Inflammation

Interleukin-6 (IL-6)

IL-6 is a key marker for exercise-induced inflammation and recovery. Athletes can use it to monitor training load, detect overtraining, and optimise recovery protocols.

What It Measures

This test measures the concentration of IL-6 cytokine in your blood. Elevated levels may indicate active inflammation, infection, or immune system activation.

Why It Matters

IL-6 is a key mediator of inflammation and immune response. Chronic elevation may be associated with autoimmune diseases, cardiovascular risk, and metabolic conditions. Consult your healthcare provider for interpretation.

When to Test

Testing may be recommended when evaluating chronic inflammatory conditions, autoimmune diseases, or unexplained systemic inflammation.

Symptoms

Low Levels

Low IL-6 levels are normal and indicate a well-regulated immune system. No symptoms are associated with low levels.

High Levels

Elevated IL-6 may be associated with fever, fatigue, chronic pain, autoimmune flares, and increased susceptibility to infections. Persistent elevation warrants investigation.

Lifestyle Tips

Regular moderate exercise, anti-inflammatory foods, quality sleep, and stress management may help regulate IL-6 levels. Avoid overtraining, which can chronically elevate IL-6.

Frequently Asked Questions

Why does exercise increase IL-6?
During exercise, muscles produce IL-6, which has anti-inflammatory effects in this context. This acute rise is different from chronic elevation due to disease.
Is IL-6 always harmful?
No, IL-6 plays important roles in immune defence and recovery. It is chronic elevation that may be associated with health risks.
Can IL-6 predict disease risk?
Elevated IL-6 may be associated with increased risk of certain conditions, but it should be interpreted alongside other markers by your healthcare provider.
