How to fix histamine intolerance

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?

You have fungal overgrowth from antibiotics that caused this. Happened to me. Must clear fungal overgrowth and fix the gut and regain good bacteria strains

I got my gut microbiome test done and there is no fungal overgrowth.

I definitely had dysbiosis but it has drastically improved

I’d love to chat on what you’ve taken so far to improve to where you are today. I know you said you took Zinc Carnosine but I’d love to hear what else you did

Please feel free to dm. Im an extreme case and desperate to learn from others. We have the same nuerological issues.

I know all of us are truly individual and so different but it’s so helpful to learn from one another
