elevated triglycerides and heart disease

Understanding Triglycerides

Triglycerides are a type of fat (lipid) found in your blood. After you eat, your body converts unused calories into triglycerides and stores them in fat cells. Between meals, hormones release those triglycerides for energy. While they play an important role in your body, having too many triglycerides can be a warning sign for your heart health.

Triglyceride Levels Explained

A simple blood test called a lipid panel measures your triglyceride levels. Testing is typically done after fasting for 9–12 hours.

  • Normal: Less than 150 mg/dL
  • Borderline High: 150–199 mg/dL
  • High: 200–499 mg/dL
  • Very High: 500 mg/dL or higher

Keeping your triglycerides within a healthy range is an important part of overall heart health.

What Causes High Triglycerides?

Several factors can push triglycerides into an unhealthy range. Diet is the most immediate — excess sugar, refined carbohydrates, and alcohol are major contributors. Beyond diet, certain medications and underlying conditions also play a role. Causes of high triglycerides include:

  • Diet high in sugars and refined carbohydrates
  • Excess calorie intake
  • Being overweight or inactive
  • Smoking
  • Excessive alcohol use
  • Certain medications ((including corticosteroids, beta-blockers, and some diuretics)
  • Underlying medical conditions (Type 2 diabetes and insulin resistance, hypothyroidism, and kidney disease)
  • Genetics (familial hypertriglyceridemia is an inherited condition that causes elevated levels regardless of lifestyle)

Often, high triglycerides occur alongside other cholesterol abnormalities.

How To Lower Triglycerides

Improving triglyceride levels typically involves simple, sustainable lifestyle changes. Even modest improvements can produce meaningful reductions within weeks.

  • Eat a heart-healthy diet rich in fruits, vegetables, and whole grains
  • Reduce sugar and processed food intake
  • Maintain a healthy weight
  • Exercise regularly
  • Limit alcohol consumption

In some cases, medication may be recommended by your provider.

When To See A Cardiologist

If you have high triglycerides, especially alongside other risk factors like diabetes, high cholesterol, or a family history of heart disease, it’s important to seek expert guidance. A cardiologist can evaluate your overall risk and develop a personalized plan to help protect your heart.

Routine blood testing is the first step. At CardioNow, triglyceride levels are measured as part of comprehensive cholesterol testing, with results reviewed by a physician to ensure timely, accurate care.
