Histamine Intolerance & the Gut

Understanding the link between histamine overload, gut dysfunction, and chronic symptoms

What Is Histamine Intolerance?

Histamine intolerance isn’t a true allergy—it’s a condition where your body can’t break down histamine efficiently, causing it to build up and trigger a wide range of symptoms.

Histamine is a natural compound involved in:

• Digestion (released in the stomach)
• Immune responses (allergies, inflammation)
• Hormone regulation
• Brain function and alertness

When the body can’t clear histamine properly, it leads to chronic inflammation, gut discomfort, and systemic symptoms.

Key Symptoms of Histamine Intolerance

Digestive:

• Bloating, gas, or cramps
• Diarrhea or constipation
• Reflux or nausea after meals

Systemic:

• Headaches or migraines
• Flushing, itching, or hives
• Anxiety, irritability, or panic
• Fatigue or dizziness
