Severe pancreatitis can be dangerous even during the recovery period. Severe pancreatitis may be life-threatening. In hemorrhagic necrotizing pancreatitis, the mortality rate can be as high as 90%, and pancreatitis can be life-threatening when it is severe enough to lead to insufficient blood perfusion to multiple organs, which can lead to renal failure, hepatic failure, respiratory failure, and even lead to electrolyte dysfunction. Severe pancreatitis needs to go through three dangerous phases of systemic inflammatory reaction, acute infection and complication in clinic, and it is relatively safe to go through these three dangerous phases. In the recovery period, first pay attention to dietary adjustments, eat fluids when you can eat, avoid eating cold and spicy food, and avoid drinking alcohol, overeating or drinking alcohol may trigger pancreatitis, resulting in a certain risk of life. In addition, severe pancreatitis may result in impaired pancreatic islet function, which may cause secondary diabetes, such as dietary inattention during the recovery period, may result in acute complications of diabetes, such as diabetic ketoacidosis, resulting in a certain degree of life-threatening. For patients with severe pancreatitis, it is recommended to consult the gastroenterology department of a regular hospital for diagnosis and treatment.
