If you’re reacting to everything, feeling like your body is constantly on high alert, and struggling to get answers, you’re not alone. Many people with Mast Cell Activation Syndrome (MCAS) spend years seeking answers for symptoms that affect multiple body systems. Because MCAS can present in many different ways, healthcare providers may overlook or misattribute the condition, delaying diagnosis and appropriate treatment.
Dr. Burke specializes in medically complex and treatment-resistant cases, Her approach is compassionate, collaborative, and focused on understanding the interconnected physiologic patterns contributing to illness rather than viewing symptoms in isolation. For those seeking personalized MCAS treatment options, Dr. Burke focuses on the patient as a whole.
What is Mast Cell Activation Syndrome (MCAS)?
Mast Cell Activation Syndrome (MCAS) is a complex condition involving immune system dysregulation. Mast cells are immune cells found throughout the body that help coordinate inflammatory and allergic responses. In individuals with MCAS, these cells become overly sensitive or reactive, releasing inflammatory chemicals (including histamine, tryptase, and prostaglandins) inappropriately or excessively.
Because mast cells are present throughout multiple organ systems, MCAS can cause a wide range of symptoms involving the skin, gastrointestinal tract, cardiovascular system, nervous system, respiratory system, and more. Symptoms are often fluctuating and unpredictable. Flares can be triggered by factors such as foods, infections, stress, environmental exposures, medications, and temperature changes. Mast cell reactions are different then classic allergic reactions and therefore standard allergy testing may come back normal. Many patients with complex chronic illness spend years searching for answers before the underlying pattern is recognized, especially those who are eventually diagnosed with MCAS.

Common Symptoms of MCAS & Histamine Intolerance
Mast cell disease symptoms can vary widely between individuals and often involve multiple body systems at once. Common symptoms of MCAS can include:
- Flushing, itching, hives, or rashes
- Exaggerated reactions to bug bites
- Chemical sensitivities and environmental reactivity
- Food sensitivities and allergic reactions
- Nausea, bloating, abdominal pain, GERD, or diarrhea
- Shortness of breath, chest tightness, and wheezing
- Heart racing or palpitations
- Heat and exercise intolerance
- Dizziness, lightheadedness, and symptoms of dysautonomia
- Brain fog and cognitive dysfunction
- Sleep disturbances
- Headaches and migraines
- Muscle and joint pain
- Chronic pelvic pain and endometriosis
- Painful urination and Interstitial Cystitis (IC)
- Nasal congestion or sinus pain
- Swelling of the mouth or throat tightness
- Sensory sensitivity and nervous system dysregulation
- Anxiety, mood swings, or overstimulation
- Symptoms that flare unpredictably or seem triggered by various unrelated exposures
Because MCAS symptoms can mimic many other conditions, patients are often told their symptoms are anxiety-related, psychosomatic, or unexplained before receiving appropriate evaluation. Many patients eventually explore MCAS treatment options after years of misdiagnosis.
