Okay, my pft's have been going down for like 7 years now, (I'm 25) but much more since 03. I have steadied them that past year or two but they are still low. I'm really on a mission to try to raise them, hopefully 10 percent (FEV1) by my next appt. in May. I've gained weight, as adding nutrition should help, I'm also doing airway clearance 3-4 times a day (flutter, pep, vest). I also exercise about 20 minutes a day (aerobic) and am trying to start with lifting weights. I don't feel well enough to try the OO, and I know my doc wouldn't approve at this point. I've never been able to gain weight and with hard work I'm doing that now. My next goal is to raise the pft's. I'm just looking for some suggestions. What has worked for you?
