Triglycerides, Explained in Plain Language

Quick Answer (TL;DR)

Triglycerides are the main type of fat circulating in your blood, largely reflecting recent diet, alcohol and how your body handles sugar.

What It Means

On a lipid panel, under 1.7 mmol/L (150 mg/dL) is generally considered normal. Values above roughly 5.6 mmol/L (500 mg/dL) need prompt attention because of the risk to the pancreas.

Why It Matters for Your Health

High triglycerides usually travel with insulin resistance, excess weight around the middle and low HDL, so the number is a useful early signal of metabolic trouble.

Recommended Biomarker or Metric to Track

Note alcohol intake and whether the sample was fasting alongside each result.

Questions to Ask Your Doctor

Targeted questions based on latest clinical consensus statements.

1What is my triglyceride level, and was the sample fasting?
2Is this high enough to need treatment rather than lifestyle change?
3Could alcohol or a medication be contributing?
4Do I show other signs of insulin resistance?
5How soon should we retest after changes?
