Mast Cell Activation Syndrome (MCAS)

Mast Cell Activation Syndrome (MCAS) is a complex condition where mast cells release excessive inflammatory mediators, leading to unpredictable reactions that impact multiple systems. It can feel like you’re reacting to everything.

What is MCAS? 

MCAS is a form of immune dysregulation in which mast cells become overly reactive, releasing histamine and other chemicals inappropriately. This can cause a wide range of symptoms that often appear unrelated.

What are the symptoms of MCAS? 

Symptoms can include:

  • Flushing or hives (dermatologic)

  • Nasal congestion or asthma-like symptoms (respiratory)

  • GI upset: bloating, pain, diarrhea (digestive)

  • Fatigue or brain fog (neurological)

  • Sensitivities to foods, smells, or chemicals (immune)

  • Rapid heart rate or dizziness (cardiovascular)

What causes MCAS? 

The root cause can be difficult to pinpoint and often overlaps with other chronic conditions.

  • Genetic predisposition

  • Chronic infections or toxins

  • Severe stress or trauma

  • In many cases, the cause is unknown

Prevention of MCAS 

While MCAS is not always preventable, reducing immune triggers can help.

  • Nutritionally support stabilization of mast cells (allergic cells)

  • Minimize exposure to known triggers (foods, chemicals, mold)

  • Support detoxification and antioxidant pathways

  • Calm nervous system and vagal tone
