I want to first say I'm not a doctor. I have chronic pancreatitis due to a botched ERCP. A normal lipase level is between 0-169 u/l. So if your lipase level is 104 u/l I'd say that's normal. The doctors here won't consider treating pancreatitis unless your lipase is 3 times the normal. I've read that is the norm. I've been told an MRI or EUS doesn't diagnose pancreatitis but diagnoses the possible cause if you have pancreatitis such as masses in the pancreas, stones or defects in the bile ducts. They also use those test to diagnose pancreatic cancer. I've never heard of Omeprazole as a treatment for pancreatitis, rather I believe that's for reflux/heartburn. There are long term side effects that can happen with reflux drugs so ask your doctor if you should change meds. Once side effect is loss of bone density. For my pancreatitis I take Creon. You asked if you have pancreatitis. Your doctor should be able to answer that. When you have a pancreatitis attack you know it. The pain, for me was in the upper right to center abdominal quadrant just under the bottom rib and radiated to the back and is excruciating. If you have this pain you should go to the ER so they can run the labs for pancreatitis and treat the pain. Pancreatitis can be dangerous. Be your own advocate, do your research and take care. Hope you feel better.
