Mast Cell Activation Syndrome (MCAS): An Overview
Description
Mast cell activation syndrome (MCAS) is a chronic condition characterized by the overactivation of mast cells, a type of immune cell found in various tissues throughout the body. When activated, mast cells release a variety of inflammatory mediators, such as histamine, tryptase, and cytokines. These mediators can trigger a wide range of symptoms, including:
- Skin reactions (e.g., hives, flushing, itching)
- Digestive issues (e.g., diarrhea, abdominal pain, nausea)
- Respiratory problems (e.g., nasal congestion, wheezing, shortness of breath)
- Cardiovascular symptoms (e.g., palpitations, hypotension)
- Neurological issues (e.g., headache, fatigue, brain fog)
Symptoms can vary from person to person and can be triggered by a variety of factors, including certain foods, environmental allergens, medications, and stress.
Associated Diseases
MCAS can be associated with other underlying medical conditions, including:
- Allergic diseases (e.g., asthma, eczema, hay fever)
- Autoimmune disorders (e.g., lupus, rheumatoid arthritis)
- Gastrointestinal disorders (e.g., irritable bowel syndrome, Crohn's disease)
- Neoplastic disorders (e.g., mastocytosis)
Did you Know ?
Approximately 1 in 10,000 people are affected by MCAS. However, it is often underdiagnosed or misdiagnosed as other conditions, making it difficult to determine the true prevalence.
