The relationship between weight and pulmonary outcomes in overweight and obese people with cystic fibrosis: A retrospective observational study.

As CF therapies continue to improve, an increasing number of people with CF are exceeding the CDC's normal-weight range. Gaining weight past the normal range does not appear to negatively impact pulmonary health of people with CF. If this trend of increased weight gain continues, it remains to be seen if it will eventually negatively affect lung health.
