When Your Doctor Believes You: Finding Care For EDS, POTS, MCAS

I'm a licensed professional counselor who specializes in chronic illness, and I can't tell you how many times I've watched the relief wash over someone's face when they finally find a doctor who believes them. Not just someone who nods politely and orders another round of normal labs, but someone who genuinely gets it.

That's why I was so excited to sit down with Dr. Kara Pepper, a board-certified internist in Atlanta who specializes in eating disorders and complex medical conditions like MCAS, EDS, and POTS. She's spent the last few years building a practice where she can actually spend time with patients—an hour, not ten minutes—and dig into what's really going on.

The First Thing That Helps: Someone Believing You

Dr. Pepper told me something that made me want to stand up and cheer: "If I stopped there and did nothing else, I think that's probably hugely therapeutic for patients just to feel like someone's listening."

She's talking about real, genuine validation.

By the time most people get to her, they've seen dozens of doctors. They've been told their labs are normal, maybe that they should try yoga, or to go see a therapist (not because therapy could help them process medical trauma, but because the implication is that it's all in their head). They're frustrated, exhausted, and often questioning their own reality.

Dr. Pepper's approach starts every new patient relationship with a talk: “Most people who get to me have seen multiple doctors, are frustrated with our healthcare system—if not overtly traumatized—and they're looking for someone who can help them feel like they're in charge of their health.” 

And then she says the words so many people have been waiting to hear: "I believe you. This is real. I know you're not faking it."

Why Your Tests Keep Coming Back Normal

Dr. Pepper explained something that I think every person with chronic illness needs to hear: modern medicine is miraculous when you fit in the box. She says, “we can do organ transplants and genetic modifications and all kinds of amazing things.” But if you don't fit in that box —and most of her patients don't—it's really hard to get answers.

These particular diagnoses don't always have reliable testing. You can have batteries of labs, scopes, and scans, and they're all looking for structural diseases. Things you can see with your eyes or detect in the labs. But conditions like POTS, MCAS, and EDS are often functional problems, and we just don't have great tests to pick them up consistently.

That doesn't mean you're making it up. It means the tests aren't looking for what you actually have.

These are clinical diagnoses. That means a doctor who understands these conditions needs to listen to your story, put the pieces together, and validate what your body has been telling you all along.

The Eating Disorder Connection Nobody Talks About

One of the most interesting parts of my conversation with Dr. Pepper was about the overlap between eating disorders and this triad of conditions—EDS, POTS, and MCAS. And it might be what you think.

Dr. Pepper started her practice focusing on adults with eating disorders. But as she puts it, no one "just" has an eating disorder. The more she started digging with patients, the more these other invisible illnesses came to the surface.

Here's what that actually looks like: Someone comes in with what looks like a classic eating disorder. But when you really listen to their story, they tell you that as a kid, they just didn't feel good before or after they ate. Maybe vegetables made their mouth tingle. Maybe certain meats upset their stomach. Maybe leftovers always made them feel terrible.

So they stopped eating those foods. And they got labeled as a "picky eater." Or they started losing weight and got rewarded for it, and then restriction took on a life of its own. Or they kept throwing up after meals—not because they were trying to be thin, but because they genuinely didn't feel good—and someone diagnosed them with bulimia. It can be hard to distinguish, because even when their primary reason is physical discomfort, the words they say might be related to weight stigma messages that are so pervasive in our society. 

Dr. Pepper explained it this way: "Sometimes the eating disorder itself is the trauma that provokes the MCAS. Sometimes it's that people had medical-based food reactions (that they did or didn’t have the language for) that led to restrictive behaviors."

It's bidirectional. And it matters which came first because it changes how you approach treatment.

If the primary issue is anxiety with OCD that's showing up around food, Dr. Pepper explains, you need to treat the anxiety and OCD. But if someone has been having real physical reactions to food since childhood, you need to understand what those reactions are about. Otherwise, they're still going to have feelings about the food they're eating, no matter how much exposure therapy or trauma work they do.

What Actually Helps (And Why It's Not Just "Drink More Electrolytes")

If you’re somehow not yet convince she understands, here’s another quote from our episode: "Nothing is more infuriating to patients than when I'm like, you know what? You should try to drink some water with some electrolytes in it and also sleep more and be less stressed out."

She gets it. Most people have tried the basics by the time they show up. Her job is to offer a selection of things they might not have tried yet.

For people with POTS, one of the most profound interventions she's found is actually looking at blood vessels. She says, “if you have a connective tissue disorder like EDS, your joints and muscles are stretchy—so it makes sense that your blood vessels might be too. When the blood vessels in your legs are too stretchy, blood isn't getting back up to your heart efficiently. And no amount of salt, water, compression socks, or physical therapy is going to fix that if you literally have a mechanical problem.”

She sends people to vascular specialists who can actually look at their blood vessels with an ultrasound. Some people end up getting stented in their pelvis or having procedures to close up veins that aren't working well. And about 80% of people get better.

It's not magic. It's just understanding what's actually happening in someone's body and addressing the root cause instead of throwing generic advice at them.

The Medication Conversation Nobody Wants to Have (But We Did)

Dr. Pepper and I talked about something I see all the time in therapy: people who are terrified of medication but don't always know why.

Sometimes it's philosophical. There's a growing belief that if you can't fix something naturally, then you're not really fixing it. That if you need to take something to manage your condition, you've somehow failed.

Dr. Pepper's take? That's pretty black-and-white thinking. We wouldn't look at any other condition so rigidly. We need a diversity of approaches.

She also acknowledged something important: some people with MCAS do have genuine reactions to medications—sometimes to the active ingredient, sometimes to fillers or dyes. When that's the case, working with a doctor who understands compounding or microdosing can be really helpful.

But she was also clear that medication fear isn't always about physical reactions. Sometimes it's about past medical trauma, or messages we've internalized about what "counts" as real healing. And that's worth examining too.

Her approach is to start low and go slow. Compound medications when needed to remove reactive ingredients. Listen to what patients are experiencing. And recognize that for most people, medications are tools that can be used safely and effectively—especially when you're working with a provider who takes time to understand your full picture.

And most importantly, believe patients when they say they're sensitive to medicines, because in this population, it's typical.

Finding Doctors Who Get It

This is the question I get asked constantly: How do I find a provider who understands these conditions?

Dr. Pepper's answer: community.

Not just for emotional support, though that's important too. But for practical help. Facebook groups and organizations like the Ehlers-Danlos Society can tell you about providers they’ve had luck with in your area. The people in these communities have already vetted the pelvic floor physical therapists who understand hypermobility, the doctors who won't dismiss you, and the therapists who get it. In fact, about 20% of my referrals come from our local Ehlers-Danlos facebook group. 

Nobody wants to waste time and money going from doctor to doctor. Community helps you skip that painful trial and error.

And here's something else I loved: Dr. Pepper herself learns from her patients. Her first MCAS patient came in years ago saying, "I've done all this research, I've talked to people all over the country, this is what I think I have." And Dr. Pepper had never even heard of it. We don't learn about MCAS in med school—the research wasn't really out until 2010-2012, so there's a whole gap in knowledge for mid-career physicians.

Instead of dismissing the patient, she got curious. She learned. And now it's a huge part of her practice.

Why There's Reason for Hope

Dr. Pepper ended our conversation with something I want every person reading this to hear: "Don't give up. Medical knowledge is rapidly evolving. We used to leech people for a living—we thought that was a really great idea to get rid of bad humors. We decided that's not a great idea anymore."

She's seen huge advancements even just in the course of her career, especially in this disease subset. Things are moving forward. Technology is helping. There's a growing community of physicians who are publishing research, talking daily about how to better treat these conditions, and actually moving the science forward.

Yes, we're still in the early stages compared to more well-known diseases. But it's getting better.

Even on the days where it feels pretty hopeless, hang in there. Find your community. Keep advocating for yourself. And know that there are providers out there who will believe you, who will sit with you in the mess, and who will partner with you to find answers—even when those answers don't fit neatly in a box.
