hi Clare....Billie here. these tests were done after feeding tube... MRI stomach, Upper GI (thru tube), stomach x-ray,etc. still haven't found causw for my rapid weight loss (44 lbs in 3 mos,and still losing). These particular tests were done as aftermath of FT placement.....so it's onward-thru-the-fog to find the problem. Thanks much for caring, it's real comforting to know that some people know and understand our situation. Regards and BFN
