Mast Cell Activation Syndrome (MCAS) is a complex condition in which the body’s mast cells become hypersensitive, releasing excessive or inappropriate levels of chemicals such as histamine in response to triggers that are typically harmless. This overreaction can lead to a wide range of symptoms—from skin rashes and digestive discomfort to fatigue, brain fog, and even heart palpitations.
Triggers vary widely and may include certain foods, environmental exposures, or even stress. Although MCAS can be difficult to diagnose and manage, targeted nutritional and lifestyle strategies can offer helpful solutions. In this week’s blog, we will explore some of the underlying causes, common symptoms, and practical approaches to managing MCAS.
