Normal Bloodwork, Low Energy, and Early Perimenopause

If your bloodwork came back normal but you still do not feel well, you are not imagining it, and you are not alone. This is one of the most common conversations I have with women in perimenopause. Below is what is actually happening during this stage, why standard testing often misses it, and what can be done about it.

Perimenopause starts earlier than most women expect

Perimenopause can begin as early as your late thirties or early forties, and it rarely announces itself.

Hormonal changes can begin before you notice the symptoms we typically associate with perimenopause. You don’t necessarily need to have irregular periods or hot flashes for your hormones to be changing. Those more noticeable symptoms often become more apparent as perimenopause progresses, but the early changes can be much more subtle.

You might simply notice that you don’t feel quite like yourself. Your energy, sleep, mood, appetite, or stress tolerance may start to shift in ways that are easy to brush off or attribute to everything else going on in life.

It's also important to note that menopause itself is technically a single day: the day you have gone twelve full months without a period. Everything leading up to that point is considered perimenopause, and the day after marks the beginning of postmenopause.

The early symptoms are more subtle than you think

The first shifts can be subtle. Maybe your sleep starts to change, your energy isn’t quite what it used to be, your mood feels different, or you start noticing changes in where you carry weight, particularly around your middle.

Because these changes can be gradual and are often attributed to stress, getting older, a busy schedule, or simply “life,” many women are well into perimenopause before anyone connects the dots.

One of the patterns I hear most often is that the things that used to work just don’t seem to work the same way anymore. Maybe an extra coffee or energy drink used to get you through a long day, and now it barely touches the fatigue. Maybe your usual approach to food and exercise used to keep your weight stable, and suddenly your body seems to be responding differently, even though your routine hasn’t meaningfully changed.

These changes can be easy to dismiss when they happen one at a time. But sometimes, they are the first signs that something has shifted.

Why "your hormones look fine" should not be the end of the conversation

Testing can add to the confusion. There is no single hormone test or level that confirms perimenopause, so it can't be diagnosed from hormone bloodwork alone.

This matters because being told your hormones are “fine” shouldn't mean nothing can be done. Hormone levels can fluctuate significantly throughout perimenopause, and the changes may not always show up clearly on a single blood test. Treatment decisions can also be based on symptoms, health history, and quality of life, not just what appears on a lab report.

Later in perimenopause, depending on someone’s symptoms, health history, and quality of life, that conversation may include hormone replacement therapy. I hold a prescribing licence, and I continue to pursue education and training in hormone replacement therapy so that I can help educate my patients, discuss the potential benefits and risks, and work with them to determine what options may be appropriate and safe for them.

The goal is not to assume that everyone needs hormone therapy. It is to make sure you understand your options and can make an informed decision about what is right for you.

Normal bloodwork means you are not in a state of disease

I want to say this as plainly as I can, because so many women arrive at their appointments having felt dismissed by “normal” results. Bloodwork coming back within the expected range can tell us that there may not be an obvious disease process showing up on those particular tests. It does not mean what you are feeling is imagined, and it does not mean there is nothing we can do to better understand or support it.

I also want to note that most of the women I work with are not "unhealthy". They have tried the diets, the exercise, the protocols they found online, and they are still not seeing the changes in energy, metabolism, or how they feel that they were hoping for.

Usually, what is missing is not effort. It is a set of smaller, more specific adjustments that most of us were never taught, along with someone who can help identify which ones actually apply to you.

Optimal vs. normal labs

Part of my work is looking at bloodwork strategically. That means considering not only whether your numbers fall within the expected reference range, but also whether they are optimal, how they relate to one another and what the overall picture may suggest.

Sometimes, the most useful test is one that was never ordered in the first place.

Naturopathic doctors can also requisition bloodwork, so if you feel like something is missing from the picture, it can be worth having a conversation about what testing may or may not be appropriate for you.

Why having support makes a difference

Trying to figure all of this out on your own can be difficult, particularly in a world filled with endless and often contradictory health information.

And I say that as a naturopathic doctor who relies on my own team of practitioners to stay well. I don’t expect myself to know everything or figure everything out on my own, and I don’t think you should have to either.
