Normal labs but still tired: what your body may be telling you
A reference range is a wide average. You are a specific person. Here is one signal worth tracking.

"Everything looks normal" and you still feel awful
Some of the most frustrating appointments I hear about are the ones where nothing is wrong on paper. You slept eight hours and woke up flattened. Your waistband is tighter and nothing about your eating changed. You feel anxious in a way that isn't you. Then the labs come back, someone says the word normal, and you leave with the same body you walked in with.
I recorded an episode with Cassie Milligan, a family nurse practitioner, and one line has stayed with me: labs can be wrong, symptoms usually aren't. That isn't a reason to distrust testing. It's a reminder that a reference range is a wide average, and you are a specific person. If you have been told you're fine and you still don't feel like yourself, this issue is for you.

Normal is a range. Optimal is where your symptoms ease.
Cassie put it simply: normal's not optimal. Standard reference ranges were largely built from research on white males, and ranges can differ by ethnicity, so a value that technically sits in range may still be far from where a particular woman feels well. She gave an example: two people can both have a ferritin of 60, and one feels exhausted and foggy while the other feels fine.
That's why she pairs numbers with what a person is actually living. The number that matters is the one where your symptoms ease. It also means your description of your own days is data, not complaining. Fatigue, broken sleep, brain fog, and feeling unlike yourself are information your body is offering, and they're worth investigating rather than dismissing.
What your body may be communicating
Perimenopause is the stretch of time when your body is preparing for menopause, and Cassie notes it can begin as early as 35 and last years. Here are some changes you may notice—and what they could mean.
EXPECTED CHANGE
Cycles that stop following a pattern
During perimenopause, hormones begin declining and fluctuating. I described it on the episode like small thruster jets on a rocket: sometimes both engines fire, sometimes one misfires. That's why one month can bring a very heavy period, the next month nothing, and the month after only light spotting. Those surges are part of the process, not proof you're imagining things.
WORTH A CONVERSATION
Fatigue that a full night of sleep doesn't touch
Sleep trouble and fatigue are the two symptoms Cassie hears most, along with abdominal weight gain without changed habits, night sweats and hot flashes, brain fog, joint aches, and bloating. Many women assume the tiredness is simply poor sleep, but she cautions there is often more underneath. Whether your evaluation has looked beyond a basic panel, including full thyroid, adrenal function, and ferritin rather than serum iron alone, is worth discussing.
REMEMBER
Common is not the same as something you must live with
Feeling unlike yourself is common in this transition. That doesn't mean it's the ceiling. Stress counts as a physiological input, not a personality flaw, and if pelvic symptoms are part of your experience too, an evaluation can help you understand what's happening and what your options may be.
TRY THIS ONCE A DAY THIS WEEK
The three-line symptom note
Before your next appointment, build the record that a single lab value can't hold. This is observation and language only.
- 1Write one line about sleep: how long it took to fall asleep, whether you woke, and whether you woke warm.
- 2Write one line about energy and mood: rate each from 1 to 10, and note anything that felt unlike you.
- 3Write one line about your cycle or body: bleeding, spotting, bloating, aches, or nothing to report.
At the end of the week, read the seven days together and underline the pattern you'd want a clinician to hear first. Bring the page with you.
Why You Don’t Feel Like Yourself with Cassie Milligan
Bree Allred with Cassie Milligan
Three things from my conversation with Cassie Milligan that changed how I listen to "I'm just tired."
- Symptoms carry information Labs can be wrong, symptoms usually aren't. If your numbers are in range and you still feel unwell, it's fair to ask what optimal looks like for you specifically.
- Hormones don't work alone Cassie's whole-body view includes gut, liver, adrenals, thyroid, and iron storage. She calls the thyroid the captain of the ship, since thyroid receptors sit on essentially every organ.
- Cortisol has a rhythm Cortisol should peak in the morning and taper by evening. Under sustained stress, Cassie says that rhythm can flip, leaving it elevated at night when you're trying to sleep.
What have you stopped mentioning because you assumed it was just your age?
Most women I meet have quietly edited their symptom list down to what feels acceptable to say out loud. This week, add one thing back. You know your body, and you deserve answers that match what you're actually experiencing.

If your symptoms are affecting your comfort, sleep, or confidence, you don't have to sort out which system is involved before you ask for help. Bring your notes and we'll look at it together.
