maybe pancreatitis? I had that, went to the hospital. I was very constipated, couldn't eat, and lost a lot of weight. I had ultrasound, endoscopy, colonoscopy and another scan. They can test your blood for lipase levels. I think 0-140 is normal. Mine was 1,000. I'm no doctor but I would definitely check to see if it's pancreatitis, it sounds similar to what I had/have (still recovering slowly). Good luck jazzy and best of health to you.
