Sorry about that "pulmonary exacerbation" is just the clinical term for a sudden build-up of congestion in the lungs. In my kids, it happens when one of the bacteria in the lungs gets out of control, and they need a more powerful antibiotic. Sometimes it can mean a stay in the hospital.
It is possible for a child to have CF, even though they are gaining weight and do not taste very salty. There are variant genetics that can cause CF, and they effect how the disease "looks." My children have atypical CF, so they do not have digestive issues, and gain weight fine. We never noticed any unusually salty 'taste', either. But they got chronic lung infections before the diagnosis. They were 1 and 4 at the time.
One of my children had a Sweat test result of 11, yet her genetics came back identical to her sisters (an atypical form of CF). Still, we got different opinions on whether or not it was CF. Within a year, she had cultured psuedomonas, and that ended the debate.
