Hi, my great uncle lives with me and is 78 years old. he has recently become very ill for no apparent reason. all tests have shown clear and doctors have said it is from 'wear and tear'. then he went to a specialist for his problem with breathing and exhaustion. this doctoe then told him that he had cystic fibrosis. can this be? i was lead to believe and have also researched information on this and it appears to me that it can only be inherited and not just dveloped this late in life. can anybody answer this query for me?
Thanks
Thanks
