Start where your symptoms are

Most people find us with a symptom nobody has connected to anything yet, and a folder of results that all came back normal. So this library is organized by problem rather than by date. Pick the door that sounds like your situation and you'll find where to start, what to read next, and everything else we've written about it.

Long COVID

Long COVID Isn’t One Disease. It’s Several Overlapping Problems.

Two people catch the same virus and end up with completely different illnesses. That’s the clue most of medicine misses about long COVID: it was never one disease. It’s more like a recipe.

Why Are Long COVID Clinics Closing (and What Happens to Patients Now)?

The funding dried up. The research centers folded. But the patients are still in my exam room. Long COVID clinics are closing across the country with zero approved therapies to show for a billion-dollar initiative… and 17 to 23 million Americans who are still sick. Dr. Aaron Hartman on why this pattern is older than the pandemic, and what it tells us about how medicine handles the patients it can’t explain.

The Peptide Paradox: How Restricting Safe Clinical Access Made the Wild West Bigger

The FDA restricted 19 peptides in September 2023. One month later, tirzepatide was approved for weight loss. Dr. Hartman explains what actually happened.

When the Body Forgets How to Heal

Your body doesn’t forget how to heal all at once. It happens slowly: growth hormone pulses less, sleep gets shallower, injuries take longer, connective tissue stops holding.

Your Body Has Been Making Peptides Since Before You Were Born

Everyone’s heard about peptides. Almost nobody has a clear answer to the most basic question: what are they? Here’s the explanation you’ve been waiting for.

The Pentad Supersyndrome: Five Conditions. One Root Cause.

If you’ve been told nothing is wrong but you can’t get off the couch — or you have a folder full of specialist notes and no unifying diagnosis — this framework may finally explain why.

Perimenopause Is a Litmus Test.

What if perimenopause symptoms aren’t just about hormones? Dr. Hartman and Cynthia Thurlow on gut health, the estrobolome, and midlife resilience.

Becoming a Medical Feminist

About 80% of the patients Dr. Hartman sees are women. And over the years, he noticed a pattern. This article names six specific ways the system fails them (and why it’s not random).

Medical Blind Spots • Pt 2

Medical Gaslighting

If you’ve ever been told your symptoms are stress, anxiety, or “just in your head,” you’ve experienced what Dr. Hartman calls medical gaslighting. It’s not manipulation. It’s a structural problem in how medicine handles uncertainty. And it has a pattern.

How Often Is Modern Medicine Wrong?

Some medical errors are just errors. Others become doctrine.

How Much Sun Exposure Do You Need for Vitamin D?

The sun has been vilified for decades, but emerging research shows that avoiding it altogether may be just as dangerous as overdoing it. Dr. Hartman breaks down exactly how much sun you need and how his family navigates this balance every summer.
