✨ This was ME for a long time…

😴 Trouble sleeping
💓 Racing heart at night
🌙 Random night sweats

Everything looked “normal,” but my body clearly wasn’t calm.

🧩 Eventually I discovered histamine was a big piece of the puzzle.

Histamine isn’t just about allergies. It also acts as a stimulating neurotransmitter, which means when levels are high it can affect:
⚡ Sleep
❤️ Heart rate
🌡️ Body temperature

For many people, nighttime symptoms are actually a sign the histamine bucket is overflowing.

🔍 If you’ve experienced something similar, there’s often a deeper root cause worth exploring.

Moldy house status update

My favorite wallpaper, needs to be

Hoping to be done by July and we will be RAGING 💃 🪩 all summer

🍑The answer is quite possible... it’s also possible that you didn’t wipe enough but it is usually one or the other (in rare cases, hemorrhoids)

🍑Most commonly it is pinworm that causes an itchy bottom 🕳️ - and thankfully pinworm is pretty easy to eradicate.

🍑Don’t sit on it! 😅 - get that checked out/ treated!

📩 Send this to all your friends who say it isn’t a problem.

🌍 Yes, mold exists everywhere. That’s normal.

🚫 What’s not normal is living long-term in a water-damaged indoor environment with active microbial growth.

🧬 In susceptible individuals, chronic exposure can shift immune balance, increase histamine load, strain detox pathways, and contribute to multi-system symptoms that often get mislabeled as stress, hormones, IBS, or anxiety.

🧠 This isn’t about panic.

🔎 It’s about pattern recognition.

🏠 If you feel reactive for no clear reason, don’t forget to evaluate the building you spend the most time in.

Happy National RD Day out there to my fellow dietitians!

I’m not sure that I’ve ever really shared the whole picture of how I got here

But I’ve wanted to be a dietitian since I was 11

and I’m so proud of the work we do here

And I can’t wait for all of the wonderful places that we’re gonna go

At the root of my desire to be a dietitian is to help people feel like their best happiest selves

😊 We certainly use antihistamines here to support our clients, but we use them appropriately to help them tolerate other things we’re doing. They are a powerful and useful tool—but not the only tool you should be relying on.

🔎 Getting to the root cause is the most important thing you can do if you actually want lasting resolution.

💬 What have you explored or dug into to try to resolve your histamine issues?

🌿 If you’re constipated, bloated, or reacting to everything…

⚠️ The issue isn’t “you’re not trying hard enough.”

🧠 It’s that something is slowing the system down.

👇 Here’s what most people miss:

6️⃣ Support the nervous system

😮‍💨 You cannot digest in fight-or-flight.
📉 Chronic stress reduces stomach acid, slows motility, and alters the microbiome.

🧘‍♀️ Until the system feels safe, progress stalls.

7️⃣ Identify what is actually driving the slowdown

🔎 Common drivers:
• Methane-producing overgrowth
• Low thyroid function
• Estrogen dominance slowing transit
• Post-infectious changes
• Mold or immune activation

🦠 Probiotics can help —
but only once the terrain is ready.

🚫 If you’ve tried multiple probiotics and still struggle to go… that’s not a probiotic deficiency.

⚙️ It’s a motility + terrain issue.

📞 This is exactly what we evaluate inside ISN.
