I've been struggling to keep weight on despite eating a lot particularly since my asthma got worse. The asthma nurse has said its because I am expending so much energy breathing. I'm now 6stone 13lbs and most people laugh at me but its not funny as I have no reserves and don't look great . The asthma nurse said it was fairly common but I've never heard it before. I'm finally getting a blood test today to check for other things. I wondered if this had happened to anyone else?
