Glad to find this! After a couple of months of stomach issues and all the usual test on your stomach and colon, the doctors did a ct scan with contrast. That revealed the compression of my Celiac artery. Also revealed pulmonary emboli in my lower lung. They estimate my artery is only 30% compressed but the blood clot was adding to my problem and causing the typical weight loss, stomach pain, etc. Since I have been on blood thinners I can eat again. I am 70% better so no surgery at this point but I can tell this will most likely be an on going issue the rest of my life. Good to know this resource is available.
