She thinks theses are what are giving me breathing difficulties and has given me ventolin accuhaler and cetirizine tablets for when I get a reaction. She also wishes my other consultants would stop being narrow minded. It was nice to be believed today. Even though I do not wheeze.

Interesting results I have to avoid sulphites for my other health condition Interstitial cystics as they irritant my bladder. Does that mean you can't eat things with preservatives in like bacon or process meat? I can't go near sausages or bacon. Alternative are out there like quorn sausages if this is the case.


i have no idea yet. i have just been given an information leaflet. it does not mention bacon. i already knnow i cannot eat sausage my lips swell every time and i struggle with breathlessness.


I don't wheeze either, but not every asthma sufferer does; the test is whether it is reversible with Ventolin. Interesting that you have allergies to food preservatives; I was deemed to be allergic to cats, though never kept one, but do have late onset asthma, probably deriving from 50 years of hayfever (mainly grass pollen). By the way, sulphur dioxide is a major air pollutant (causes acid rain) - you might well wish to avoid going out in areas/days of high atmospheric pollution.
