Does elevated triglyceride level require treatment? A tiered management plan for dyslipidemia.

Elevated triglycerides are very common, but do they need treatment?

Triglycerides are a common component of blood lipid tests, and many young people find they have elevated triglycerides. In this lecture, Dr. Zhou will discuss what to do about elevated triglycerides.

Many hospital lab reports list the upper limit of normal triglyceride levels as around 1.7 mmol/L. However, the clinical standard for diagnosing hypertriglyceridemia is triglycerides ≥ 2.3 mmol/L. Levels of 1.7 mmol/L ≤ triglycerides < 2.3 mmol/L can be called "high triglycerides," and levels > 5.6 mmol/L are called "severely elevated triglycerides."

The Dangers of Elevated Triglycerides

Although triglycerides have a less significant impact on cardiovascular disease than cholesterol, they still increase the risk of coronary heart disease. Furthermore, severely elevated triglycerides primarily damage the pancreas, potentially leading to severe necrotizing pancreatitis. Therefore, this should be taken seriously.

Causes of Elevated Triglycerides: Well-established causes of elevated triglycerides include excessive alcohol consumption, obesity, diabetes, medication effects, and hypothyroidism. Triglycerides are significantly affected by diet; drinking alcohol one day can result in very high triglyceride levels the next. Therefore, it's crucial to control your diet the night before a blood lipid test.

Treatment for High Triglycerides: For elevated triglycerides (1.7–2.3 mmol/L), lifestyle modifications should be prioritized, including quitting smoking, limiting alcohol consumption, weight control, exercise, and a low-salt, low-fat diet.

For mild to moderately elevated triglycerides (2.3–5.6 mmol/L), statins can be taken in addition to lifestyle modifications. While statins primarily lower cholesterol, they can also lower triglycerides and offer cardioprotection.

For severely elevated triglycerides (>5.6 mmol/L), fibrates should be used to quickly lower triglycerides to a safe level.

It is important to note that statins are sometimes used in combination with fibrates. Neither should be taken in excessive doses. Generally, fibrates are taken in the morning and statins are taken in the evening to avoid peak blood drug concentrations. Liver function and creatine kinase levels should be monitored regularly.
