Lindgren Functional Medicine

Lindgren Functional Medicine Treating the root cause of health conditions helping our patients enjoy good health! My journey to this place was anything but linear.

It took years of working in the conventional medical system before it became clear to me that what I was practicing as a physician wasn't a solution for wellness, it was a practice of fixing numbers with pharmaceuticals. This problem needed this drug. That problem needed that drug. No physician will tell you that they dedicated their entire professional career to become a drug dealer, but that is what I felt I had become. For the vast majority of patients, bandaging the same illness with the same medication doesn't fix the problem. What patients need today - what we as people need today - is a guide to wellness. I will tell you that wellness isn't about having perfect numbers or taking all the right pharmaceuticals. Wellness is a way of life - a way of life that focuses on nutrition, hormone optimization, stress reduction, immune system support, detoxification, and neurotransmitter balance. I am confident in telling you that wellness is absolutely attainable. Together, I would love to guide you along the path that will take you from where you are now, to the place where you can be the best you can possibly be. Fellowship trained in functional medicine and certified by both the American Academy of Anti-Aging, Restorative, and Functional Medicine and the American Board of Family Medicine, I offer a holistic approach to my patients by focusing on optimization of each organ system. I specialize in treating female and male hormone imbalances, thyroid disorders, adrenal dysfunction, fatigue and pain syndromes, autoimmunity, and weight loss. I believe we can prevent and reverse many of the leading causes of chronic disease if we treat patients as one integrated system with scientifically-proven dietary changes, natural supplementation, and restoration of healthy hormone balance. Functional medicine is individualized health care. If our goal is wellness, the one size fits all paradigm simply does not work. Patients deserve customization of their heath care. This is my focus and my passion.

Fatigue that won’t budge.
Brain fog that makes you question yourself.
Weight changes, cold sensitivity, mood shifts.

These aren’t random, and they’re not “just getting older.”

Your thyroid plays a major role in how your entire body functions. When it’s off, everything feels off.

At Lindgren Functional Medicine, we look beyond surface-level labs and symptom suppression. We take a root-cause approach to thyroid disorders because real balance comes from understanding the whole picture, not just one number on a chart.

"Something Shifted: The Mandela Effect and Why So Many People Feel 'Off'"

Have you ever been absolutely certain of something…
only to be told it never existed?

Not that you remembered it wrong.
That it was never there at all.

That moment doesn’t just mess with your memory.
It messes with your sense of safety.

In this episode of The Dysfunction Files, we dive into the Mandela Effect - not as an internet curiosity, but as a nervous system phenomenon.

Because when reality stops feeling predictable, the body reacts.

And maybe that’s why so many people have been saying the same thing lately:

“I don’t feel like myself anymore.”

"Maybe Reality Wasn’t Broken After All"

We don’t actually know why millions of people remember the same things differently.
We don’t know if it’s memory.
Or timelines.
Or perception.

But maybe that’s not the point.

Because the body doesn’t need certainty.
It needs coherence.
It needs to feel grounded.

Maybe reality never shattered at all…
Maybe it just asked us to notice where we’re standing.

"When Reality Quietly Shifts"

Sometimes reality doesn’t break.
It doesn’t shatter.
It doesn’t announce itself.

It just… shifts.

A logo changes.
A movie line disappears.
A memory doesn’t match the record.

And suddenly you’re not questioning the thing -
you’re questioning yourself.

"Why the Mandela Effect Feels So Unsettling"

The Mandela Effect doesn’t feel disturbing because you’re “wrong.”

It feels disturbing because your body experienced something…
and then reality told you it didn’t happen.

That disconnect doesn’t hit logic first.
It hits the nervous system.

And that reaction?
It’s not crazy.

It’s biological.

Hot flashes. Brain fog. Mood shifts. Sleep issues.
For years, women were told these symptoms were “just part of aging” or worse, something to quietly endure.

Here’s the truth:
Menopause is a biological transition, not a breakdown.

Hormones don’t suddenly become dangerous.
Your body doesn’t stop deserving support.
And feeling miserable is not a requirement.

When hormones are evaluated thoughtfully and addressed appropriately, many women experience real relief clarity, energy, better sleep, and a sense of themselves again.

✨ You’re not imagining it.
✨ You’re not weak.
✨ And you’re not out of options.

Menopause deserves better conversations and better care.

"Do You Remember the Cornucopia… or Is That the Problem?"

Be honest -
do you remember the Fruit of the Loom cornucopia?

Because millions of people do.
And according to the company… it never existed.

That moment - when something you know you experienced is suddenly “wrong” - doesn’t just mess with your memory.

It messes with your nervous system.

This is why the Mandela Effect feels so unsettling…
and why your body reacts before your mind does.

Tell me you remember it too.

"Oxygen: The Therapy Medicine Forgot"

Did you know hospitals used to be built around oxygen?

Not supplements.
Not pharmaceuticals.
Oxygen.

And then - it vanished.

Not because it failed.
Not because it was dangerous.
But because you can’t patent air.

In this week’s episode, we open a medical file that never should have been closed - the real history of hyperbaric oxygen therapy, why it became “controversial,” and why it’s helping patients with long COVID, neurologic disease, chronic inflammation, radiation injury, and cancer recovery today.

If you’ve ever been told your labs are “normal” while your body says otherwise this episode is for you.

🎧 Episode 42 of The Dysfunction Files is live now.

"No - Oxygen Does Not Feed Cancer."

This myth refuses to die.

“Oxygen feeds cancer.”

It sounds logical - but biology doesn’t work that way.

Cancer actually thrives in low-oxygen environments.
Hypoxia makes tumors more aggressive, more inflammatory, and more resistant to treatment.

Radiation therapy, for example, requires oxygen to work properly.

Hyperbaric oxygen therapy corrects hypoxia, supports tissue recovery, immune function, and treatment response.

It’s not about replacing our other oncology tools.
It’s about removing cancer’s home-field advantage.

This week on The Dysfunction Files, we’re breaking down one of the most misunderstood conversations in cancer care - and why oxygen belongs in it.

🎧 Full episode drops tomorrow.

Before adding more supplements, workouts, or strict routines ....PAUSE.

One of the most helpful things you can do for your health in the new year is to get curious about your body:
• Notice patterns in energy, sleep, mood, and digestion
• Pay attention to symptoms you’ve been brushing off
• Ask why, not just how to push through

At Lindgren Functional Medicine, we believe better health starts with understanding not overwhelm.

Better health doesn’t come from doing more.
It comes from understanding more.
