Cystic fibrosis is a disease that is inherited by children from their parents. For a person to have cystic fibrosis, two copies of the cystic fibrosis gene have to be inherited, one from each parent.
Cystic fibrosis leads to the accumulation of mucus in vital organs like the lungs, the pancreas and the digestive system. This leads to the lungs getting inflamed which does not allow the patient to breathe normally. The collection of mucus in the pancreas and the digestive system does not allow normal production and distribution of enzymes which inhibits digestion. To manage the effects of cystic fibrosis, patients have to take synthetic enzymes with their food.
Some symptoms of cystic fibrosis are frequent lung infections, difficulty in breathing, a salty tasting skin, poor growth and difficulty in bowel movements.
