What physiological process does pancreatitis primarily disrupt?

Pancreatitis primarily disrupts the production of digestive enzymes due to inflammation of the pancreas. This condition leads to the activation of enzymes within the pancreas itself instead of in the small intestine, where they are usually activated for digestion. As a result, the normal breakdown of food molecules is impaired, affecting the individual's ability to digest and absorb nutrients effectively. Although pancreatitis can have secondary effects on other physiological processes, such as insulin regulation and absorption of vitamins, the direct and primary impact is on the production and secretion of digestive enzymes. This disruption is crucial because without adequate digestive enzymes, the body cannot process food effectively, leading to malnutrition and various gastrointestinal symptoms.
