Triglycerides above 5.65 mmol/L are dangerous, and elevated triglycerides are a risk factor for atherosclerosis. If triglycerides are significantly higher than 5.65 mmol/L, the risk of pancreatitis is significantly higher. Pancreatitis is a very dangerous disease, and acute pancreatitis can cause self-digestion of the pancreas, leading to pancreatic edema and necrosis, which can be life-threatening in severe cases. After finding an increase in triglycerides it is recommended to eat a low-fat diet, reduce the intake of grains, increase physical exercise, control body weight, quit smoking, limit alcohol, maintain a good state of mind, eat more fresh vegetables and fruits, and try to keep triglycerides within the normal range. If the triglyceride level is significantly higher, reaching above 5.65 mmol/L, it is recommended to take oral fenofibrate or gemfibrozil and other drugs to reduce triglycerides as soon as possible to avoid the risk of acute pancreatitis.
