Hi, I’m Jenny Paul Rothschild

Functional Health Practitioner | Microbiome & Mold Recovery Specialist

I help people uncover, understand, and address the root causes of their symptoms through functional lab testing and individualized nutrition & lifestyle education so they can build lasting health and immune resilience. 

Eight months postpartum and after a major gut and immune system crash - with inflammation readings at 3 times the upper limit, a positive autoimmune titer, and visits to 18 top well-meaning specialists with no real answers - I found functional health, nutrition, and research-based recovery.

Little by little, I managed to fully recover and became healthier than I was before. I made it my mission to learn everything I could to help others do the same.

MY HEALTH JOURNEY

I have always been “sensitive.”

I was that outwardly super sensitive, empathetic kid who felt too much, got sick all the time, and was always told something was off.

Then I became that inwardly super sensitive, overly functional Type A adult who still felt too much, got sick all the time, and always knew something was off.

When I turned 28, I started sleeping for 14 hours a day and not feeling rested.

In a panic to get my life back, I took some advice from a cousin to cut gluten. I thought, why in the world would gluten have anything to do with chronic fatigue, but I was desperate. And lo and behold, like magic, it worked! I knew deep down that it wasn’t the entire answer, but it’s all I knew to do, and no one had any better answers for me, despite my curiosity.

A few years later, I got married and then pregnant.

After a traumatic miscarriage, my digestive health started to tank.

It was never all that good, but this was different. The GI doc thought it was probably IBS, constipation and reflux, and of course, stress, but they couldn’t really do anything for me because I was already pregnant again. 

This pregnancy was healthy, thank goodness! And, I did relatively well through it despite the issues, and not being able to eat much more than my multivitamin for most of the first trimester (I lost 17 pounds). Constipation, reflux, and excessive nausea are normal in pregnancy, right?

4 months after the birth of our beautiful baby girl, the GI issues took an uptick with a vengeance.

IBS, constipation, reflux, so many new sensitivities I couldn’t keep count, tanking thyroid, energy, and mood, joint stiffness and pain, vision loss in my right eye, dryness in my eyes, mouth, and skin beyond any reasonable quotient, eye floaters, tinnitus, cervical dizziness, BPPV (vertigo), rapid weight and bone loss, 6 new cavities in the span of 3 months, teeth becoming translucent, newly discovered and rapidly worsening scoliosis and posture issues, numbness and circulation issues in my fingers and toes, temperature regulation issues, chemical sensitivities, the list goes on and on…

By 8 months postpartum, I had seen 18 of the best doctors (and dentists) in New York City, and the only thing that they could come up with was an extraordinarily high SED rate (3x times the upper normal limit) and elevated ANA (autoantibodies) - no diagnosis, no path, no options, nothing. Just a genuine- “wow- you must really feel awful I’m so sorry” - and on to the next doctor.

One of the doctors prescribed me a steroid hoping it might help tame some of the inflammation. Although it absolutely helped many of the symptoms, 4 days in, I had my first, and what I hope will be my last, suicidal ideation ever. I thought to myself so clearly: how do people live like this?

I snuggled in next to my husband and looked across the hall at my little baby girl’s door and decided in that moment that I was going to stay put - whatever it took.

The turning point.

A few torturous days later, a gut microbiome test that my functional doctor ran on a whim - the “GI Map” - had finally come back.

It came back lit up like a Christmas tree.

FINALLY, something to work from.

I started down the rabbit hole of microbiome and gut health (functional health) that day and have never come out - and I never really plan to. Every new thing I learned and implemented from a smart practitioner, researcher, personal experience, mentor, or my addiction to Pub Med got me one step closer to fully healthy.

About a year in, I started formally helping my friends and family - and went back to school to collect as many pieces of this puzzle that were out there to find…

What Healing Looked Like

Three years later,I have no gut symptoms.

Ninety-seven percent of my previous symptoms are gone, like they never happened. I don’t get sick all the time anymore - in fact, hardly ever - and it comes and goes quickly when I do, even as a preschool mom. Believe it or not, I’m much less emotionally sensitive.

I can even tolerate gluten again! 

I’m still building my resilience, relaxing my ‘Type A’ tendencies (yeah, they’re a giant part of this conversation), and am in a couple of specialty biomechanical therapies for my IMPROVING posture and scoliosis. My translucent teeth largely filled back in on their own.

Most importantly, I am present. With my beautiful 3 ½ year old daughter. With my wonderful, smart, and funny as hell, not-at-all ‘Type A’ husband (so jealous ;)). With myself. In a way I never have been before…

Fully alive.

And it wasn’t just me…

My mom, who’s been on this journey with me, is healthier at 72 than she was at 42. No clinical signs of Hashimoto's or Fibromyalgia left - the two named conditions that plagued her for the better part of her adult life. She weaned way down on her thyroid meds, lost 60 pounds without trying, and she weaned off 100mcg of Fentanyl and all her other opioid medications for Fibro last year. She now has a Widespread Pain Index (WPI) pain score of “0”. 

I got into this field to help myself and my family. Now, I’m thrilled to be able to help others!
