Mast cell activation syndrome (MCAS) is when your mast cells overreact with no known trigger. It causes severe symptoms and can lead to life-threatening anaphylaxis.
What should you know about MCAS and vagus nerve stimulation? Vagus nerve stimulation (VNS) involves electrically stimulating the vagus nerve -- the nerves responsible for rest and digestion ...
Mast Cell Activation Syndrome (MCAS) happens with repeated symptoms of anaphylaxis – allergic symptoms such as hives, swelling, low blood pressure, difficulty breathing and severe diarrhea.
MCAS is an immunological condition in which mast cells, a type of white blood cell, inappropriately and excessively release chemical mediators, such as histamine, resulting in a range of chronic symptoms, sometimes including anaphylaxis or near-anaphylaxis attacks. [2][3][4] Primary symptoms include cardiovascular, dermatological ...
In someone with MCAS, where these mediators are released too frequently, they can affect the body in multiple ways - causing multiple symptoms in different parts of the body at the same time.
The incidence and prevalence of cases with monoclonal MCAS (MMCAS) and idiopathic MCAS are not well known and there is insufficient data in the literature [11, 12].
Ultimately, though, MCAS and other forms of mast cell activation disorders can be too difficult to resolve alone. If you have or suspect you may have MCAS or something similar, you can reach out to one of our experienced health practitioners for help.
The seven root causes of MCAS include genetic predisposition, environmental triggers, chronic infections, gut dysbiosis, hormonal imbalances, autoimmune disorders, and nervous system dysregulation.
