Resources: Quick guide to ... cystic fibrosis

1 People with cystic fibrosis (CF) have been born with a defective gene. Their airways, digestive system and other organs are at risk of obstruction from a thick, sticky mucus. The result is a tendency to suffer chronic infections and inflammation in the lungs and difficulty digesting food. Severity can vary - so always respond to the individual. Don't make assumptions about their condition or day-to-day state of health.

2 Drug regimes can be pretty aggressive, including frequent courses of serious antibiotics, sometimes administered intravenously. Many use nebulizing equipment, converting liquid medicine into a fine breathable spray. Enzymes may be taken to help digestion. Many people with CF will have a daily regime of physiotherapy, designed to help clear the lungs of mucus, or the regime may be a series of regular breathing exercises.
