear oestrogen efficiently.
Where to Start
Not everything at once. Pick one area. Do it for two weeks. Then add another.
- Sleep on time — consistently. The same bedtime every night, aiming to be asleep before 10pm. This alone changes cortisol, melatonin, growth hormone, and insulin.
- Protein at every meal. Protein stabilises blood sugar, supports liver detoxification pathways, and provides the amino acids hormones are built from.
- Eat lunch as your biggest meal. Metabolism and digestion peak mid-day. Front-loading food reduces evening cortisol spikes and improves sleep.
- Move — but match your cycle. High-intensity exercise in the week before your period raises cortisol and worsens symptoms. Walk, do yoga, or do strength work. Save harder sessions for the first half of your cycle.
- Reduce alcohol. Alcohol impairs liver clearance of oestrogen, disrupts sleep architecture, and depletes magnesium — which is essential for progesterone production and sleep.
When to Work With a Practitioner
If your symptoms are significantly affecting your sleep, your mood, your relationships, or your ability to function — that is not something to manage alone with supplements and guesswork. A practitioner who understands the full hormonal picture — across your five systems, not just a single blood panel — can help you identify where the breakdown is happening and build a protocol that addresses the root.

Frequently Asked Questions
How do I know if my hormones are off?
The clearest signals are symptoms that cluster together — waking at 3am, rage before your period, belly weight that won't shift, a cycle that has changed, exhaustion that doesn't respond to rest, brain fog, or hair thinning. Hormonal imbalance rarely shows up as one isolated symptom. It shows up as a pattern across multiple systems simultaneously.
What are the signs of oestrogen dominance?
Oestrogen dominance — too much oestrogen relative to progesterone — typically shows up as heavy or painful periods, breast tenderness before your period, bloating, belly weight, mood swings in the luteal phase, and worsening PMS. It is often driven by gut imbalance (poor estrobolome function), chronic stress, and liver congestion rather than oestrogen being intrinsically too high.
What are the signs of low progesterone?
Low progesterone typically presents as waking at 3am, anxiety or irritability in the week before your period, cycles getting shorter, difficulty staying asleep, and feeling emotionally dysregulated in a way that doesn't match your circumstances. Progesterone is the first hormone to decline in perimenopause — often in the late 30s, years before oestrogen changes significantly.
Can stress cause hormone imbalance?
Yes — and it is the most common driver of hormonal disruption in women under 50. Cortisol and progesterone share a precursor (pregnenolone). Under chronic stress, the body prioritises cortisol production, leaving less available for progesterone. This is called the progesterone steal — and it explains why high-stress periods consistently worsen PMS, sleep, and cycle regularity.
Do I need to test my hormones?
Testing can be useful — particularly Dutch testing (dried urine), which gives a more complete picture of hormone metabolites across the cycle than a single blood draw. However, testing is most valuable when interpreted alongside your symptoms and cycle history by a practitioner who understands the full picture. A "normal" result does not rule out functional hormonal imbalance.
What is the best diet for hormone balance?
There is no single hormone-balancing diet — but the consistent principles are: protein at every meal to support blood sugar and liver detox; cruciferous vegetables for oestrogen clearance; healthy fats for hormone production; fibre for gut health and oestrogen elimination; and minimal processed food, refined sugar, and alcohol. Eating to your cycle — adjusting food types and exercise intensity across your four phases — adds another layer of precision.
Can hormonal imbalance cause anxiety?
Yes — and it is underdiagnosed. Progesterone has a direct calming effect via GABA receptors. Low progesterone removes this natural brake on the nervous system. Thyroid imbalance can drive anxiety and palpitations. High cortisol creates a state of chronic physiological stress. All three are frequently missed when anxiety is treated purely as a psychological issue.
What is the difference between perimenopause and hormone imbalance?
Perimenopause is a specific life stage — the years of hormonal transition before menopause, typically beginning in the late 30s to mid-40s. Hormonal imbalance can occur at any age — driven by stress, gut health, nutrition, environmental factors, or conditions like PCOS or thyroid disease. The symptoms can overlap significantly, which is why working with a practitioner who considers the full picture matters.
