The Celia artery supplies blood to the organs in your upper abdomen. When the artery is pressed on, pinched (stenosis) or totally blocked (occlusion), it can cause pain in the upper stomach area, pain after eating, weight loss, bloating, nausea, vomiting, and diarrhea.
If needed, your doctor may perform surgery to free the ligament pressing on the artery and restoring normal blood flow.
