Adults diagnosed with cystic fibrosis usually are found to have delayed symptoms in cf and therefore have more atypical symptoms which may have been the cause of the late diagnosis. Research has shown that people with late diagnosis demonstrate fewer complications, less serious lung disease, and a lower incidence of pancreatic problems. individuals who are diagnosed as adults usually have less typical symptoms with fewer complications, fewer lung infections and lower rates of pancreatic problems. An adult diagnosis is often referred to as delayed cystic fibrosis. Cystic fibrosis is a complex, chronic disease that primarily affects the lungs and digestive system. More than 30,000 children and adults in the united states have cf (70,000 worldwide). People with cf inherit two copies of a defective gene-- one copy from each parent -- that produces a faulty. adult-diagnosed cystic fibrosis patients generally have a milder form of the disease than that of those diagnosed in childhood however, less is known about their prognosis and life expectancy. Researchers reported the outcomes of a retrospective cohort study of 362 adults diagnosed with cystic fibrosis at age 18 years or older. Cystic fibrosis is an inherited chronic disorder that causes mucus in the body to become thick and sticky. This glue-like mucus builds up and causes problems in many of the bodys organs, especially the lungs, which can lead to infections, and the pancreas, making it difficult to properly digest food. Adult cystic fibrosis cystic fibrosis is an inherited condition characterized by the production of thick sticky mucus by the mucus glands in the lungs, intestines, liver and pancreas. The condition is most often diagnosed in children or young adults but occasionally, relatively mild symptoms may lead to frequent misdiagnosis or no diagnosis at all unless. cystic fibrosis (cf) is most often diagnosed in childhood, but older people and those with rare forms of the disease may not be diagnosed until well into adulthood. Most of these people are older children or adults who have a single symptom common to cf such as sinus or lung complications, chronic pancreatitis, or male infertility. aging of cystic fibrosis more adults diagnosed growing number have delayed onset of deadly lung disease below x jump to discuss comments below discuss.
