The normal range for triglycerides is between 0.45 and 1.7 mmol/L. Studies have found that elevated triglycerides are one of the risk factors for coronary heart disease. If triglycerides are 6.8 mmol/L, it is severe hypertriglyceridemia, which is relatively serious, especially if the blood lipids are high for a long time, which can lead to the development of fatty liver, pancreatitis and cirrhosis. Excessive triglycerides also lead to functional changes in fat cells and increased blood viscosity, increasing the risk of cardiovascular diseases, such as coronary atherosclerosis and cerebral infarction. If a patient has hypertriglyceridemia, it is important to identify the cause of this condition, such as whether it is due to hypothyroidism, or Cushing’s syndrome or nephrotic syndrome. In this case, medication intervention is required. Common triglyceride-lowering drugs include fibrates, omega-3 fatty acids, niacin and its derivatives, and usually fenofibrate, one capsule per day, which can effectively lower triglycerides and is more effective when taken with a meal. In patients with familially inherited hypertriglyceridemia, it is possible that lifelong use of lipid-lowering medications may be required to bring the lipids down to within the standard range. In addition to medication, patients need to control their fat intake and exercise appropriately.
