Mast cells are meant to activate during a threat and then reset.

In mast cell activation syndrome, that reset does NOT happen.

The cells remain activated, leaking inflammatory mediators and driving both local and systemic symptoms.

This ongoing activation is a major driver of chronic inflammation that no one ever hears about.

If MCAS brought you here, does this sound familiar? 👇

Don’t be scared.

I know that it can feel impossible to hear when your symptoms are unpredictable or frightening, but here’s what I want to say clearly and without hesitation: the answers exist.

And so do clinicians who are willing to listen, learn, and walk this path with you.

Keep advocating. Keep learning. Keep trusting what your body is telling you.

This is a moment from my conversation with Natalie Jill Fit. We went deep.

Unexplained liver enzyme elevations or odd autoantibody results aren’t “random,” and they’re not always signs of primary liver disease.

For some patients, mast-cell dysfunction can drive liver inflammation or even influence antibody patterns... something many clinicians don’t routinely consider.

MCAS isn’t the answer to everything, but ruling it out can bring clarity when your labs don’t match your symptoms.

I see this ALL the time.

A patient comes to see me who is struggling with unexplained symptoms and has been diagnosed with conditions like ALS, autoimmune diseases, or chronic fatigue, but no one ever asks about their history of exposure.

Bartonella is a perfect example.

It’s not just “cat scratch fever.” It can be transmitted by ticks, fleas, lice, and even seemingly healthy animals. And it doesn’t always cause immediate symptoms…it can actually take years before neurological or inflammatory issues show up.

Yet, so many doctors AREN’T testing for it.

If you’ve been dealing with mystery symptoms, chronic illness, or a diagnosis that doesn’t quite add up, find someone who will dig deeper.

Your history matters. Exposures matter. And testing for infections like Bartonella could be the missing piece.

With the holidays coming up, many of us are cooking more than usual! If you have MCAS or histamine intolerance, even small choices in the kitchen can make a big difference in how you feel.

So let’s start with one of the simplest places to make a swap: your cooking oils.

Some are naturally lower in histamine and gentler on your body, while others can contribute to inflammation, oxidative stress, or symptom flares, especially when heated past their smoke point.

If this is something you’re navigating, comment LOWHIST below and I’ll send you my complete Low Histamine Diet Guide. I'll walk you through what to eat, what to avoid, and how to support stability through the holidays and beyond 🍽️

Can hormones calm your mast cells… or make them more reactive?

For patients with MCAS, the answer isn’t one-size-fits-all. Hormone replacement therapy can be incredibly helpful for some individuals, but only when it’s carefully tailored to maintain stability.

Estrogen and progesterone directly influence mast-cell behavior. Sudden shifts can provoke symptoms, while steady, physiologic hormone levels may actually support immune regulation and reduce reactivity.

With the FDA recently removing the black-box warning from most menopausal hormone therapies, many patients are revisiting whether HRT could be appropriate for them, especially if symptoms worsen with their cycle or during perimenopause.

If you suspect your hormones and mast cells are connected, seek out a clinician who deeply understands both. Personalized care makes all the difference.

If you’ve been feeling pressured by all the fasting trends, I want you to hear this ⬇️

Not feeling hungry isn’t “discipline.” Sometimes it’s dysfunction.

Stress hormones, thyroid issues, gut inflammation, chronic infections, MCAS… they can all silence appetite. And when you’re already dealing with a complex illness, skipping meals doesn’t strengthen your body, it strains it.

You need protein. You need nutrients. You need fuel to support healing.
And if you’re on GLP-1s like semaglutide or tirzepatide, this becomes even more critical.

Fasting has its place in longevity research, absolutely... but your context matters. Your biology matters.

When it comes to fasting trends, what feels confusing or unclear for you? 👇

My Story

I've always been driven to treat patients who are unable to get answers about their health from other doctors. I refer to the phenomena as “mystery-illness” patients. These patients have complex, chronic illnesses that no one else has been able to figure out. This has become my niche and I believe that is because I think outside the conventional box of medicine.

I know that these patients are sick and I know there's something wrong, and I desperately want to figure it out for them.

While I’ve always been passionate about helping patients get to the root cause of their illness, my practice and understanding of the human body has evolved through my personal experiences.

When I first started my integrative medicine practice nine years ago, I was introduced to Dr. Richard Horowitz, when we spoke at a conference together. I was overwhelmed in a good way by the information that he presented, and I vividly remember the conversation I had with him afterwards. He knew that I was practicing medicine in Westchester County, NY, a suburb of New York City, which is endemic for Lyme disease.
