Do lipase levels of 2400 suggest severe acute pancreatitis? i do not have a gallbladder and the reasons for my recurrent pancreatitis are unknown.

This is a high: Lipase level, so, yes, i would be worried that you might have severe pancreatitis. The actual level does not correlate with severity, however, and usually an imaging study is needed to confirm the severity. Other causes are alcohol, medications, trauma, and elevated triglycerides. Consult with your doctor or GI specialist for specific advice.
