Guilty Habits Of A Functional Medicine Doctor
Looking at restaurant menus and calculating the protein.

Asking someone what their stool looks like before asking how their day is going.

Mentally diagnosing everyone at the grocery store.

Reading supplement labels for fun.

Having a cabinet full of supplements you “might need someday.”

Eye rolling, “Everything on my labs was normal.”

Struggling to explain to TSA that I'm not a drug dealer by the way I packed.

Things I will judge you for (a little) 😆

Taking a supplement once and deciding “it doesn’t work.”

Saying you’re gluten-free… except on weekends.

Sleeping 5 hours a night and asking which supplement will fix your fatigue.

Saying you “don’t have time to eat” but have time to scroll for 30 minutes.

Eating no vegetables all day, then taking a greens powder and calling it even.

Calling one bowel movement every 3 days “regular.”

Combining three different TikTok protocols and wondering why you feel terrible.

Unpopular opinion on functional medicine:

Some people are being over-tested.

I’m a big believer in testing. I use specialty testing all the time. But I also think functional medicine can get carried away with the idea that more data automatically means better care. It doesn’t.

If I order a test, I want to know what I’m going to do with the information. If the result isn’t going to change the plan, why am I ordering it?

I’ve seen people come in with thousands of dollars worth of labs, pages and pages of abnormal findings, and somehow they’re more confused than they were before they started.

That’s not the goal. Sometimes you need deeper testing. Sometimes you need basic bloodwork. Sometimes the patient’s history already tells you where to start.

Good functional medicine isn’t about finding as many abnormalities as possible. It’s about figuring out which ones actually matter.

Case Study: Brain Fog, Fatigue, Dizziness + Mold/Toxin Stress

A patient came in struggling with severe brain fog, daily fatigue, dizziness/lightheadedness, feeling generally unwell, and acne that worsened around her cycle.

History showed multiple mold exposures, and her testing helped connect the dots: mold-related toxins, poor detox capacity, blood sugar instability, nutrient depletion, low nutrient support, and a depleted hormone/stress-response pattern.

In Phase 1, we focused on the foundations:
- Removing food sensitivities, especially gluten
- Lowering mold exposure through food and environment
- Prioritizing protein at each meal
- Supporting hydration and electrolytes
- Repleting key nutrients
- Supporting detox capacity
- Improving sleep rhythm, walking, and gentle sweating

At her first check-in, her total symptom burden score dropped from 159 to 62.
Some of her biggest wins:
- Brain fog: 75%+ improved
- General fatigue: resolved
- Fatigue after eating: resolved
- Dizziness: resolved
- Cravings for sweets: resolved
- Waking unrefreshed: 75%+ improved
- Lack of energy: 75%+ improved
- Acne: starting to improve

This is a great reminder that symptoms like brain fog and fatigue are the result of multiple systems being overloaded at once: gut, detox, blood sugar, hormones, nutrients, and environment.

The goal is to find the pattern and support the body in the right order.

Cortisol gets blamed for EVERYTHING lately.

Weight gain.
Poor sleep.
Anxiety.
Cravings.

You actually NEED cortisol.

Cortisol should naturally be higher in the morning to help you wake up, get moving, think clearly, and have energy for the day.

Then it should gradually decrease as the day goes on so your body can relax and prepare for sleep.

The problem happens when that normal rhythm gets disrupted or overall production becomes too high or too low.

Underproducing people feel exhausted, unmotivated, foggy, and dependent on caffeine just to function.

And some people have a completely backwards pattern where they drag all day and suddenly feel wide awake at night.

That is why simply saying “you have high cortisol” or “you need to lower your cortisol” is often way too simplistic.

The goal isn’t LOW cortisol.

The goal is the RIGHT amount of cortisol at the RIGHT time of day.

This is why cortisol must be tested at 4 times throughout the day with a saliva test.

YES, WE WORK WITH KIDS.

When school starts, many parents notice their child struggling with stomach aches, headaches, fatigue, constipation, mood changes, frequent illness, or difficulty focusing.

Sometimes these symptoms get blamed on busy schedules, picky eating, anxiety, or “just being a kid.”

When symptoms are frequent, there may be underlying factors worth investigating including digestion, nutrient status, blood-sugar regulation, inflammation, food reactions, sleep quality, and more.

Our goal is to help parents better understand what may be contributing to their child’s symptoms and create an age-appropriate plan to support them.
