The MAIN effect of CF is the overproduction of a thick, sticky mucus. Which creates clogging of the lungs, as well as the lack of the ability of pancreatic enzymes to flow freely, or be released at all. These are the enzymes in people without CF that break down fats, proteins, and carbohydrates. The systems which suffer the most due to Cystic Fibrosis are the digestive system, and the pulmonary system. But, various other systems suffer as well such as the endocrine system, the muscular-skeletal system, and even the reproductive system. All of these manifest in very different ways, but they are all detrimental to the life of a person with CF. These maladies are responsible for creating perhaps the most intimidating aspect of CF, which is the short life-span, as CF is a terminal illness. This made even worse by the fact that Cystic Fibrosis is a progressive degenerative disease, meaning it only gets worse, it doesn’t get better. Finally, and maybe made obvious from the aforementioned terminology there is no cure for CF.
