What’s Behind Histamine Intolerance?

Histamine intolerance—often misdiagnosed due to its wide range of symptoms like bloating, headaches, skin flushing, and heart palpitations—is increasingly thought to originate in the gut rather than from the immune system itself.

Emerging research reveals that individuals with histamine intolerance often exhibit intestinal dysbiosis, characterized by:

• Elevated levels of histamine-secreting bacteria such as Staphylococcus, Proteus, Enterobacteriaceae, Clostridium perfringens, and Enterococcus faecalis. 
• A marked depletion of beneficial strains like Faecalibacterium prausnitzii, Ruminococcus, and members of the Prevotellaceae family. 

This imbalance can weaken DAO enzyme function by increasing inflammation and disrupting the intestinal barrier.

Why Gut Health Matters for Managing Symptoms

Healing the gut barrier helps keep histamine confined to the intestinal tract, reducing its spillover and easing symptoms. Long-term relief calls for restoring microbial balance and strengthening the gut lining.
