Inflammatory Diseases
What is Inflammatory Diseases?
Inflammatory diseases are conditions where your immune system attacks healthy tissues in your body. This causes long-term inflammation that can damage organs, joints, and other body systems. Common inflammatory diseases include rheumatoid arthritis, inflammatory bowel disease, lupus, and psoriasis.
Inflammation is normally a helpful response to injury or infection. Your body sends immune cells to fight threats and heal damage. But in inflammatory diseases, this response never shuts off. Your immune system mistakes healthy cells for enemies and attacks them continuously.
Chronic inflammation can affect almost any part of your body. It may target your joints, digestive tract, skin, blood vessels, or multiple systems at once. These conditions are often called autoimmune diseases because your immune system is working against itself. Early detection through blood testing can help you manage these conditions before serious damage occurs.
Symptoms
- Joint pain, stiffness, or swelling that lasts for weeks or months
- Persistent fatigue that does not improve with rest
- Low-grade fever that comes and goes
- Skin rashes or changes in skin appearance
- Digestive problems like diarrhea, cramping, or blood in stool
- Unexplained weight loss or loss of appetite
- Muscle aches and weakness
- Dry eyes or mouth
- Chest pain or difficulty breathing
- Swollen lymph nodes
Some people have mild symptoms for years before getting diagnosed. Others develop severe symptoms quickly. Many inflammatory diseases go through periods of flare-ups and remission, where symptoms come and go.

Causes and risk factors
Inflammatory diseases happen when your immune system malfunctions and attacks healthy tissue. Doctors do not fully understand why this occurs, but genetics play a major role. If family members have autoimmune conditions, your risk increases. Environmental triggers like infections, toxins, or stress may activate these genes and start the disease process.
Lifestyle factors can influence inflammation levels in your body. A diet high in processed foods, sugar, and unhealthy fats can worsen inflammation. Smoking, excessive alcohol use, and chronic stress also contribute. Low levels of omega-3 fatty acids like EPA, DPA, and DHA may increase your risk of inflammatory diseases because these nutrients have natural anti-inflammatory properties. Lack of sleep, sedentary behavior, and excess body weight create more inflammation throughout your system.
How it's diagnosed
Doctors diagnose inflammatory diseases through a combination of physical exams, medical history, imaging tests, and blood work. Blood tests are essential for detecting inflammation markers and identifying specific autoimmune antibodies. Rite Aid offers add-on testing to measure key biomarkers related to inflammation.
Albumin levels can reveal chronic inflammation, as ongoing immune activity lowers albumin production in your liver. The OmegaCheck test measures omega-3 fatty acids like EPA, DPA, and DHA in your blood. Low levels of these anti-inflammatory fats may indicate higher risk for conditions like rheumatoid arthritis. Your doctor may order additional tests to confirm a specific diagnosis, including imaging studies or biopsies of affected tissues.
Treatment options
- Anti-inflammatory medications like NSAIDs to reduce pain and swelling
- Disease-modifying antirheumatic drugs that slow immune system attacks
- Biologic medications that target specific parts of the immune response
- Corticosteroids for short-term control of severe flare-ups
- Increase omega-3 fatty acids through fatty fish, fish oil supplements, or algae-based sources
- Follow an anti-inflammatory diet rich in vegetables, fruits, whole grains, and healthy fats
- Eliminate or reduce processed foods, refined sugar, and trans fats
- Exercise regularly with low-impact activities like swimming, walking, or yoga
- Practice stress management through meditation, deep breathing, or counseling
- Get 7 to 9 hours of quality sleep each night
- Maintain a healthy weight to reduce strain on joints and lower inflammation
- Quit smoking and limit alcohol consumption

Frequently asked questions
The most common inflammatory diseases include rheumatoid arthritis, which affects joints, and inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis. Lupus, psoriasis, psoriatic arthritis, and ankylosing spondylitis are also prevalent. Many people live with these conditions for decades with proper treatment and lifestyle changes.
Yes, blood tests are essential for detecting and monitoring inflammatory diseases. Tests measure inflammation markers like albumin levels and omega-3 fatty acids. Your doctor may also order tests for specific antibodies, C-reactive protein, or erythrocyte sedimentation rate. Rite Aid offers add-on testing to measure albumin and omega-3 levels related to inflammation.
Omega-3 fatty acids like EPA, DPA, and DHA have natural anti-inflammatory properties that can reduce immune system overactivity. These nutrients help balance your body's inflammatory response and may decrease joint pain and stiffness. You can increase omega-3 levels by eating fatty fish like salmon, taking fish oil supplements, or using algae-based omega-3 products.
Most inflammatory diseases are chronic conditions that cannot be cured, but they can be managed effectively. Treatment focuses on reducing inflammation, preventing tissue damage, and controlling symptoms. Many people achieve remission, where symptoms disappear for months or years. Early diagnosis and consistent treatment lead to the best long-term outcomes.
Avoid processed foods, refined sugars, white bread, and pastries that trigger inflammation. Limit red meat, fried foods, and products with trans fats or partially hydrogenated oils. Many people also reduce dairy, gluten, or nightshade vegetables if these cause personal flare-ups. Focus instead on whole foods like vegetables, fruits, fish, nuts, and olive oil.
Yes, chronic stress can trigger flare-ups and worsen symptoms of inflammatory diseases. Stress hormones like cortisol affect your immune system and increase inflammation throughout your body. Managing stress through meditation, exercise, adequate sleep, and social support can help reduce disease activity. Many people notice fewer symptoms when they address emotional and mental health.
Most doctors recommend testing every 3 to 6 months when your disease is active or treatment is changing. Once you achieve stable remission, you may only need testing once or twice per year. Regular monitoring helps track inflammation levels, medication side effects, and overall disease progression. Your doctor will create a testing schedule based on your specific condition and treatment plan.
Yes, regular exercise reduces inflammation and helps manage many inflammatory disease symptoms. Low-impact activities like swimming, walking, cycling, and yoga are especially helpful for joint conditions. Exercise also improves mood, energy levels, and sleep quality. Start slowly and listen to your body, resting during flare-ups when needed.
Your gut contains 70% of your immune system, so digestive health strongly affects inflammation throughout your body. An imbalanced gut microbiome can trigger or worsen autoimmune responses. Eating probiotic foods like yogurt, fermented vegetables, and kefir may help. Avoiding foods that damage gut lining, like alcohol and NSAIDs taken long-term, also supports immune balance.
Early detection allows treatment to begin before permanent damage occurs to joints, organs, or other tissues. Many inflammatory diseases cause irreversible changes if left untreated for years. Starting treatment early can prevent disability, reduce pain, and improve quality of life. Blood testing helps identify inflammation before symptoms become severe or complications develop.
