Hello all. Just wanted to see whether other people with lung conditions have experienced changes in their sense of smell as their lung issues developed. I have alpha 1 antitrypsin deficiency (zz) and shortly before I learned of this I noticed my sense of smell changing. This seems to have come on quite suddenly in the past few months. I used to love the smell of cut grass but half way through this summer I realised it had started smelling very unpleasant - sort of acidic - to the point where I now wear a mask to mow the lawn! On the other hand i could barely smell the fragrance from the roses in my garden this year. Around the same time as the grass problem my cats' food (all wet varieties) started smelling really strong and odd - in an acidy sort of way. I also noticed some perfumes and deodorants smelled unpleasant. At first I thought it could be because of a cold I had a while back but that's long gone and the smell issue has persisted. I have normal spirometry results for my age though I've recently been experiencing breathlessness on exertion. I'm not on any medication. After asking about this on the Alpha 1 website several people mentioned they had experienced issues with their sense of smell, I wondered how widespread it might be amongst people who have COOPD unrelated to Alpha 1?
