L am 58 can i get cystic fibrosis at that age.

No: You are born with cystic fibrosis, you don't "get" it later in life. It may not be diagnosed right away depending on the type and severity of symptoms. For example, a newborn with an intestinal blockage would be picked up quickly, but an older child or even an adult who presented with mostly sinus symptoms might not get diagnosed until later.

Yes and No: Cystic fibrosis, cf, is a genetic disorder and is present from birth. However, in mild forms of CF it may not cause many symptoms or be diagnosed until adulthood. Te diagnosis is based on sweat testing or genetic testing. Although uncommon, cases of CF can be diagnosed at your age.
