It depends on what type of pancreatitis it is. If it is a mild acute pancreatitis, it will not affect the patient’s life expectancy if it does not leave any sequelae and has a very good prognosis after being cured. The life expectancy of the patient can be about 70-80 years old according to the average life expectancy. If severe pancreatitis can be saved after active resuscitation treatment, most patients will have varying degrees of pancreatic insufficiency, and very few will evolve into chronic pancreatitis. The presence of pancreatic insufficiency will affect the life expectancy, which may be 10 years or decades, depending on the severity of the disease and the patient’s cooperation with treatment. In the case of chronic pancreatitis, it is not easy to cure, and often the patient dies due to complications. Therefore, it is recommended that patients with pancreatitis should be diagnosed and treated early to avoid complications that could affect their life expectancy.
