My wife is 71 years old. She has a problem of vomiting soon after eating. This has been going on for years. Several doctors have examined her. One doctor noticed a mass from the stomach to the liver. A surgical procedure was performed. The mass was benign. The liver was not touched. however part of her stomach was removed. This was two years ago. since then her vomiting has gotten worse. No one knows why. She is down to 118lbs & is 4 11. What do you suggest
