My daughter was diagnosed as "probable CF" at age 39, after years dealing with intractable asthma which morphed into bronchiectasis. Meds were added to her already complex regimen, and her breathing is finally improved and exacerbations down to one or two a year. Not sure of her current med, but it took 2 years of adjustments to get her to this point. I can only imagine how different her life might have been if she was properly diagnosed in childhood, because she had years of digestive issues as well, most of which are now resolved. Since there is a genetic component, now I'm wondering if her sister should be tested as well...
