The normal value of triglyceride should be less than 1.7mmol/L, so triglyceride 7.8mmol/L is elevated. Due to different examination methods and reagents, the reference indexes of each hospital are different and need to be analyzed specifically. Patients with triglyceride 7.8mmol/L may be caused by diet, bad habits, heredity and disease factors. For example, excessive fat intake, long-term smoking and drinking may lead to elevated triglycerides; if one or both parents in the family have high triglycerides, the chances of the offspring having high triglycerides may increase. Disease factors such as diabetes, liver disease, kidney disease, etc. may also lead to elevated triglyceride levels, and when elevated triglycerides occur, consult a medical professional for consultation and treatment.
