Mast Cell Activation Syndrome (MCAS) is a Shapeshifter

Do you have mystery symptoms that no one can figure out? 

Do you have extreme sensitivities to foods, medications, and supplements that other people don’t have? Or perhaps you have hold your breath to walk down the laundry aisle at the grocery?

Do you suffer from gut issues, sleep problems, brain fog, heart palpitations, or constant exhaustion?

Maybe you’re battling fibromyalgia like pain, rashes, hives, itching, headaches, or swelling?

If so, you might have Mast Cell Activation Syndrome (MCAS). Roughly 9-17% of the population has MCAS, and it manifests a little bit differently for everyone – like the least fun shapeshifter ever.

What are Mast Cell Activation Syndrome (MCAS) and Histamine Intolerance?

Mast Cell Activation Syndrome, or MCAS, occurs when mast cells – aka the frontline sensing and defending cells of your immune system – become overly sensitive and overly responsive, flooding your body with inflammatory mediators like histamine that can cause widespread symptoms in your body. Histamine Intolerance is a related condition to MCAS in which your body can’t handle the amount of histamine in your system.

The good news is you CAN recover from MCAS and Histamine Intolerance. You just need to identify the causes for mast cell overstimulation, remove the offending triggers, and stabilize your system so you can begin to heal.

At the Reversing Mast Cell Activation and Histamine Intolerance Summit, happening October 18 – 25, 2022, you’ll learn how to recover from even the worst case of MCAS and HI. You’ll learn from more than 40 experts in Mast Cell Activation Syndrome (MCAS) (including doctors, functional medicine experts, chronic illness specialists, and more) how to avoid the worst triggers, reset your immune system to heal, and reclaim your life without sensitivity or autoimmunity.

Reclaim the old you at the Reversing Mast Cell Activation and Histamine Intolerance Summit.
