Like "My Father-in Law had this. It took forever for doctor's to diagnoise him. We went to specialist in Houston who wanted to put a tube in him to feed him. He was sick for six months, throwing up all the time and losing weight. FINALLY with him they found single cell lung cancer and that can cause gastropraresis too. He was 79 and passed away about 6 months after he was diagnoised. It is a terrible thing to have to live with this. I am sooooo sorry! God Bless you and take care."
