Cystic Fibrosis is a hereditary disease that affects the entire body and can cause serious physical damages and early death. First recognized in the 1930's, the name "Cystic Fibrosis" refers to the characteristic of fibrosis, tissue scarring being present" and a cyst forming on the pancreas. It is known as the most life-shortening inherited diseases which affects children at an early age. Cystic Fibrosis is caused by a mutated gene called the Cystic Fibrosis Trans membrane Conductance Regulator or CFTR and assists in creating sweat and mucus. Though most people without Cystic Fibrosis have two working copies of the CFTR gene, only one is needed to prevent being diagnosed with CF. It develops when either gene is working properly, so the disease is considered an autonomic recessive disease. Common symptoms of Cystic Fibrosis are difficulty breathing and an inefficient enzyme production in the pancreas. Other symptoms are a thick mucous production, low immune system results in frequent lung infections, sinus infections, poor growth, diarrhea, and potential infertility which is mostly affected toward males with CF by 97%. Often, symptoms of Cystic Fibrosis are shown in infancy and childhood and include failure to thrive, and recurrent lung infections. The most efficient aspect of the CF therapy is limiting and treating the lung damage caused by thick mucus and infection with the goal of the patient having a normal quality of life. The antibiotics are used to treat the chronic and acute infections and the mechanical devices and medications meant to be inhaled are used to clear up thickened mucus within the body. Cystic Fibrosis therapy also involves the treatments for diabetes, pancreatic disease which uses an enzyme replacement, and new reproductive techniques for those who are infertile. Also to aim for a cure in Cystic Fibrosis, therapies include transplants and gene therapies.
