Triglycerides

The main type of fat circulating in your blood — high levels usually signal too many quick carbs, alcohol or insulin resistance.

What it measures

The concentration of triglyceride fat in your blood, ideally measured fasting.

Why it matters

High fasting triglycerides are a marker of poor metabolic health and add to cardiovascular risk. They respond quickly to diet and lifestyle.

Healthy target

< 1.1 mmol/L

How to read your value

A single non-fasting sample can read high after a meal. Persistently high fasting triglycerides point to sugar/refined-carb intake, alcohol or insulin resistance.

What can affect it

• Refined carbohydrates and added sugar
• Alcohol
• Excess body weight and insulin resistance
• Oily fish / omega-3 can lower them
• Physical activity lowers them

Does the target differ by age or sex?

Same target for men and women. Can drift up with age and around menopause; always read fasting.

When to talk to a clinician

Very high triglycerides (well above the target) can risk pancreatitis and need medical attention, not just diet.
