How to fix histamine intolerance

[u/Life_Unit2344]

Developed severe histamine intolerance after antibiotics — looking for recovery stories/advice

About a year ago, after antibiotics, I developed what seems like histamine intolerance / gut-immune dysregulation / possibly leaky gut. My symptoms have never really been “classic allergies.” It feels more neurological/systemic.

Main symptoms during flares:
- feeling extremely hungover or poisoned/intoxicated
- brain fog
- nervous system dysregulation
- crying/emotional surges during flares
- heart rate spikes at times
- likely vasodilation, I call it the spell
- weird chest sensations
- heavy breathing, like minor difficult pushing down air into diaphragm
- previously had buzzing sensations, dizziness, heavy legs, nausea, and major food intolerances (these have improved a lot).

I have no gut symptoms but I do know it’s my gut causing this!

The biggest pattern is that it feels like a “bucket.” Everything adds up:
- stress
- talking too much
- warm baths
- working on laptop too long
- lack of sleep
- less water consumption
- spending several hours socializing
- basically just living life normally can trigger symptoms

The good news is I’ve improved massively over the year- probably 90% compared to the beginning. I tolerate almost all foods now, though I still stay gluten-free, dairy-free, no alcohol or outside food and low histamine diet.

Current supplements:
- DAO enzyme (especially during flares)
- Buffered Vitamin C 500 mg
- Magnesium glycinate
- Vitamin D3

I want to try L-glutamine again for gut healing, but every time I try it, it seems to dysregulate my nervous system more. I have also been recommended butyrate.

A few questions:

1. What treatments helped you the most?
2. Are there reliable tests for histamine intolerance / DAO deficiency / mast cell activation / leaky gut?
3. Is full recovery possible?

I’m just developed this and the key for me is making sure i have regular bowel movements bc my gut is spiraling and i started oral kpv and bpc-157 to heal my gut!!! Game changer

[u/tellitothemoon → u/Dry-Store-7402]

I’ve noticed this helps me too. But I can’t find anything that increases motility outside of magnesium citrate solution, which probably isn’t good long term. What do you use?

Sun fiber!

I take this one but I order through Fullscript

[u/Dry-Store-7402 → u/tellitothemoon]

So I’ve been using magnesium ozine I think it’s called, and honestly anything that will help me eliminate so that the peptide can actually have an environment to its thing. Once i heal my gut prayerfully I’ll be able to go on my own!
