No family members known to have had it. Being refered to Ear, Nose & Throat specialists.Thank you


Yes, patients with cystic fibrosis (CF) can be diagnosed in adulthood. First, the majority of patients with CF (based on the CF registry data) have no known family members with the disease. Depending on the data, 6% to 8% of patients with CF are diagnosed as adults. Frequently these patients have milder symptoms, sometimes referred to as “non-classic” CF, and tend to be better nourished with better-than-average pulmonary function and an overall more subtle clinical presentation. It is not uncommon for these patients to be referred for testing by Gastroenterology, Allergy and Otolaryngology specialists who see the recurrent symptoms.
