Introduction
Triglycerides can cause pancreatitis, and elevated triglyceride levels constitute a form of hyperlipidemia. In addition to promoting atherosclerosis, triglyceride levels exceeding 5.6 mmol/L may trigger acute pancreatitis—specifically, hypertriglyceridemic pancreatitis. This occurs because elevated triglycerides are hydrolyzed by pancreatic lipase into large amounts of free fatty acids, leading to acidosis and subsequent damage to the microvasculature of the pancreas.
Triglycerides are a fundamental component of lipid profile testing, commonly reported in routine blood test results. Elevated triglyceride levels may indicate an increased risk of atherosclerosis. Moreover, severely elevated triglycerides can trigger pancreatitis or severe hepatitis. Therefore, preventive measures targeting the underlying causes are essential to avoid complications. But why do elevated triglycerides cause pancreatitis?
Why Do Elevated Triglycerides Cause Pancreatitis?
Elevated triglycerides can induce pancreatitis; hypertriglyceridemia is a form of hyperlipidemia. In addition to its association with atherosclerosis, when serum triglyceride levels exceed 5.6 mmol/L, they may precipitate acute pancreatitis—specifically, hypertriglyceridemia-induced pancreatitis. This occurs because elevated triglycerides are hydrolyzed by pancreatic lipase into large quantities of free fatty acids within the pancreas. These free fatty acids induce metabolic acidosis, damaging pancreatic microvessels and promoting microthrombus formation. Consequently, pancreatic microcirculation becomes impaired, ultimately leading to acute pancreatitis. If triglyceride levels remain persistently elevated, recurrent episodes of pancreatitis may occur, rendering the condition refractory to treatment.
Pancreatitis is managed through fasting, antibiotic administration, intravenous fluid resuscitation to prevent shock, and nasogastric tube decompression or continuous gastrointestinal decompression to prevent vomiting and aspiration. Prokinetic agents may be administered to alleviate abdominal distension. Early broad-spectrum intravenous antibiotics—or selective gut decontamination with antibiotics—are recommended for severe pancreatitis complicated by pancreatic or peripancreatic necrosis, to prevent bacterial and fungal infections arising from intestinal bacterial translocation.
In daily life, patients should ensure adequate rest, avoid fatigue and sleep deprivation, quit smoking and alcohol consumption, maintain regular dietary habits, and refrain from overeating or binge eating. We hope this information proves helpful to you.
