Overview

Cystic fibrosis is a recessive genetic disorder that can lead to serious complications or even put your life at risk. It may cause severe problems in the lungs, pancreas, liver, and intestine. It is an inherited disorder, and affects cells that produce mucous, sweat, and digestive juices.
A faulty gene causes your mucous to become thicker and stickier and this clogs up glandular secretions. The damage usually affects the lungs and the pancreas, and it is a life-threatening disorder.
According to Kumar and Clark (Sixth Edition), previously people with cystic fibrosis would not live past the age of 20. However, in recent years, better methods of checking and managing complications of the disease allow patients to live into their 50s or even longer.
