What does chronic inflammation actually mean and how do I know if I have it?

Chronic low-grade inflammation is not the same as the redness and swelling you see after an injury. It is a persistent, low-level immune activation that often produces no obvious symptoms on its own — but silently drives damage across multiple body systems over time.

The downstream effects of chronic inflammation include:

• Fatigue and low energy (inflammation is metabolically expensive)
• Brain fog and cognitive slowing (inflammatory cytokines cross the blood-brain barrier)
• Weight gain and difficulty losing weight (inflammation drives insulin resistance)
• Skin issues including acne, eczema, and premature aging
• Joint pain and stiffness
• Mood changes, anxiety, and depression
• Accelerated cardiovascular risk

Chronic inflammation is measurable through specific lab markers — but none of these appear on a standard annual physical. The most clinically useful markers include:

• High-sensitivity CRP (hsCRP) — the most widely used inflammatory marker; optimal is below 1.0 mg/L
• Homocysteine — elevated levels indicate both inflammatory and cardiovascular risk
• Ferritin — an acute-phase reactant that rises with inflammation independent of iron status
• Fasting insulin — insulin resistance is both a driver and a consequence of chronic inflammation

The drivers of chronic inflammation include gut permeability, blood sugar dysregulation, hormonal imbalance, environmental exposures, chronic stress, and poor sleep. Identifying your specific drivers — not just measuring the inflammation — is the first step to resolving it.
