Ever heard of MCAS?
It stands for Mast Cell Activation Syndrome, a condition where your immune system’s mast cells go into overdrive, releasing too many chemical mediators (like histamine) when they shouldn’t.
The result? Widespread inflammation and symptoms that can hit multiple body systems:
• Flushing, itching, hives
• Gut pain, bloating, diarrhoea
• Brain fog, headaches, anxiety
• Rapid heart rate, dizziness
• Breathing issues, wheezing
• Joint and muscle pain
Because MCAS looks different in everyone, it’s often missed or misdiagnosed.
If this sounds familiar, you’re not alone — and help is possible.
