My Labs Are Normal…So Why Do I Still Feel So Bad?
Have you ever been told:
"Good news! Your labs are normal."
But you still feel exhausted.
You can't lose weight no matter how hard you try.
Your hair is thinning.
You have brain fog.
You're cold all the time.
You just don't feel like yourself.
If so, you're not alone.
This is one of the most common conversations I have with new patients. In fact, most of the lab work I review is technically "normal." The question I ask is a little different:
Are these results optimal for this patient?
There Are Three Common Reasons This Happens
1. "Normal" Doesn't Always Mean "Optimal"
One of the biggest misconceptions about lab work is that a normal result automatically means you're functioning at your best.
In reality, most laboratory reference ranges are designed to help identify disease. They are an important tool, but they don't always tell us whether your body is functioning optimally.
Here are a few examples of the difference between “normal” ranges and the optimal targets I commonly use in my practice.
Lab Typical Lab Reference Range My Optimal Target
TSH 0.4–4.5 mIU/L 1–2 mIU/L
Fasting Glucose 70–99 mg/dL 70–85 mg/dL
Fasting Insulin Up to 25 µIU/mL 2–6 µIU/mL
Vitamin D (25-OH) 30–100 ng/mL 60–80 ng/mL
hs-CRP Less than 3.0 mg/L Less than 1.0 mg/L
Reference ranges vary by laboratory.
Does this mean everyone outside these targets needs treatment?
Absolutely not.
These are simply the ranges I often aim for when evaluating patients as a whole. Your symptoms, medical history, medications, age, and overall health are just as important as the numbers themselves.
2. Often the Right Labs Were Never Ordered
Another thing I see every week is that patients have been told their labs are normal—but only a basic panel was performed.
Depending on your symptoms, there are often additional tests needed.
For example, I frequently meet patients struggling with fatigue or weight loss resistance who have never had a fasting insulin level checked.
Sometimes the missing piece isn't an abnormal result.
It's a test that was never ordered.
3. Labs Are Only One Piece of the Puzzle
I don't treat lab numbers.
I treat people.
Lab work is incredibly valuable, but it should never be interpreted without considering the whole person.
Your symptoms matter.
Your health history matters.
Your lifestyle matters.
Your medications matter.
Your lab trends over time matter.
When all of those pieces are considered together, they often tell a much clearer story than any single number ever could.
The Bottom Line
If you've been told your labs are normal but you still don't feel like yourself, don't assume it's "just getting older" or that you have to learn to live with it.
Sometimes your lab results really are reassuring.
Sometimes the answer is hidden in a pattern of results that are technically normal but not ideal for your individual situation.
And sometimes the most important clue is a test that hasn't been ordered yet.
You deserve to have your symptoms taken seriously and evaluated in the context of your whole health—not just whether a number falls inside a reference range.
