What is Triglycerides?
Triglycerides are the main form of fat stored in the body. After eating, unused calories are converted into triglycerides and stored in fat cells for later energy use.
Triglycerides should be measured after an 8–12 hour fast for accuracy. Non-fasting triglycerides are increasingly used in cardiovascular risk algorithms, but fasting values remain the standard for diagnosis.
Why might Triglycerides be low?
Very low triglycerides are generally not a concern and may simply reflect a low-fat diet or high physical activity.
This information is educational. A single out-of-range result is rarely the whole picture — a healthcare professional can interpret your numbers alongside your overall health and history.
Context questions that matter
- →Was this result slightly or clearly outside the reference range?
- →Were related markers also high or low?
- →Is this new compared with previous tests?
- →Could recent illness, exercise, fasting, alcohol, supplements, or medication affect it?
- →Do you have symptoms that should be discussed with a clinician?
Markers often reviewed together with Triglycerides
Clinicians rarely look at one number in isolation. These markers usually accompany Triglycerides on a lipid panel panel and help put the result in context.
Lifestyle considerations
- •Reducing refined sugars and starches is the most effective dietary change to lower triglycerides
- •Limiting alcohol consumption can produce rapid reductions in triglyceride levels
- •Regular exercise significantly lowers triglycerides
Questions to ask your doctor
- →What does this mean together with LDL, HDL, triglycerides, non-HDL cholesterol and ApoB if available?
- →Should this be repeated fasting, or interpreted with my overall cardiovascular risk?
- →Are family history, blood pressure, glucose or other risk factors important here?
Don't guess from one flagged result.
Start with the most relevant panel and see how your markers fit together in plain English.
Frequently asked questions
What does low Triglycerides mean?
+
Very low triglycerides are generally not a concern and may simply reflect a low-fat diet or high physical activity.
What is Triglycerides?
+
Triglycerides are the main form of fat stored in the body. After eating, unused calories are converted into triglycerides and stored in fat cells for later energy use.
Is one cholesterol marker enough to understand cardiovascular risk?
+
Usually no. LDL, HDL, triglycerides, non-HDL cholesterol and ApoB (when available) are read together with age, blood pressure, glucose, smoking status and family history. A single marker rarely tells the whole story.
Should lipid results be fasting?
+
Many lipid markers can be interpreted non-fasting, but triglycerides and some follow-up decisions may depend on fasting status. Check the lab's note on the report, or ask your doctor whether your specific test was meant to be fasting.
What supports healthy Triglycerides levels?
+
Reducing refined sugars and starches is the most effective dietary change to lower triglycerides. Limiting alcohol consumption can produce rapid reductions in triglyceride levels. Regular exercise significantly lowers triglycerides
