Triglyceride 1.98mmol/L is high, but is mildly elevated, not very serious; if combined with other diseases such as cardiovascular disease, diabetes, hypertension and so on, the degree of severity is relatively higher. The normal value of triglyceride is generally less than <1.7mmol/L, 1.7~2.2mmol/L is borderline elevated, 2.3~5.5mmol/L is elevated, and ≥5.6mmol/L is severely elevated. So triglyceride 1.98mmol/L exceeds the normal value and is mildly elevated. In normal life, we should pay attention to eat more vegetables, eat less animal fat, animal offal, egg yolk, fried food and other high-fat food, obese people should pay attention to weight control, and take lipid-lowering drugs treatment if necessary. Elevated triglycerides, if combined with cardiovascular and cerebrovascular diseases, diabetes mellitus, hypertension, etc., the degree of severity is relatively higher. It is important to aggressively control lipid levels to prevent disease progression. Patients with elevated triglyceride levels should be treated aggressively under the supervision of a physician.
