The severity of complications varies based on the type of pancreatitis. In cases of acute pancreatitis, most people recover fully over time without lasting effects. While many patients achieve complete recovery, a small number may form fluid collections around the pancreas, requiring medical drainage. Conversely, chronic pancreatitis might eventually resolve, but it usually takes a longer time and follows multiple episodes. This form of pancreatitis is more prone to ongoing complications, including diabetes, weight loss, persistent pain, and an increased risk of pancreatic cancer.
