| About medications The respiratory and digestive systems are the two systems in the body most affected by cystic fibrosis, and are the most likely to require medication. These can be taken by mouth, given by IV (intravenously), or inhaled using a nebulizer. About nutrition Cystic fibrosis patients who are well-nourished grow better, have better lung function, and live longer than patients with poor nutrition. | | For More Information Quality Reports Information from Other Medical Websites |
