What MCAS can involve
Mast cell activation syndrome involves mast cells releasing their contents when they shouldn't, and the result is a scattered set of symptoms that rarely behave the same way twice. Flushing, hives, itching, abdominal pain, nausea, dizziness, palpitations and brain fog can arrive in different combinations, triggered by foods, smells, heat, stress or nothing you can identify.
That inconsistency is what makes it exhausting to explain. One reaction proves nothing. Dozens, written down as they happened with whatever preceded them, start to show shape. taluvu keeps that record without deciding what caused anything, which matters here more than most places, because the temptation to link a food to a flare is strong and frequently wrong.
Symptoms checklist
MCAS symptoms checklist to take to your GP
Below are some of the symptoms associated with MCAS. You can print the MCAS checklist and weekly diary and fill it in by hand.
See what applies to you, note how often it happens, and take it to your appointment, so the conversation starts further along. It describes your experience. It does not say what is causing anything: having many of these does not mean you have MCAS, and having few does not mean you do not. Only a clinician can work that out with you.

The list comes from the charity sources linked further down this page, and from what people living with MCAS tell us they keep an eye on. It is a starting point, not a test.
How a day can feel
If your days sound anything like this, taluvu was made with you in mind.
- “It's never the same twice, which is the worst part.”
- “I reacted to something I have eaten for years.”
- “People think I'm fussy. I'm trying not to flare.”
- “Perfume in a lift can end my afternoon.”
- “I have a list of safe foods and it keeps shrinking.”
These are the kinds of things taluvu invites you to say in your own words, never a checklist of what anyone “should” have.
