MCAS Doctors in Chandler, AZ

Mast cells are immune cells found throughout the body. They play an important role in allergic responses, inflammation, immune defense, and healing.

When activated appropriately, mast cells release substances such as histamine and other inflammatory mediators to help protect the body. In mast cell activation disorders, these cells may release mediators too easily, too frequently, or in response to triggers that would not normally cause significant symptoms.

Because mast cells are located throughout the body, symptoms can affect multiple systems at once.

Symptoms vary considerably from person to person and may come and go.

Common symptoms can include:

• Flushing or feeling suddenly hot
• Itching or hives
• Skin rashes
• Nasal congestion
• Shortness of breath or throat irritation
• Headaches or migraines
• Brain fog
• Fatigue
• Heart palpitations or rapid heart rate
• Dizziness or lightheadedness
• Abdominal pain or cramping
• Bloating
• Diarrhea or changes in bowel movements
• Nausea
• Food sensitivities
• Sensitivity to medications, supplements, fragrances, chemicals, heat, or alcohol
• Feeling as though your body is suddenly reacting to “everything”

Some patients experience symptoms that overlap with dysautonomia or POTS, chronic infections, mold-related illness, and other inflammatory conditions.

MCAS can have many potential triggers, and identifying them is an important part of developing an individualized treatment plan.

Potential triggers may include:

• Certain foods or high-histamine foods
• Alcohol
• Heat or temperature changes
• Exercise
• Stress
• Hormonal fluctuations
• Medications or supplements
• Environmental exposures
• Mold or water-damaged buildings
• Viral or other infections

For some patients, mast cell symptoms begin or significantly worsen following an infection or environmental exposure.

There is no single test that explains every patient’s symptoms.

Evaluation may include a detailed medical history, symptom patterns, potential triggers, laboratory testing for mast cell mediators when appropriate, and evaluation for other conditions that may be contributing to the patient’s symptoms.

At Live Well Wellness Center, we also consider the bigger clinical picture. Depending on the individual, this may include evaluating gut health, nutrient status, hormones, thyroid function, chronic infections, environmental exposures, inflammation, and autonomic nervous system symptoms.

Treatment depends on the individual patient’s symptoms, triggers, and underlying health concerns.

A treatment plan may include:

• Reducing identifiable mast cell triggers
• Dietary changes, including a temporary lower-histamine approach when appropriate
• Nutritional and lifestyle support
• Targeted supplements
• Prescription or over-the-counter medications that help reduce histamine or other mast cell mediators when appropriate
• Gut and microbiome support
• Treatment of underlying infections or environmental exposures when identified
• Support for associated conditions such as dysautonomia or POTS

The goal isn’t simply to restrict more and more foods or avoid everything that causes a reaction. We want to understand why the immune system has become so reactive and develop a plan that helps improve overall resilience and quality of life.
