How long (days, weeks, months) does lipase stay elevated from onset of acute or chronic pancreatitis? is lipase elevated at end stage of pancreatitis?

Lipase: The lipase level is usually elevated in acute pancreatitis, and usually not in chronic pancreatitis. It will usually remain elevated as long as the acute pancreatitis remains active, and usually decreases as the pancreatitis improves. This can take weeks, but usually does not. A lot depends on what is causing the pancreatitis, in addition. Good luck.
