Why can severe pancreatitis lead to shock respiratory failure or death?

Severe pancreatitis can lead to life-threatening complications because the disease causes the pancreas to self-destruct. During an acute attack, the gland’s fine ductal network is damaged, allowing activated and destructive digestive enzymes to escape into the pancreas and surrounding tissues.1

These activated enzymes can enter the bloodstream and travel to other organs, including the lungs and blood vessels, causing damage similar to that occurring within the pancreas itself. This systemic spread of enzymes and the resulting tissue damage are the primary reasons why severe cases can progress to shock, respiratory failure, and death. The severity of these outcomes is directly linked to the extent of the damage sustained by the pancreas and the subsequent impact on other vital organ systems.1
