Detailed explanation-1: -Symptoms may include: Thick mucus that clogs certain organs, such as the lungs, pancreas, and intestines. This may cause malnutrition, poor growth, frequent respiratory infections, breathing problems, and chronic lung disease.
Detailed explanation-2: -In cystic fibrosis, the airways fill with thick, sticky mucus, making it difficult to breathe. The thick mucus is also an ideal breeding ground for bacteria and fungi. Cystic fibrosis (CF) is an inherited disorder that causes severe damage to the lungs, digestive system and other organs in the body.
Detailed explanation-3: -About 90 percent of people with CF have sticky mucus that blocks ducts in the pancreas and prevents enzymes from reaching the small intestine to digest food.
