Histamine intolerance isn’t just about food — it’s a sign your system is inflamed and overwhelmed.
Mast cells play a central role here. When they’re triggered, they release histamine and other inflammatory chemicals that can lead to symptoms like rashes, bloating, brain fog, fatigue, and anxiety. In some cases, this can progress into mast cell activation syndrome (MCAS) — where the immune system becomes hypersensitive to everything.
This overview explores how chronic inflammation, gut dysfunction, and nervous system stress all tie into histamine overload — and what patterns I often see in practice when MCAS is part of the picture.
