My 21 yr son has episodes of vomiting and upper abdominal pain. MRI showed mild diffuse periportal edema, abdominal ascites, possible asymmetric perfusion of left hepatic lobe. His heart rate is low 40 s. He played sports in high school but occasionally swims, plays basketball, lifts weights currently. He is 6 2 and weighs 140 lbs. In the last 1 1/2 year he went from an athletic 180-190 lbs. He has been at 110 lbs at his lowest last year. He cannot eat glutten but has not been diagnosed celiac.
