Triglycerides 4.88mmol/L is more serious, triglyceride level in the body between 2.26-5.63mmol/L is high, greater than 5.64mmol/L should be treated immediately with drugs. Under normal circumstances, there is a dynamic balance of triglycerides in the human blood, and the triglycerides in the blood are mainly of exogenous and endogenous origin. Endogenous triglycerides are synthesized by the liver and fatty tissues, and this part of triglycerides has the role of energy supply and storage, but also can play a role in protecting the internal organs. Exogenous triglycerides are food intake, where the fat in food is absorbed by the intestinal mucosa through the action of lipase and bile acids, and then triglycerides are synthesized by cells. Most of the triglycerides in the body are derived from this, with endogenous sources accounting for only a small percentage. Triglycerides can store energy for the body and are non-toxic and harmless in themselves. If triglycerides are high, the walls of blood vessels become weak, making them thicker and thicker, and blood flow becomes slower and slower as a result. At this point the load on the heart increases and blood flow begins to be impeded or even interrupted. Triglycerides combine with blood cells to form blood clots, which are called “heart attacks” in the heart and “brain attacks” in the brain.
