Do You Have Histamine Intolerance?

Have you heard of histamine intolerance?

It’s wild how much of this I’ve been seeing inside my functional health coaching practice lately. So much so I want to let you know about histamine intolerance so you know what it is in case you may be struggling with it too.

Histamine intolerance or overload is when you have a buildup of histamine in your body which makes you less tolerant of other sources of histamine, like environmental allergies, foods with higher levels of histamine (like yogurt, saurkraut, wine, or beer).

Maybe it’s a post-COVID thing….

Or it’s related to this general increase we’re seeing in more allergies, more immune dysregulation

Or perhaps it’s been there all along, we just haven’t had a medical system that’s been able to recognize it…

Because it looks different in different people. It doesn’t fit into a nice, neat, clean box with a diagnosis code.

Just because symptoms can vary though, doesn’t make histamine intolerance any less real.

Histamine intolerance or overload and it’s further progressed, even less understood cousin –  Mast Cell Activation Syndrome (MCAS) evade our Western medical system.

These multi-faceted dysfunctions are where a functional, individualized, root cause approach is essential.

And functional medicine is likely why we’re finally getting some more understanding around the dynamic of histamine intolerance.

If you’re like me, you might associate histamine with Benadryl.

I used to hear histamine and think hives, itchy skin, watery eyes, runny nose, sneezing attacks…

You can have none of these “typical” histamine symptoms and histamine overload can be showing up in other ways.

Signs of Histamine Intolerance

  • Headaches
  • Migraines
  • Bloating
  • Diarrhea
  • Insomnia
  • Anxiety
  • Nausea
  • Flushing
  • Heart palpitations
  • Dizziness
  • Frequent illness

A quick story to illustrate…

A client noticed an increase in some of these symptoms when she traveled to Spain: nausea, flushing, headaches, bloating, diarrhea…

She texted me and immediately I thought…

Cured meats. Aged cheeses. Wine.

Histamine city.

Identifying histamine as a trigger was huge for her.

Two days later she texted me this…

How to Address Histamine Intolerance

Overcoming histamine intolerance is a matter of lowering the level in your bucket.

And working it down from both sides…

On one end – where histamine is coming from and factors that are exacerbating it. High histamine foods, gut dysbiosis, estrogen dominance can all be involved.

And on the other end – how you’re breaking down and clearing it.

We have to detox histamine the same way we have to detox toxins and hormones. And a number of things can get in the way here, like…

  • Gut inflammation that may be blocking synthesis of the DAO enzyme that breaks down histamine in the gut…
  • Nutrient gaps that may be impairing the methylation process that’s so essential for clearing histamine…
  • Constipation (blocked phase 3 detox) that means these things aren’t exiting the building…

When you focus on addressing both sides, gradually that histamine level in the bucket comes down.

And as it does, your histamine intolerance symptoms (bloating, diarrhea, insomnia, anxiety) go away.

If you’re dealing with any of these symptoms on the list above, know these things can improve and can go away all together when you address the root causes contributing to histamine intolerance.
