Why hormone imbalance isn't a diagnosis and what to ask instead

You've probably used the phrase yourself. Maybe to your GP, maybe to a friend, maybe in the search bar at midnight when you were trying to explain why you've felt like a different version of yourself for the past year or two. That phrase is hormone imbalance.

It's emotionally resonant. It captures something real about how you feel. And it has built a multi-billion-pound supplement industry on the back of it.

Here's the problem: hormone imbalance is not a clinical diagnosis. It has no agreed definition, no standardised criteria, and no diagnostic code. It describes a downstream effect (something that happens as a result of something else) without ever identifying what that something else actually is.

That distinction matters more than any supplement you've been sold.

Your hormones are always downstream of something

This is the most important thing to understand about hormonal health.

Your hormones did not just decide to 'go wrong'. Something upstream is driving the disruption. Estrogen, progesterone, insulin, cortisol, and thyroid hormones are all in constant communication with one another and with the broader systems of your body (1). When that communication breaks down, there is almost always a reason.

Progesterone, one of the most common concerns I hear from people, is almost always suppressed downstream of something else, whether that's chronic stress, blood sugar instability, or poor estrogen clearance. Insulin, your blood sugar hormone, is not a sex hormone; it can be an important driver of many symptoms commonly labelled as hormone imbalance (2). Cortisol suppresses progesterone, disrupts your cycle, and drives inflammation (3).

Thyroid hormones regulate your metabolism in ways that mimic almost every symptom on the hormone imbalance checklist (4), and they can be missed by standard testing.

When your cycle is irregular, that is information. When your PMS is severe, that is information. When you are exhausted in a way that sleep doesn't fix, that is information. Your body is not broken. It is communicating that something in its environment needs addressing.

What could be driving your symptoms

If you've been told you have a hormone imbalance by a practitioner, a wellness account, or your own intuition, one or more of the following could be what's happening underneath it.

Chronic inflammation disrupts hormone signalling at the receptor level (5). This means that even when your hormones are being produced in the right amounts, inflammation can prevent them from being received and used properly. Inflammatory drivers include diet, gut permeability, environmental chemical exposure, poor sleep, and unmanaged stress. It is thought to be one of the more consistently underdiagnosed root causes and is present across a range of hormonal conditions (6).

Blood sugar dysregulation, specifically high insulin, directly raises testosterone, suppresses progesterone, and fuels the inflammation mentioned above (7). The 3 pm energy crash, the anxiety that ramps up before your period, the insomnia, the weight that sits around your middle and won't shift: blood sugar is often the unglamorous first chapter of the hormonal story.

Gut dysfunction affects how your body processes and eliminates estrogen. A community of gut bacteria called the estrobolome is responsible for metabolising used estrogen and helping the body excrete it. When the gut microbiome is disrupted through antibiotics, chronic stress, poor diet, or environmental toxins, excess estrogen gets recirculated back into the bloodstream rather than eliminated. This is a key mechanism behind estrogen dominance, heavy periods, and fibroid growth (8). Addressing hormones without addressing the gut is like trying to drain a bath with the tap still running.

HPA axis dysregulation is the clinical reality behind what is sometimes loosely called adrenal fatigue. Your hypothalamic-pituitary-adrenal axis is your stress response system, and under chronic activation, it prioritises cortisol production over sex hormone production. Chronic stress materially disrupts your cycle, mood, thyroid function, sleep, and progesterone levels through a specific, measurable physiological pathway (9).

Thyroid dysfunction can sometimes be missed during initial assessment. TSH alone, the standard test offered, can miss subclinical thyroid issues that are causing significant symptoms (10). An underactive thyroid can mimic almost every symptom associated with hormone imbalance: fatigue, weight gain, hair loss, low mood, heavy periods, brain fog, and difficulty regulating temperature (11). 

If you've experienced these symptoms and only had TSH tested, then you might not have been fully assessed.

Three questions worth taking to your next GP appointment

Rather than saying "I think I have a hormone imbalance," which might give a busy doctor something easy to dismiss, try these instead:

• Can we investigate what might be driving my symptoms at a root cause level, specifically inflammation markers, a full thyroid panel including T3 and T4, and insulin resistance?
• Has my estrogen metabolism been assessed, including how I'm processing and eliminating it?
• What do you think is driving this symptom specifically, and what would we need to rule out before reaching for hormonal contraception as a first-line response?

You are allowed to ask these questions. You are allowed to expect answers. And if you're not getting them, a second opinion is always a reasonable next step.

What working with a root cause practitioner looks like

So many women spend years being told their symptoms are normal, their concerns are overreactions, and their results are fine. They were not fine. The symptoms were real. The exhaustion of trying to self-research your own health because no one else is doing it for you is real.

Root-cause nutritional therapy starts from a different premise: that symptoms are information, and that information deserves proper investigation rather than a generic protocol and a supplement recommendation.

That sometimes means starting with thorough testing to understand what is actually happening in your body. Building a personalised nutrition, lifestyle, and supplement plan around your results. And working with you over time, rather than handing you a 30-day reset and wishing you luck.

If you've been struggling with hormonal symptoms and feel like you've been going around in circles, that's not a reflection of your body being broken. It's a reflection of the fact that you haven't yet been given the right framework for understanding what's driving things.
