Repeated attacks of pancreatitis will form chronic inflammation and turn into chronic pancreatitis. Chronic pancreatitis is a serious disease in which the damaged pancreas cannot fully break down proteins and fats, causing malnutrition in the body, and long-term lack of nutrition will cause the body to lose weight, weakness, and reduced immunity. If left untreated, the damaged pancreatic tissue will become necrotic and involve multiple organs of the body, combining peptic ulcers, upper respiratory bleeding and other complications, and in severe cases, circulatory failure, heart failure and respiratory failure may occur. Patients with pancreatitis must undergo thorough treatment to avoid recurrent attacks that could cause more damage to the body.
