Triglycerides
LOINC 2571-8 · mg/dL
What it is
Triglycerides are the most common type of fat in the body, carried in the blood and used for energy. Levels rise after eating and with excess calories.
Why it matters
High triglycerides are linked to cardiovascular risk and metabolic conditions, and very high levels can also affect the pancreas.
What high values can mean
A higher value is linked to excess calories, refined carbs, alcohol, inactivity or metabolic conditions, and to greater cardiovascular risk.
What low values can mean
A lower value is generally favourable.
How to improve it
Cutting sugar, refined carbs and alcohol, losing excess weight and exercising regularly are the most effective ways to lower triglycerides.
Food & lifestyle
Limit sugary drinks, sweets, white bread and alcohol; favour vegetables, whole grains, fish and unsaturated fats.
Preparing for the testFasting required
Part of a lipid panel; fasting (9–12 h) is usually requested for an accurate triglyceride result — follow your lab.
When to talk to a doctor
Discuss high triglycerides with a doctor, especially if very high or alongside other metabolic risk factors.
