Yes, it’s hereditary in my family too. I really had no symptoms except a dry cough which my Dr at the time didn’t think it was anything to worry about. I changed Drs to one whose practice was mostly patients over 65. He heard me cough just one time and immediately sent me for some tests which confirmed I have IPF. I can’t tell you how many Docs I mentioned my cough to and none thought it was worth checking out. I then remembered that my sister had a similar cough. Her Doc tested her and found she also had IPF. 🙁 We both grew up with an incredible amount of smoking in the home, not sure if that’s a factor. Sadly, both my parents died young from lung cancer. Guess they just didn’t know how dangerous smoking was til much later. I don’t know if there’s any connection. between smoking and IPF but I wouldn’t be surprised if there was.
