Triglycerides are a key marker on a cholesterol test and an important indicator of metabolic and cardiovascular health. If your triglyceride levels are elevated, it can signal insulin resistance, inflammation, or increased heart disease risk. The good news is that triglycerides often respond quickly to lifestyle changes once the underlying causes are addressed.
This guide explains what triglycerides are, what high levels mean, and how to lower them safely and effectively.

What are triglycerides?
Triglycerides are a type of fat found in the blood. After you eat, your body converts excess calories — especially from carbohydrates and sugar — into triglycerides for storage. These fats are later used for energy between meals.
Triglycerides are measured as part of a standard cholesterol test and are included in a lipid panel along with LDL, HDL, and total cholesterol:

While triglycerides are essential for energy balance, chronically elevated levels can increase the risk of cardiovascular disease and metabolic disorders.
Triglyceride levels: what is considered normal?
| Triglyceride Level | Interpretation |
|---|---|
| Under 100 mg/dL | Optimal |
| 100–149 | Borderline |
| 150–199 | Elevated |
| 200–499 | High |
| 500+ | Very high |
Levels above 150 mg/dL are generally considered elevated and may increase cardiovascular risk, especially when combined with low HDL or high LDL.
What causes high triglycerides?
High triglycerides are often linked to metabolic health rather than dietary fat intake alone.
Common causes include:
- High sugar or refined carbohydrate intake
- Insulin resistance
- Weight gain or obesity
- Alcohol consumption
- Physical inactivity
- Poor sleep
- Chronic stress
- Diabetes or prediabetes
- Hypothyroidism
- Certain medications
- Genetic factors
Many people with elevated triglycerides also have low HDL and signs of metabolic syndrome.
Why high triglycerides matter
Elevated triglycerides are associated with:
- Increased cardiovascular risk
- Insulin resistance
- Fatty liver disease
- Inflammation
- Higher risk of type 2 diabetes
Very high triglycerides (typically above 500 mg/dL) can also increase the risk of pancreatitis, a serious condition involving inflammation of the pancreas.
Triglycerides should always be interpreted alongside other markers in a lipid panel:

How triglycerides fit into the bigger picture
Triglycerides rarely act alone. Patterns across the lipid panel provide important clues.
High triglycerides + low HDL
Often associated with insulin resistance or metabolic syndrome.
High triglycerides + high LDL
May increase cardiovascular risk and signal metabolic imbalance.
High triglycerides + normal LDL
Can still indicate metabolic dysfunction even if LDL appears acceptable.
Looking at triglycerides in context helps guide the right interventions.
How to lower triglycerides
Triglycerides often respond quickly to targeted lifestyle changes.
Reduce sugar and refined carbohydrates
Excess sugar is one of the strongest drivers of elevated triglycerides. Reducing added sugar and refined grains can significantly lower levels.
Improve insulin sensitivity
Regular exercise and balanced meals can help regulate blood sugar and reduce triglyceride production.
Increase physical activity
Aerobic exercise and resistance training can lower triglycerides and improve overall lipid balance.
Limit alcohol
Alcohol can significantly raise triglycerides in some individuals, even at moderate intake levels.
Focus on whole foods
A diet rich in fiber, vegetables, healthy fats, and protein can help stabilize triglycerides and improve metabolic health.
Omega-3 fatty acids
Omega-3s from fatty fish or supplements may help lower triglycerides in some individuals.
When medication may be considered
If triglycerides remain significantly elevated despite lifestyle changes, clinicians may consider medication or targeted therapies. Treatment decisions depend on overall cardiovascular risk and other lipid markers.
When to recheck triglycerides
Repeat testing is often recommended:
- After dietary or lifestyle changes
- Every 3–12 months if elevated
- When monitoring treatment
- As part of routine preventive care
Tracking trends over time provides more insight than a single measurement.
Common questions
Are triglycerides 200 high?
Triglycerides around 200 mg/dL are considered high and may increase cardiovascular risk. Lifestyle changes can often improve levels.
Are triglycerides 150 bad?
Levels around 150 mg/dL are borderline elevated and may signal metabolic imbalance.
Can triglycerides be lowered quickly?
Yes. Reducing sugar intake, increasing physical activity, and improving metabolic health can lower triglycerides within weeks.
Do triglycerides increase heart disease risk?
Elevated triglycerides are associated with increased cardiovascular risk, especially when combined with low HDL or high LDL.
The bottom line
High triglycerides are common and often reflect underlying metabolic health. The good news is that they are highly responsive to lifestyle changes, particularly improvements in diet, exercise, and insulin sensitivity.
