Hormone Health Is About More Than Hormones

When women come to me with questions about their hormones, perimenopause, or menopause, they often expect hormone testing to provide the answer. Sometimes it can be helpful. And sometimes they’ve already had their hormones tested, been told that everything looks “normal,” and are left feeling like there isn’t much else to look at or do.

The reality is that hormone levels are only one piece of the story. There are a number of other tests that may be worth considering depending on someone’s symptoms, health history, and individual circumstances. Many of these look beyond hormone levels themselves and can give us more information about what else may be contributing to how someone is feeling.

Hormone testing is useful, but it is not the whole answer

I always like to start with one important point: hormone testing can be useful, but it is not the whole picture.

Hormone levels naturally fluctuate. They can change from one day to the next, throughout the menstrual cycle, and from one month to another. This can make a single blood test difficult to interpret, particularly during perimenopause when hormone levels can be especially variable.

There also isn't one specific estrogen, progesterone, or testosterone number that tells us exactly what someone should do or how they should feel. These tests can give us useful information in the right context, but they are only one piece of the puzzle.

This is also why hormone testing isn't always necessary or routinely used when assessing perimenopause or menopause. Depending on the person and the situation, symptoms, health history, and other clinical information may tell us much more than a single hormone panel can.

The blood sugar test that usually gets skipped

One area that can easily get overlooked is a deeper look at blood sugar and especially insulin.

Fasting glucose and HbA1c are commonly tested, and they can give us useful information. But both can remain within a typical range for quite some time because insulin is working behind the scenes to keep blood sugar in check. Looking at glucose alone doesn't necessarily tell us how much insulin the body needs to do that job.

This is why I also like to consider fasting insulin, and in some cases, a two-hour insulin and glucose challenge test. With this test, we measure fasting glucose and insulin, you drink a standardized glucose solution, and then we measure both again at 30 minutes, one hour, and two hours. This gives us a more detailed picture of how glucose and insulin respond when consuming food, rather than only looking at fasting levels.

Why does this matter? Changes in insulin regulation can be relevant to many of the things women may be noticing during midlife, including changes in energy, weight, appetite, mood, and metabolic health. It is one of those areas where looking a little deeper can sometimes tell us more than the standard blood sugar markers alone.

Thyroid, including antibodies

Even when someone is at an age where perimenopause would be expected, I don't want to assume that reproductive hormones explain everything.

Thyroid health is another piece I think is important to consider. Rather than looking at TSH alone, a more complete thyroid assessment may include other thyroid markers and, when appropriate, thyroid antibodies. Autoimmune thyroid conditions can develop before more obvious changes show up on standard thyroid testing, so looking at the bigger picture can sometimes give us more context when symptoms don't quite add up.

Iron, and why ferritin alone can be misleading

When I say I want to look at iron, I mean more than just ferritin.

Ferritin is one of the most commonly ordered iron markers, and it can be very useful. But it can also rise in response to inflammation, which means a “normal” ferritin doesn't always tell us the full story of someone's iron status.

Looking at a broader iron panel, including markers like serum iron, TIBC, and transferrin saturation, can give us more context than ferritin alone. It helps us understand the bigger picture rather than relying on a single number.

Other tests to consider

I also consider things like B12, vitamin D, cholesterol, liver and kidney function, and inflammatory markers when they are relevant.

The goal isn't to test everything just for the sake of testing. It's to look at the bigger picture and make sure we're not overlooking something important.

Every test has to earn its place

The standard I hold is simple: Each test should have the potential to change what we do next. It might identify something worth addressing, or help rule something out so we have a better sense of what is and isn't contributing to someone's symptoms.

If a result isn't going to change the plan or add meaningful information, I don't see much value in ordering it just for the sake of having more data.
