Why You Feel “Off” Even When Your Labs Are Normal
“Everything looks normal.”
Have you ever heard those words after having lab work done—even though you know you don't feel like yourself?
I have.
Maybe you're exhausted even after a full night's sleep. You're gaining weight despite doing all the “right” things. Your mood has changed. Your brain feels foggy. Your hair is thinning. You're not sleeping well. Or you simply know that something is different.
And yet, you're told your labs are “normal.”
This is something I hear from patients often, especially women in their 40s, 50s, and beyond. It's also something I've experienced personally.
One of the reasons I started Luxe Longevity was because I believe we need to look at the whole person, not simply whether a laboratory result has an H or L next to it.
“Normal” Doesn't Always Tell the Whole Story
Laboratory reference ranges are important. They help clinicians identify abnormalities, diagnose disease, and guide medical care.
But a number falling within a reference range doesn't automatically explain how you feel.
Your symptoms matter, too.
At Luxe Longevity, I like to look at the bigger picture: your laboratory results, symptoms, health history, medications and supplements, lifestyle, risk factors, and how different biomarkers relate to one another.
Sometimes it's not one dramatically abnormal result that tells the story.
It's several pieces of the puzzle.
Why I Like Having a More Complete Thyroid Baseline
TSH is commonly used as the first-line screening test for thyroid dysfunction, and it provides valuable information.
But personally, I prefer to have a more complete thyroid picture as a baseline rather than waiting until someone's TSH becomes abnormal.
When appropriate, I look at TSH, free T4, free T3, thyroid peroxidase (TPO) antibodies, and thyroglobulin antibodies.
Why?
Because I want to know where you started.
If you're feeling great today, those results give us something to compare with if you come back several years from now saying:
“Something has changed. I'm exhausted. My hair is falling out. I'm gaining weight. I have brain fog. I just don't feel like myself.”
Thyroid autoimmunity is particularly important to be aware of in women. Hashimoto's thyroiditis is much more common in women than men, and thyroid antibodies may be detectable before overt hypothyroidism develops.
Having thyroid antibodies doesn't automatically mean someone needs medication, and comprehensive thyroid testing isn't universally recommended as routine screening for every person.
For me, however, knowing a patient's baseline provides another piece of their health history that may become valuable later.
This One Is Personal for Me
For years, I struggled with fatigue.
My TSH was checked and fell within the laboratory reference range. I kept being reassured that my thyroid was fine.
But I didn't feel fine.
Eventually, I asked for additional thyroid testing, including free T4 and free T3. My free T4 was within range, while my free T3 was lower than I expected in the context of the overall picture.
It prompted me to look more closely rather than ending the conversation because my TSH was “normal.”
That experience changed the way I think about laboratory testing.
I don't want to wait for a lab value to become dramatically abnormal before I start paying attention to what a patient has been telling me all along.
The Same Is True for Metabolic Health
Another biomarker I pay close attention to is fasting insulin.
Most people are familiar with fasting glucose and hemoglobin A1C. These are incredibly important tests—but they don't tell us exactly the same thing as insulin.
As the body becomes less responsive to insulin, the pancreas may compensate by producing more of it. For a period of time, that additional insulin can help maintain relatively normal blood glucose.
This is one reason I like looking at fasting insulin alongside glucose, A1C, triglycerides, HDL, blood pressure, waist circumference, family history, medications, and other metabolic risk factors when appropriate.
One insulin level doesn't diagnose someone's entire metabolic health. But I don't believe we should ignore a potentially useful piece of information simply because glucose and A1C haven't become abnormal.
I would much rather have a conversation about metabolic health before someone develops diabetes than after.
That's what longevity medicine means to me.
And Then Perimenopause Hit Me
Years later, I had another experience that reinforced how important it is to listen when your body is telling you something has changed.
I started feeling “off.”
My periods had become inconsistent, but they hadn't stopped completely—and they still haven't. I still get a period occasionally.
That's an important point because you don't have to stop having periods to experience symptoms related to perimenopause.
Perimenopause is the transition leading up to menopause, and it can begin years before your final menstrual period. While the length varies considerably from woman to woman, the transition can last 7–10 years or even longer for some women.
During that time, hormone levels can fluctuate significantly. Periods may become shorter, longer, heavier, lighter, closer together, farther apart—or occasionally disappear and then return.
And the symptoms can extend far beyond changes in your menstrual cycle.
For me, it wasn't just one thing.
I became much more irritable. The brain fog was crazy. I wasn't sleeping well. My knees hurt terribly. My hair was falling out. I started experiencing urinary incontinence.
Even my relationship was being affected. My husband was beginning to wonder if I still loved him because I simply didn't feel like myself.
So I did what I encourage my patients to do.
I paid attention and investigated.
I checked my labs and noticed changes, including an elevated cholesterol level—which was unusual for me.
After reviewing my symptoms, history, and laboratory results, I started estradiol and progesterone as part of my own perimenopause care.
The changes I experienced were incredible.
Within about a month, I was sleeping again. My brain fog improved. My knees stopped hurting. My urinary symptoms improved. I felt more like myself emotionally.
And yes—my husband felt loved again.
Even my hairstylist noticed a difference. She asked me what I was doing because my hair had become noticeably thicker again.
When I repeated my laboratory testing approximately one month after starting hormone therapy, my cholesterol had returned to my previous range as well.
That was my individual experience. I don't share it to suggest that every woman will experience the same results or that estradiol should be used as a treatment for high cholesterol.
I share it because it taught me something incredibly important:
Perimenopause doesn't begin when your periods stop. And when your body is telling you that something has changed, it's worth listening.
Estrogen Affects Much More Than Hot Flashes
When people think about menopause, they often think about hot flashes and night sweats.
But estrogen has effects throughout the body, which helps explain why the menopausal transition can involve such a wide variety of symptoms.
Changes during perimenopause and menopause may involve:
Sleep
Mood
Memory and concentration
Hair and skin
Bones
Muscles and joints
Sexual health
Vaginal and urinary health
Body composition
Metabolic and cardiovascular health
Menopause is also associated with changes in cardiovascular risk factors, including lipid profiles. Menopausal hormone therapy can influence cholesterol levels, although those effects vary depending on the individual, formulation, dose, and route of administration.
Hormone therapy shouldn't be prescribed simply as a cholesterol-lowering treatment or solely to prevent cardiovascular disease.
The decision to use hormone therapy should be individualized based on symptoms, age, health history, timing relative to menopause, risks, goals, and personal preferences.
This isn't about giving every woman hormones. It's about having the conversation.
Sometimes Your Symptoms Overlap
This is another reason I don't like looking at one laboratory value in isolation.
Think about some of the common symptoms women experience in midlife:
Fatigue. Brain fog. Hair changes. Weight changes. Poor sleep. Mood changes.
Are those caused by perimenopause?
Thyroid dysfunction?
Changes in metabolic health?
Iron deficiency?
A vitamin deficiency?
Poor sleep?
Chronic stress?
Medication?
Or a combination of several things?
You can't answer those questions by looking at one number. That's why the patient's story matters just as much as the laboratory report.
Nutrient Levels Matter, Too
Fatigue isn't always hormonal.
Depending on someone's symptoms and medical history, I may also consider biomarkers such as vitamin B12, vitamin D, folate, ferritin, and iron studies.
But more isn't always better.
Supplements can be extremely helpful when they're actually needed, but taking large amounts simply to push a laboratory value higher isn't necessarily beneficial—and in some cases can be harmful.
That's why I prefer an individualized approach rather than blindly adding supplements.
Cholesterol Is More Than One Number
A standard lipid panel provides valuable information, but cardiovascular risk is more complicated than simply looking at total cholesterol.
Depending on someone's history and risk factors, additional biomarkers such as ApoB, lipoprotein(a), high-sensitivity CRP, glucose regulation, and other metabolic markers can provide additional context.
Blood pressure, smoking history, family history, age, activity, body composition, and other factors matter, too.
The purpose isn't to create fear around numbers.
It's to better understand your individual risk factors so you can make informed decisions about your health.
The Goal Isn't to Chase “Perfect” Numbers
This is an important distinction.
There are many “optimal laboratory ranges” circulating online, particularly in the hormone, wellness, and longevity spaces. Not every proposed optimal range is supported by strong scientific evidence, and a higher or lower number isn't automatically better.
At Luxe Longevity, the goal isn't to chase numbers.
The goal is to understand you.
What are your symptoms?
How have they changed?
What does your health history tell us?
What do your labs show when we look at them together?
Are there trends we should be watching?
And are there safe, evidence-informed changes that could help you feel better while supporting your health for the years ahead?
This Is Why I Started Luxe Longevity
After more than 18 years working in critical care, I have tremendous respect for traditional medicine. I've seen firsthand what modern medicine can do when someone is critically ill.
But my own experiences also made me passionate about what happens before someone becomes sick.
I want people to understand their bodies.
I want women to know that feeling dramatically different in midlife isn't something they simply have to accept.
I want patients to understand their metabolic health before they're told they have diabetes.
And I want people to feel comfortable asking questions when something doesn't feel right—even when their initial testing looks “normal.”
Sometimes the answer isn't another medication or hormone. Sometimes it's nutrition, sleep, strength training, stress management, correcting a deficiency, addressing another medical condition, or simply monitoring something over time.
But finding the right answer starts with listening.
You know your body. If something has changed, it's worth asking why.
