"How do I know if my gut or liver is involved in my Allergies?"

Someone emailed me this after a recent talk, where I shared how chronic allergies and histamine symptoms often stem from deeper issues in the gut and liver. It’s a brilliant question—because it’s rarely talked about in conventional allergy care.

If you’re reacting to everything and antihistamines are no longer cutting it, there’s a strong chance your gut or liver (or both) are involved.

Why Your Gut Matters

Over 70% of your immune system lives in the gut. If your gut lining is inflamed or your microbiome is out of balance, your immune system becomes over-sensitive, reacting to harmless things like pollen, food, or smells.

Your gut is also responsible for breaking down histamine. If the enzyme that does this (DAO) is low—or if the gut lining is damaged—histamine builds up in your system.

Signs your gut may be contributing to allergies:

• Bloating, gas, or irregular bowel movements

• Reacting to fermented foods, wine, or cheese

• Brain fog, mood swings, or fatigue after meals

• Skin issues like itching, hives, or rashes

• Ongoing food sensitivities or intolerances

How the Liver Gets Involved

Your liver plays a key role in clearing histamine, toxins, and inflammatory chemicals. If it’s sluggish or overwhelmed, histamine clearance slows down—and symptoms worsen.

Clues your liver might need support:

• Sensitivity to alcohol, caffeine, or chemical smells

• Waking regularly between 2–4am

• PMS, skin issues, or feeling puffy and foggy

• Fatigue despite eating well

Here’s the thing:

Long-term antihistamine use might give temporary relief, but it can actually make things worse. These medications can impair digestion, dehydrate the gut lining, disrupt the microbiome, and burden the liver—worsening the root issues behind histamine overload.

That’s why instead of chasing symptoms, I recommend targeted functional testing—we can look at gut bacteria, inflammation markers, histamine load, liver function, and more. This gives us a clear picture of what your body actually needs to heal.

If you’re stuck in a cycle of allergy meds, brain fog, and reactions, it’s time to look deeper.
