Primary Causes & Action Plans

hs-CRP

The gold standard marker for systemic inflammation
High-sensitivity C-reactive protein is an acute-phase reactant produced by the liver in response to inflammatory cytokines, primarily IL-6. It is the most widely validated and commonly used blood marker for systemic inflammation, with applications in cardiovascular risk assessment and monitoring inflammatory conditions.

Target < 1.0 mg/L (optimal)
Suggested Action Plan

If hs-CRP is elevated, investigate root causes: visceral fat, poor diet, chronic infections, gum disease, sleep apnea, chronic stress, autoimmune conditions, or environmental toxins. Adopt anti-inflammatory strategies: Mediterranean diet, regular exercise, omega-3 fatty acids, adequate sleep, and stress management.

ESR

Erythrocyte sedimentation rate measures blood viscosity from inflammation
Erythrocyte Sedimentation Rate (ESR) measures how quickly red blood cells settle to the bottom of a test tube over one hour. During inflammation, proteins like fibrinogen and immunoglobulins increase in the blood, causing red blood cells to clump together and settle faster. ESR is a nonspecific but sensitive marker of inflammation.

Target < 10 mm/hr (optimal)
Suggested Action Plan

If ESR is elevated alongside hs-CRP, this confirms systemic inflammation. Investigate autoimmune conditions, chronic infections, and other inflammatory sources. If ESR is elevated but hs-CRP is normal, consider conditions affecting plasma proteins (multiple myeloma, chronic kidney disease). Retest after addressing identified causes.

Ferritin

Iron storage protein that rises with inflammation
Ferritin is the primary iron storage protein in the body. While low ferritin reliably indicates iron deficiency, elevated ferritin can indicate iron overload, chronic inflammation, liver disease, or metabolic syndrome. In the context of inflammation, ferritin acts as an acute-phase reactant, rising independently of iron status.

Target 50 - 150 ng/mL (optimal)
Suggested Action Plan

If ferritin is low (< 30 ng/mL), supplement iron and investigate causes of depletion. If ferritin is elevated (> 200 ng/mL), distinguish between iron overload and inflammation by testing iron saturation, hs-CRP, and liver enzymes. Elevated ferritin with high hs-CRP suggests inflammatory elevation. Elevated ferritin with high iron saturation suggests true iron overload (test for hereditary hemochromatosis).

Fibrinogen

Clotting protein elevated by chronic inflammation
Fibrinogen is a glycoprotein produced by the liver that plays a central role in blood clotting. It is converted to fibrin during the coagulation cascade. As an acute-phase reactant, fibrinogen levels rise during inflammation, increasing blood viscosity and clotting tendency. Chronically elevated fibrinogen is an independent risk factor for cardiovascular disease and stroke.

Target < 300 mg/dL (optimal)
Suggested Action Plan

If fibrinogen is elevated, prioritize anti-inflammatory interventions. Omega-3 fatty acids, regular exercise, and nattokinase (a fibrinolytic enzyme) can help reduce fibrinogen levels. Address the underlying inflammatory cause.

IL-6

The master cytokine driving inflammatory cascades
Interleukin-6 (IL-6) is a pro-inflammatory cytokine produced by immune cells, fat tissue, and stressed tissues. It is the primary signal that stimulates the liver to produce CRP and fibrinogen. IL-6 is elevated in obesity, chronic infections, autoimmune diseases, and metabolic syndrome. It is an upstream driver of the entire acute-phase inflammatory response.
Read detailed analysis
Target < 1.8 pg/mL (optimal)
Suggested Action Plan

If IL-6 is elevated, it indicates an active inflammatory process. Investigate visceral adiposity (belly fat is a major source of IL-6), chronic infections, autoimmune activity, and environmental triggers. Anti-inflammatory interventions include weight loss, Mediterranean diet, regular exercise, adequate sleep, omega-3 supplementation, and stress reduction.

Getting Started

1
Identify Inflammation Sources

Test hs-CRP, ESR, ferritin, fibrinogen, and IL-6 to confirm and quantify inflammation. Then investigate common sources: visceral fat, poor diet, chronic infections, gum disease, sleep apnea, environmental toxins, and autoimmune conditions.

2
Adopt an Anti-Inflammatory Diet

Emphasize vegetables, fruits, fatty fish, olive oil, nuts, and seeds. Eliminate processed foods, refined seed oils, added sugars, and excess alcohol. A Mediterranean or whole-foods diet has been shown to significantly reduce inflammatory markers.

3
Test Regularly

Retest inflammatory markers every 3-6 months to track progress. Improving trends confirm that your interventions are working. Persistent elevation despite lifestyle changes may warrant deeper investigation.

4
Reduce Triggers

Prioritize 7-9 hours of quality sleep, manage chronic stress, exercise consistently but avoid overtraining, maintain a healthy body composition, address dental health, and minimize exposure to environmental pollutants and toxins.

Why I built this guide.

"Chronic inflammation is the common thread linking most modern diseases. Testing is the first step toward identifying and resolving the root causes."
