Hello, I am in the FAA, and I recently found out that I have a genetic mutation that gives me a very high probability (70%) of getting stomach cancer that is hard to detect and usually fatal. The suggested treatment for this mutation is to have a total gastrectomy - removal of the stomach. I've read that you can live a pretty normal life after surgery, just smaller more frequent meals but I am worried about how it would impact my medical clearance. Does anyone have any information on this/know anyone who has had a gastrectomy? My main concern is that if I have to eat or use the bathroom more frequently they would have a problem with me possibly sitting on position for 2 hours. Thanks.
