Serum triglyceride 2.3 is considered elevated and is more serious and potentially at risk for cardiovascular events if there are underlying diseases such as hypertension and diabetes mellitus, while it is not serious if it is simply elevated. The normal range of triglycerides is 0.4-1.8 mmol/L. Its main function is to supply and store energy, and also to immobilize and protect internal organs. Its sources are mainly categorized into endogenous and exogenous, i.e., synthesis by the human liver and fat itself and intestinal absorption of fat from food. High serum triglycerides lead to metabolic abnormalities, and several studies have shown that triglycerides are positively associated with the risk of atherosclerosis. It is also associated with insulin resistance, hypertension, fatty liver and other diseases. It also causes acute and chronic inflammatory responses and is associated with procoagulant phospholipids and thrombin concentrations. If you have an underlying disease such as hypertension or diabetes with elevated triglycerides, you will need to receive lipid-lowering therapy. If they are simply elevated, they can first be intervened by: controlling fat intake, eating less sweets, and exercising more. If you still do not meet the standard, you can go to the hospital and have your doctor customize a drug treatment plan.
