Histamine Flares Before Your Period? How Bile, Estrogen & Mold Trigger Symptoms

If your histamine symptoms flare right before your period, you’re not imagining it.

It’s likely not “just hormones.”

It’s your bile.

Here’s the deal: estrogen is detoxed through your liver and sent out in bile. 

But when bile isn’t flowing properly — due to mold, stress, or gut issues — estrogen builds up. And built-up estrogen…

🧬 Triggers mast cells
🧬 Lowers DAO (the enzyme that clears histamine)
🧬 Drives even more histamine flares

What can slow bile flow?

• Mold toxins

• SIBO or candida

• Low-fiber or low-fat diets

• Estrogen dominance itself

What you can do about it:

• Support bile with taurine, glycine, and magnesium

• Use bitters (lemon peel, arugula, dandelion)

• Do castor oil packs

• Eat enough fat (esp. omega-3s and phosphatidylcholine)

• Address the root: mold or gut toxins

This is one of the first things I assess with my clients — especially if they’re doing “all the right things” but still flaring.
