1. What strategies can be used to lower triglyceride levels?
For many people, high triglycerides are caused by another disorder such as diabetes, obesity, renal failure, or alcoholism. With these conditions, the strategy is to treat the primary cause. When high triglycerides are not caused by another disorder, they are often seen together with high cholesterol, and treatment is directed toward lowering both cholesterol and triglycerides. Lifestyle changes such as a healthy diet and increased exercise are usually the primary strategy for lowering levels. If these fail, lipid-lowering medications such as statins are generally recommended. For more on this, visit the American Heart Association’s webpage on Diet and Lifestyle Recommendations.
2. Can I monitor triglyceride levels at home?
A few products are available to test lipid levels, including triglycerides, at home. There are two types of home testing: those where you collect the sample at home and then mail it away to a laboratory for testing and those where you conduct the test yourself at home (self-monitoring). The American Heart Association hasn’t taken a position on the use of home testing devices for measuring lipid levels. Before making the decision to use one of these products, you may want to review the article about home testing on this site: With Home Testing, Consumers Take Charge of Their Health.
3. What is VLDL and how does it relate to triglyceride?
Very Low Density Lipoprotein (VLDL) is one of three major lipoprotein particles. The other two are high density lipoprotein (HDL) and low density lipoprotein (LDL). Each one of these particles contains a mixture of cholesterol, protein, and triglyceride, but in varying amounts unique to each type of particle. LDL contains the highest amount of cholesterol. HDL contains the highest amount of protein. VLDL contains the highest amount of triglyceride. Since VLDL contains most of the circulating triglyceride and since the compositions of the different particles are relatively constant, it is possible to estimate the amount of VLDL-cholesterol by dividing the triglyceride value (in mg/dL) by 5. At present, there is no simple, direct way of measuring VLDL-cholesterol, so the estimate calculated from triglyceride is used in most settings. This calculation is not valid when the triglyceride is greater than 400 mg/dL. Increased levels of VLDL-cholesterol have been found to be associated with increased risk of heart disease and stroke.
