Inflammation
What is Inflammation?
Inflammation is your body's natural defense system against injury, infection, and harmful substances. When your immune system detects a threat, it sends white blood cells and chemicals to protect the affected area. This process causes redness, warmth, swelling, and sometimes pain. Acute inflammation is helpful and usually resolves within days or weeks.
Chronic inflammation is different. It happens when your immune system stays activated for months or years, even without an obvious threat. This prolonged response can damage healthy cells, tissues, and organs. Over time, chronic inflammation contributes to serious health problems including heart disease, diabetes, arthritis, and certain cancers.
Many lifestyle factors drive chronic inflammation. Poor diet, lack of exercise, stress, inadequate sleep, and excess body fat all trigger ongoing immune activation. The good news is that inflammation levels can be measured through blood tests and often improved through targeted lifestyle changes.
Symptoms
- Persistent fatigue that does not improve with rest
- Joint pain, stiffness, or swelling
- Digestive issues including bloating, gas, or irregular bowel movements
- Frequent infections or slow wound healing
- Skin problems such as rashes, acne, or eczema
- Brain fog, difficulty concentrating, or memory problems
- Unexplained weight gain or difficulty losing weight
- Muscle aches and body pain
- Mood changes including depression or anxiety
- Allergies or increased sensitivity to foods
Many people with chronic inflammation have no obvious symptoms in the early stages. The condition often develops silently over years, making regular blood testing important for early detection.

Causes and risk factors
Chronic inflammation develops when your immune system remains in a constant state of alert. Diet plays a major role, especially consumption of processed foods, refined sugars, trans fats, and excess omega-6 fatty acids. Being overweight or obese triggers inflammation because fat tissue releases inflammatory chemicals. Lack of physical activity, chronic stress, and poor sleep quality all keep your immune system activated. Smoking, excess alcohol consumption, and environmental toxins also contribute to ongoing inflammation.
Some people have higher risk due to age, as inflammation tends to increase after age 50. Autoimmune conditions such as rheumatoid arthritis or lupus cause persistent inflammation. Chronic infections, gum disease, and ongoing exposure to allergens can trigger long-term immune activation. Genetics play a role too, with some people naturally producing more inflammatory chemicals. Identifying and addressing your specific triggers is key to reducing inflammation.
How it's diagnosed
Inflammation is diagnosed through blood tests that measure specific inflammatory markers in your body. C-Reactive Protein, or CRP, is one of the most reliable indicators. Your liver produces CRP in response to inflammation anywhere in your body. Elevated CRP levels suggest active inflammation, though they do not pinpoint the exact location or cause. Arachidonic Acid levels also provide valuable information, as high amounts can fuel inflammatory processes throughout your body.
Rite Aid offers inflammation testing as an add-on to our preventive health panel. You can get tested at over 2,000 Quest Diagnostics locations nationwide. Regular testing helps you track inflammation levels over time and see how lifestyle changes affect your results. Your doctor may order additional tests based on your symptoms and health history to identify underlying causes.
Treatment options
- Eat an anti-inflammatory diet rich in vegetables, fruits, fatty fish, nuts, seeds, and olive oil
- Reduce or eliminate processed foods, refined sugars, and trans fats from your meals
- Exercise regularly, aiming for at least 150 minutes of moderate activity per week
- Maintain a healthy weight through balanced nutrition and physical activity
- Manage stress with techniques like meditation, deep breathing, or yoga
- Get 7 to 9 hours of quality sleep each night
- Quit smoking and limit alcohol to moderate amounts or less
- Consider omega-3 supplements from fish oil or algae sources
- Take nonsteroidal anti-inflammatory drugs such as ibuprofen for acute symptoms when needed
- Work with a doctor to address underlying conditions like autoimmune disease or chronic infection

Frequently asked questions
Acute inflammation is your body's short-term response to injury or infection, usually lasting days to weeks. It causes visible signs like redness, swelling, and pain. Chronic inflammation persists for months or years, often without obvious symptoms. It damages healthy tissues and contributes to serious diseases over time.
Yes, blood tests can identify elevated inflammatory markers before you notice any symptoms. Tests measuring C-Reactive Protein and Arachidonic Acid reveal inflammation levels in your body. Early detection allows you to make lifestyle changes before chronic inflammation causes lasting damage. Regular testing is especially important if you have risk factors.
Processed foods, refined carbohydrates, and added sugars are major inflammation triggers. Trans fats found in fried foods and baked goods promote inflammatory processes. Red meat and excess omega-6 oils from corn, soybean, and sunflower can increase inflammation when consumed in large amounts. Alcohol and highly processed meats also contribute to chronic inflammation.
Fatty fish like salmon, sardines, and mackerel provide anti-inflammatory omega-3 fatty acids. Colorful vegetables and fruits contain antioxidants that fight inflammation. Nuts, seeds, olive oil, and avocados offer healthy fats that reduce inflammatory markers. Green tea, turmeric, ginger, and dark chocolate also have natural anti-inflammatory properties.
Some people notice improvements in symptoms within 2 to 4 weeks of dietary changes. However, measurable reductions in inflammatory blood markers typically take 6 to 12 weeks. Long-term inflammation that developed over years may require several months of consistent lifestyle modification. Regular blood testing helps track your progress objectively.
No, acute inflammation is actually protective and necessary for healing. When you cut your finger or catch a cold, inflammation helps fight infection and repair tissue. The problem occurs when inflammation becomes chronic and persists without a clear threat. Chronic inflammation damages healthy cells and increases disease risk over time.
Yes, chronic stress triggers your body to release stress hormones and inflammatory chemicals. When stress continues for weeks or months, your immune system stays activated inappropriately. This leads to elevated inflammatory markers in your blood. Managing stress through relaxation techniques, exercise, and adequate sleep helps reduce inflammation levels.
C-Reactive Protein, or CRP, is a substance your liver produces in response to inflammation anywhere in your body. Doctors measure CRP levels to assess overall inflammation and predict heart disease risk. High CRP levels indicate active inflammation that may require investigation and treatment. Tracking CRP over time shows whether your interventions are working.
Some level of inflammation is normal and healthy as part of your immune function. The goal is to keep inflammation within a normal range, not eliminate it entirely. Lifestyle changes can significantly reduce chronic inflammation and bring markers into healthy ranges. However, certain medical conditions may require ongoing management even with optimal lifestyle habits.
Omega-3 fatty acids from fish oil have strong evidence for reducing inflammation safely. Curcumin from turmeric and other plant-based supplements show promise in research studies. Always talk to your doctor before starting supplements, especially if you take medications. Getting anti-inflammatory nutrients from whole foods is generally the safest and most effective approach.
