Mast Cell Activation Syndrome (MCAS) Treatment in Portland, OR

We Treat MCAS and Histamine Intolerance by Addressing Triggers, Inflammation, and Immune Imbalance

Understanding MCAS: A Complex, Systemic Condition

We Provide Expert Integrative Care to Calm Immune Reactivity and Restore Health

Mast Cell Activation Syndrome (MCAS) is a chronic, multisystem disorder caused by overactive mast cells releasing excessive inflammatory mediators such as histamine. These reactions can result in a wide range of debilitating symptoms that affect the skin, gut, respiratory system, cardiovascular system, and nervous system. At Restorative Health Clinic in Portland, Oregon, we offer personalized, root-cause-focused care to help patients with MCAS find lasting relief and improved quality of life.

Mast cells are a vital part of the immune system, defending the body from pathogens and environmental toxins. In MCAS, these cells become hypersensitive and release large amounts of mediators—even without clear threats—triggering widespread inflammation and dysfunction.

Diagnosing MCAS can be difficult, as symptoms mimic other conditions. However, with expert evaluation and a comprehensive approach, effective treatments are possible.
