Rheumatoid Arthritis

What is Rheumatoid Arthritis?

Rheumatoid arthritis is a chronic autoimmune disorder that causes inflammation in your joints. Your immune system mistakenly attacks the lining of your joints, called the synovium. This creates painful swelling that can eventually damage cartilage and bone. Unlike wear-and-tear arthritis, rheumatoid arthritis affects the lining of your joints first.

The condition typically affects joints on both sides of your body at the same time. Your hands, wrists, and feet are often affected first. Over time, rheumatoid arthritis can spread to your knees, ankles, elbows, hips, and shoulders. About 1.3 million Americans live with this condition. Women are two to three times more likely to develop it than men.

Rheumatoid arthritis is not just a joint disease. It can also affect your eyes, lungs, heart, blood vessels, and skin. Early detection and treatment can help prevent joint damage and reduce symptoms. Blood testing plays a key role in identifying inflammation and antibodies linked to this condition.

Symptoms

Joint pain, tenderness, and stiffness lasting more than 30 minutes in the morning
Swelling in multiple joints, often affecting both sides of the body
Warm, red joints that feel tender to touch
Fatigue and low energy that interferes with daily activities
Low-grade fever that comes and goes
Loss of appetite and unintended weight loss
Joint deformity or reduced range of motion over time
Firm lumps under the skin near affected joints, called rheumatoid nodules
Dry eyes and mouth
Numbness or tingling in hands and feet

Some people experience mild symptoms that come and go in episodes called flares. Others have continuous symptoms that gradually worsen. Early rheumatoid arthritis may cause subtle symptoms that are easy to miss or attribute to other causes.

Causes and risk factors

Rheumatoid arthritis develops when your immune system attacks healthy joint tissue. Researchers do not know exactly what triggers this autoimmune response. Genetics play a role, as the condition often runs in families. Certain gene variations, particularly those related to the HLA system, increase your risk. However, having these genes does not guarantee you will develop the condition.

Environmental factors also contribute to rheumatoid arthritis risk. Smoking is the strongest lifestyle risk factor and can make the condition more severe. Obesity increases inflammation in your body and raises your risk. Exposure to certain bacteria and viruses may trigger the condition in people who are genetically susceptible. Hormonal changes may explain why women are more likely to develop rheumatoid arthritis. The condition often begins between ages 40 and 60, but it can start at any age.

How it's diagnosed

Doctors diagnose rheumatoid arthritis using a combination of physical examination, blood tests, and imaging studies. During an exam, your doctor checks for joint swelling, redness, warmth, and reflexes. Blood tests help identify inflammation and specific antibodies associated with the condition. No single test can confirm rheumatoid arthritis, but testing helps build a clear picture of what is happening in your body.

Rite Aid offers comprehensive blood testing that measures key inflammation markers and antibodies. Tests like C-Reactive Protein and Sed Rate show how much inflammation is present in your body. Rheumatoid Factor and Cyclic Citrullinated Peptide Antibody help identify the autoimmune activity specific to rheumatoid arthritis. Additional tests like ANA Screen and complement components help rule out other conditions. Regular testing allows you and your doctor to monitor disease activity and adjust treatment as needed.

Treatment options

Disease-modifying antirheumatic drugs that slow the progression of joint damage
Nonsteroidal anti-inflammatory drugs to reduce pain and inflammation
Corticosteroids to quickly reduce inflammation during flares
Biologic agents that target specific parts of the immune system
Regular low-impact exercise like swimming, walking, or tai chi to maintain joint flexibility
Physical therapy to strengthen muscles around affected joints
Anti-inflammatory diet rich in omega-3 fatty acids, vegetables, and whole grains
Weight management to reduce stress on joints and lower inflammation
Stress reduction techniques like meditation or deep breathing
Adequate sleep of 7 to 9 hours per night to support immune function
Smoking cessation, which can improve treatment effectiveness
Hot and cold therapy to manage pain and stiffness

Frequently asked questions

Rheumatoid arthritis is an autoimmune disease where your immune system attacks joint tissue. Osteoarthritis is caused by wear and tear on joints over time. Rheumatoid arthritis typically affects joints on both sides of your body and can cause systemic symptoms like fatigue. Osteoarthritis usually develops gradually in weight-bearing joints and does not involve the immune system.

Blood tests cannot diagnose rheumatoid arthritis alone, but they provide important evidence. Tests like Rheumatoid Factor and Cyclic Citrullinated Peptide Antibody identify antibodies commonly seen in this condition. Inflammation markers like C-Reactive Protein and Sed Rate show disease activity. Your doctor combines blood test results with physical examination and imaging to make a diagnosis.

Testing frequency depends on your disease activity and treatment plan. Many people get blood tests every 3 to 6 months to monitor inflammation and check for medication side effects. Your doctor may recommend more frequent testing when starting new medications or during flares. Regular monitoring helps ensure your treatment is working and catches problems early.

Rheumatoid arthritis has a genetic component, but it is not directly inherited. Having a family member with the condition increases your risk by about 2 to 3 times. Certain gene variations increase susceptibility, but most people with these genes never develop the condition. Environmental factors like smoking also play a significant role in whether you develop rheumatoid arthritis.

Many people find that certain foods trigger inflammation and worsen symptoms. Common triggers include processed foods, refined sugars, red meat, and fried foods. Some people are sensitive to gluten or nightshade vegetables like tomatoes and peppers. An anti-inflammatory diet rich in fish, vegetables, fruits, and whole grains may help reduce symptoms and disease activity.

Yes, with early diagnosis and proper treatment, many people achieve remission. Remission means you have little to no disease activity and minimal symptoms. About 20 to 40 percent of people reach remission with current treatments. However, rheumatoid arthritis is a chronic condition, and remission requires ongoing treatment and monitoring to maintain.

Regular exercise helps reduce pain, improve joint function, and increase overall health. Low-impact activities like swimming, cycling, and walking are especially beneficial. Exercise strengthens muscles around joints, which provides better support and stability. Rest during flares, but stay active during periods of low disease activity to maintain mobility and prevent stiffness.

A positive Rheumatoid Factor test means antibodies called rheumatoid factor are present in your blood. About 70 to 80 percent of people with rheumatoid arthritis test positive for this antibody. However, some healthy people also test positive, and some people with rheumatoid arthritis test negative. Your doctor uses this test along with other findings to make a diagnosis.

Stress does not cause rheumatoid arthritis, but it can trigger flares and worsen symptoms. Stress increases inflammation in your body and may affect immune system function. Managing stress through meditation, yoga, therapy, or other relaxation techniques can help reduce disease activity. Getting adequate sleep and maintaining social connections also help reduce stress and improve outcomes.

The Cyclic Citrullinated Peptide antibody test detects specific antibodies found in rheumatoid arthritis. CCP antibodies are more specific to rheumatoid arthritis than Rheumatoid Factor. A positive CCP test often appears early in the disease and suggests a more aggressive form. This test helps doctors diagnose rheumatoid arthritis earlier and predict which patients may benefit from more intensive treatment.
