my story with histamine intolerance & thyroid disease

As we start this journey together, I want you to know that helping people on their health journal is personal to me in the same way that it may be to you.

Those of you who know a little bit about my story from my first book, The 30-Day Thyroid Reset Plan, or elsewhere, will remember that for many years, I suffered from thyroid issues that were driven by gut issues, heavy metals and viruses.


is that one of the most significant issues in addition to my thyroid symptoms and my general ill health was mast cell activation syndrome, and therefore, histamine intolerance.

As a kid, I had terrible heat intolerance. I would often faint in the sun, and get hives out of the blue. When I ate certain foods that contain histamine, my scalp would tingle and a heavy fatigue would wash over me.


Later, I also experienced gradually-worsening symptoms like migraines, vertigo, heart palpitations, anxiety and panic attacks, acid reflux, a skin condition called seborrheic dermatitis and low blood pressure.

Those symptoms never went away.

Those symptoms never

In fact, in my early twenties, when the thyroid and gut issues were at their worst, I couldn’t eat almost any food without my body reacting to it in a negative way. Yet a histamine intolerance diagnosis was still almost a decade away.

Luckily, my situation improved a great deal when I was diagnosed with thyroid and gut issues. Thanks to functional medicine, I was able to heal my gut and balance my thyroid and adrenal hormones, and eat a wider variety of foods.


However, I would still experience strange symptoms no one could explain for years.

It wasn’t until I was 32, and began learning about histamine intolerance as a functional medicine practitioner that I finally began to piece together the puzzle. That led to a life-changing diagnosis: I realized that my symptoms and food sensitivities were being driven by histamine intolerance that was brought on by some genetic mutations, like MTHFR, methylation issues and other underlying causes.

From there, I began following the plan outlined in my histamine book and virtual program I use with my patients, continued to work on my health, and now, I’m able to eat most foods without any problems at all. Most of the symptoms I suffered through are gone and I live a pretty normal life day to day.

My hope for you, is that you will discover which foods & other underlying issues may be causing issues for your body, so you can experience relief from the puzzling and debilitating symptoms of histamine intolerance, thyroid issues & more.
