The causes of elevated serum triglycerides are as follows: 1. Physiological elevation, such as triglycerides may be high the day after drinking alcohol, and triglycerides may also be high when blood is checked after meals, which is called physiological elevation; 2. Pathological factors lead to elevation, such as familial hypertriglyceridemia, and familial mixed hyperlipidemia. Some secondary diseases, such as diabetes, glycogen accumulation, nephrotic syndrome, coronary atherosclerosis and other diseases can also cause elevated triglycerides. In addition, when acute pancreatitis occurs in a high-risk state, triglycerides are also significantly elevated, often greater than 11.3 mmol/L, and depending on the serum status, the serum can be very cloudy. Elevated triglycerides alone are not an independent risk factor for coronary artery disease, and are only clinically more relevant if they are accompanied by elevated cholesterol and elevated LDL, along with reduced HDL.
