People with cystic fibrosis
A genetic disease that afflicts over 33,000 children in North America, cystic fibrosis affects the glands that produce mucus, sweat, enzymes, and other secretions. The most serious consequences of the disease occur in the lungs, pancreas, and intestines, all of which become clogged with thick mucus. As the lungs become congested, they are especially vulnerable to pneumonia and other infections. When the ducts that normally carry pancreatic enzymes to the small intestine become clogged, difficulty in breaking down fats and protein is the result, along with other digestive problems. Abnormal amounts of salt are lost in sweat and saliva, which can lead to serious imbalances in body chemistry.
