Amylase and Lipase levels indicate issues with your pancreas. The tail of the pancreas is on the left side. You sound like you may have pancreatitis but not sure why someone has not done further testing well before this. The weight loss and ongoing symptoms would be worrisome. Hopefully you are not anemic. If they do the standard tests it would be included in your CBC. You have a lot of the symptoms of pancreatitis but for a yr going through this I am surprised you are not sicker than you are. Where do you live? I can not imagine a doctor not following through when seeing a high Lipase level doing a CT Scan of your abdomen right away. I hope you find your answers soon. I am sure they did an Amylase they usually are done together.. If not get one..and I would certainly question my doctor as to why this has taken so long to get other diagnostic tests to find the answer. Please let us know how you do. I am pretty sure it is your pancreas that is causing issues. Are you a diabetic? Do you still have your gallbladder? Any digestive issues like peptic ulcer?
