Mast Cell Activation Syndrome
Complex symptoms need careful investigation, not a quick label.
MCAS is a specific condition with established diagnostic criteria. Because its symptoms can overlap with allergies and many other health conditions, assessment needs to consider the pattern of episodes, objective clinical evidence and other possible explanations.
When symptoms involve more than one body system
Mast cells are part of the immune system and release chemical mediators during allergic and inflammatory responses. In MCAS, recurrent episodes of mast cell activation cause symptoms affecting multiple body systems.
Possible features can include flushing, itching, hives, swelling, wheezing, breathlessness, abdominal cramping, diarrhoea, rapid heart rate, low blood pressure or fainting. Experiencing one or more of these symptoms does not by itself confirm MCAS.

Your MCAS appointment
Build a clear record of the episodes and the evidence.
Your doctor may ask about:
- 01
what happens during an episode and how quickly it develops
- 02
which parts of the body are affected at the same time
- 03
possible triggers and how often episodes occur
- 04
previous allergic reactions or anaphylaxis
- 05
medicines, supplements and responses to previous treatment
- 06
existing diagnoses, including allergy, POTS or gastrointestinal conditions
- 07
previous emergency care, pathology and specialist assessments
- 08
family and wider medical history
If available, bring previous pathology, emergency department and specialist reports, a list of medicines and supplements, photographs of visible symptoms, and notes about the timing and pattern of episodes.
Depending on your history, your doctor may recommend further investigation, review an existing management plan or coordinate referral to a clinical immunology or allergy specialist.
03
MCAS cannot be diagnosed from symptoms alone
Many symptoms associated with MCAS are also seen in other conditions. Current consensus criteria require recurrent symptoms consistent with mast cell activation across more than one body system, objective evidence of mast cell mediator release during an episode, and an appropriate response to targeted treatment.
Assessment should also investigate other possible causes. The aim is to avoid both missing a mast cell disorder and attributing unrelated symptoms to MCAS without sufficient evidence.
04
Ongoing and coordinated care
For someone with an established diagnosis, care may include reviewing symptoms, triggers, medication, response to treatment and emergency planning. Your GP may also help coordinate care between specialists and address other health concerns that sit outside the MCAS diagnosis.
The role Mahila plays will depend on your clinical circumstances and the specialist care already involved.
