The digestive problems can usually be treated by taking daily medications. To treat lung problems, most children with CF need to have respiratory therapy for about half an hour every day; this helps clear mucus from the lungs. This is something the parents or other family members can do at home. Sometimes lung infections still develop. The children may need to be treated with antibiotics at home or in the hospital. However, the infections tend to become worse over time and more difficult to treat. Treatments are costly and may be burdensome without adequate health insurance.
