Which pancreatic enzyme typically elevates within 3-6 hours after symptoms of acute pancreatitis and may decrease after 3-10 days?

In cases of acute pancreatitis, amylase levels are known to rise shortly after the onset of symptoms, typically within 3 to 6 hours. This elevation in amylase can be attributed to its release from the damaged pancreatic acinar cells into the bloodstream during episodes of pancreatic inflammation.

Moreover, while amylase levels can peak quickly, they also tend to return to normal relatively fast, usually decreasing within about 3 to 5 days post-episode. This quick rise and fall in amylase levels are what make it a useful marker for the diagnosis of acute pancreatitis. On the other hand, lipase, another key enzyme in this context, usually has a later peak and remains elevated for a longer duration than amylase.

Trypsin and chymotrypsin, while important digestive enzymes, are not typically measured clinically in the context of acute pancreatitis and do not exhibit the timing of elevation as distinctly as amylase does.
