What is MCAS?
MCAS is a medical condition where immune cells called mast cells become overly active and release chemicals that cause severe, repeated allergy-like symptoms.
Mast cells are part of your immune system, but when they start overreacting and releasing inflammatory mediators too easily, it can cause a whole range of symptoms. People with MCAS often experience:
Chronic fatigue and brain fog
Gastrointestinal issues (bloating, diarrhoea, reflux)
Flushing, rashes, and itching
Headaches and migraines
Anxiety and heart palpitations
Reactions to foods, stress, or environmental triggers
The tricky part? MCAS is often missed or attributed to something else such as allergies, IBS or anxiety.
Our new Integrative GP Dr Jess works with MCAS patients, she's interested in understanding why your mast cells are activated. Is it your gut microbiome? Chronic stress? Environmental exposures? Nutritional deficiencies? She will then address those root causes. If you'd like to know more about working with Dr Jess please reach out to Reception on 4077 3803.
