What is a hormone imbalance? (And what it actually looks like in your body)

19 June

"I think my hormones are imbalanced" is one of the most common things I hear in clinic. But the phrase gets thrown around so often that most people don't actually know what it means.

So let's break it down properly.

What a hormone imbalance actually is

Your hormones aren't meant to sit at one fixed level. They're meant to rise and fall in a pattern, day to day and across your cycle. Oestrogen climbs before ovulation, progesterone rises after it, and the two work together like a seesaw to keep everything from your mood to your sleep to your metabolism running smoothly.

A hormone imbalance is what happens when that pattern breaks down. It might mean one hormone is too high or too low. More often, it means the ratio between hormones has shifted, even when individual levels look "normal" on paper. That's why a standard blood test can come back fine while you still feel completely off.

This is also why the same words "hormone imbalance" can describe very different pictures depending on your stage of life:

In PCOS (now known as PMOS), the pattern usually involves excess androgens and irregular or absent ovulation, which throws off the normal oestrogen-progesterone rhythm.
In perimenopause, ovulation becomes less consistent, progesterone drops first and faster than oestrogen, and the resulting gap is what drives a lot of the classic symptoms.

Each condition has a completely different mechanism. That's why "balance your hormones" generic advice rarely works. You need to know which pattern you're actually dealing with.

Understanding your hormone cycle

Drag the slider to move through a typical 28 day cycle and see how oestrogen, progesterone and your other key hormones shift day to day. You can also overlay how a PCOS or perimenopause pattern can look different.

How PCOS can change this picture

The dashed line shows one common PCOS pattern: oestrogen rising but without a clear LH surge, so ovulation doesn't reliably happen. Progesterone then stays low because there's no corpus luteum to produce it.

PCOS presentations vary a lot between individuals. Some people ovulate irregularly, some rarely ovulate, and cycle length can range from a few weeks to several months. This overlay is a simplified example, not a diagnostic picture.

Often longer, less predictable cycles
Lower progesterone overall due to infrequent or absent ovulation
Common features: irregular bleeding, acne, excess hair growth, weight changes

Tip: switch on "show LH & FSH" above to see how the LH surge is flattened in this pattern.

How perimenopause can change this picture

The dashed line shows a typical perimenopause pattern: oestrogen becomes erratic (often spiking higher before declining), progesterone trends lower as ovulation becomes less consistent, and cycle length and timing shift month to month.

This is a general pattern, the timing and intensity of these shifts is highly individual and can change from cycle to cycle even in the same person.

Cycles often shorten first, then lengthen and become unpredictable
Oestrogen fluctuates rather than following a smooth curve
Progesterone tends to decline as ovulation becomes less frequent
Common features: hot flushes, sleep disruption, mood changes, heavier or lighter bleeding

Tip: switch on "show LH & FSH" above to see how FSH trends higher and LH becomes less predictable in this pattern.

This tool is an educational simplification to help you understand general hormone patterns. It isn't a diagnostic tool and doesn't replace individual assessment. If you'd like help understanding your own cycle, book a consultation.

How a hormone imbalance shows up

The signs depend on which hormones are involved, but common ones I see in clinic include:

Periods that are irregular, heavier, lighter, or unpredictable
Mood swings, anxiety, or low mood that feel hormonally timed
Sleep that falls apart for no obvious reason
Stubborn weight changes, especially around the middle
Skin and hair changes, acne, or unwanted hair growth
Fatigue that doesn't lift with rest
Brain fog and difficulty concentrating

None of these symptoms on their own confirm a hormone imbalance. But when you start to see a cluster of them, especially tied to your cycle or a particular life stage, it's worth taking seriously rather than pushing through.

What to do about it

A hormone imbalance isn't something you fix with a single supplement or a quick swap at the chemist. It needs an actual understanding of which hormones are out of step and why, which is exactly what I walk through in this post on understanding your hormones instead of guessing.

If your symptoms are turning up in your late 30s or 40s, fatigue, brain fog, and weight that won't budge no matter what you do, it may be perimenopause specifically. I've written a full breakdown of what that looks like here: Is It Perimenopause? Why You're Exhausted, Foggy, and Gaining Weight Despite Doing Everything Right.

You don't have to figure this out alone

Hormone imbalances are common, but common doesn't mean you should just live with it. The first step is understanding your own pattern, not guessing at it.
