Cystic fibrosis is a genetic respiratory disease. It is caused by a defective gene that creates thick and sticky mucus that clogs up tubes and passageways. It is a hereditary disease which affects lungs and pancreas. People with cystic fibrosis will have shorter life span and it is life threatening. The mucus of cystic fibrosis causes dangerous, lung infections as well as obstructions in the pancreas. This prevents important enzymes from breaking down nutrients for the body. Symptoms of cystic fibrosis includes salty-tasting skin, poor weight gain in spite of excessive appetite nasal polyps, or small, fleshy growths found in the nose greasy, bulky stools chronic cough, frequent lung infection, a poor growth rate in children and salty-tasting skin. The disease is diagnosed by immune reactive trypsinogen test, Sweat Chloride Test, Sputum Test, Chest X-Ray, CT scan, pulmonary function tests. Treatment include antibiotics which is prescribed to get rid of lung infection, Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and indomethacin, may help reduce any pain and fever associated with cystic fibrosis. Bronchodilators increase the airflow to the lungs by relaxing the bronchial tubes. In severe cases lung transplant involves removing a damaged lung and replacing it with a healthy one.
