I'm really not sure what category to put this question under, but my husband has had two episodes of fainting during flights. The first time, I was not with him. He told me the first time he just remembered not feeling well, and then waking up having urinated on himself. He was sitting alone, so he has no idea what happened.
We recently traveled on a long flight together, and within an hour of take-off, my husband was dozing on and off, and he sat forward and started digging in the seat pocket. I asked him what he was looking for, and he said he didn't feel well. He then slumped over toward me like he fainted. I tried to sit him up, and he became somewhat rigid, with his eyes rolled back and non-responsive. He also urinated on himself again. I called for a stewardess, and a doctor and paramedic were on the flight as passengers, and were able to assist him. He came too within a minute or so, and seemed very confused. He missed a few questions that they asked him. They moved him to an area on the plane where he could lay down. He still had a very strong urge to have a bowel movement and urinate. Once he was stable, they allowed him to go the bathroom. I would say it was a good 30 mins before he seemed ok...he was slightly ill on and off for the remainder of the flight (14 hrs), however, he was very sleepy.
This really scared me. I thought he had a heart attack, stroke, etc....My husband is 38 years old, six feet one, and weighs about 240. He recently (within 6 months) was told his cholesterol is about 130+. The first episode happened about 1.5 years ago. He has a very high stress job that requires a ton of flight time. There is no history of heart disease in his family.
So, what do you think? He is trying to shrug it off, but I have insisted he go to get a stress test.
