Rheumatoid arthritis (RA) is an autoimmune disorder that primarily affects the joints, causing inflammation, pain, and stiffness. It occurs when the immune system attacks the body’s own tissues, particularly the synovium, a lining that surrounds the joints. Over time, this can lead to joint damage, deformity, and disability. RA can also affect other parts of the body, such as the eyes, skin, and lungs. It typically develops gradually, with symptoms such as fatigue, fever, and loss of appetite, in addition to joint pain and swelling. There is no cure for RA, but early diagnosis and treatment can help manage symptoms and slow down the progression of the disease.

The diagnosis of rheumatoid arthritis (RA) is typically made by a healthcare provider, such as a rheumatologist. The diagnosis process may include the following:
Medical history: The healthcare provider will ask about your symptoms, when they started, and how they have progressed over time.
Physical examination: The healthcare provider will examine your joints for swelling, tenderness, and range of motion.
Blood tests: Blood tests can help detect certain antibodies and markers that are associated with RA, such as rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, and erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) levels.
Imaging tests: X-rays, ultrasound, or magnetic resonance imaging (MRI) may be used to look for signs of joint damage or inflammation.
Clinical criteria: The American College of Rheumatology (ACR) has established clinical criteria for the diagnosis of RA, which include the presence of certain symptoms, blood test results, and imaging findings.
There is no single test that can definitively diagnose RA, and the diagnosis may take some time to confirm. The healthcare provider may also consider other possible causes of your symptoms, such as other forms of arthritis or autoimmune disorders, before making a final diagnosis.
While there is no cure for rheumatoid arthritis (RA), there are several lifestyle changes that can help manage symptoms and improve quality of life. Some examples include:
Regular exercise: Low-impact activities such as swimming, cycling, and yoga can help improve joint mobility and reduce stiffness. Consult with your healthcare provider before starting an exercise program.
Maintaining a healthy weight: Excess weight can put additional strain on the joints and increase inflammation, so maintaining a healthy weight through diet and exercise can help improve RA symptoms.
Eating a balanced diet: A diet rich in fruits, vegetables, whole grains, and lean proteins can help reduce inflammation and improve overall health.
Stress management: Stress can exacerbate RA symptoms, so finding ways to manage stress such as meditation, deep breathing, or counselling can be helpful.
Getting enough sleep: Getting enough restorative sleep is important for managing RA symptoms, so developing good sleep habits such as sticking to a regular sleep schedule and avoiding caffeine and alcohol before bed can be helpful.
Avoiding smoking: Smoking can increase inflammation and worsen RA symptoms, so quitting smoking or avoiding exposure to secondhand smoke is important.
Using assistive devices: Devices such as canes, splints, and braces can help support the joints and reduce pain and inflammation.
There are several risk factors associated with developing rheumatoid arthritis (RA). These include:
Gender: Women are more likely to develop RA than men.
Age: Although RA can occur at any age, it is most commonly diagnosed between the ages of 40 and 60.
Family history: People with a family history of RA are more likely to develop the condition themselves.
Smoking: Smoking is a major risk factor for RA, particularly in women.
Environmental factors: Exposure to certain environmental factors, such as silica or asbestos, may increase the risk of developing RA.
Obesity: Being overweight or obese may increase the risk of developing RA, as excess weight puts additional strain on the joints.
Hormonal factors: Some evidence suggests that hormonal factors may contribute to the development of RA, as women often experience changes in symptoms during pregnancy or menopause.
Having one or more of these risk factors does not necessarily mean that someone will develop RA, and some people with RA have no known risk factors.
Signs and Symptoms
Rheumatoid arthritis (RA) is a chronic autoimmune disorder that primarily affects the joints, causing inflammation and damage. The signs and symptoms of RA can vary from person to person, but the most common ones include:
Joint pain and stiffness: The pain is usually felt in the joints of the hands, feet, wrists, elbows, knees, and ankles. The stiffness may be worse in the morning and may last for more than an hour.
Swelling and warmth: The affected joints may become swollen, tender, and warm to the touch.
Fatigue: Many people with RA experience a general feeling of tiredness or lack of energy, which can be related to the body’s immune response and inflammation.
Loss of joint function: Over time, RA can cause joint deformity and loss of function, which can make it difficult to perform daily activities.
Rheumatoid nodules: Some people with RA develop small, firm bumps (nodules) under the skin near the affected joints.
Fever: A low-grade fever may be present, especially during flare-ups of the disease.
Weight loss: Some people with RA may experience unintentional weight loss due to decreased appetite or inflammation.
These symptoms can be caused by other conditions as well, and a diagnosis of RA requires a thorough medical evaluation by a healthcare professional.
The treatment for rheumatoid arthritis (RA) aims to reduce inflammation, relieve symptoms, prevent joint damage, and improve overall function and quality of life. Treatment approaches may include:
Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. Disease-modifying antirheumatic drugs (DMARDs) can slow the progression of the disease and reduce joint damage. Biologic DMARDs and Janus kinase (JAK) inhibitors are newer types of drugs that target specific immune system proteins to reduce inflammation.
Physical therapy and exercise: A physical therapist can develop a personalized exercise program to improve joint flexibility, strength, and range of motion. Low-impact activities such as walking, swimming, and cycling are usually recommended.
Occupational therapy: An occupational therapist can help identify ways to modify daily activities to reduce stress on the joints and conserve energy.
Rest and joint protection: Rest and joint protection techniques can help reduce pain and inflammation during flare-ups of the disease.
Surgery: Joint replacement surgery may be necessary for severely damaged joints that are causing pain and affecting function.
Lifestyle changes: Maintaining a healthy weight, eating a balanced diet, and avoiding smoking and excessive alcohol consumption can help manage symptoms and improve overall health.
It’s important to work closely with a healthcare provider to develop a personalized treatment plan for RA that takes into account individual symptoms, disease severity, and overall health.
Who is Affected?
Rheumatoid arthritis (RA) can affect anyone, but it’s more common in women than men. According to the Arthritis Foundation, approximately 1.5 million people in the United States have RA, and about 75% of them are women. RA usually develops in middle age, but it can occur at any age, including childhood.
RA can also run in families, and there may be a genetic predisposition to the disease. Other risk factors for RA include smoking, obesity, and exposure to certain environmental factors, such as pollution and asbestos. However, not all people with these risk factors develop RA, and some people without these risk factors may develop the disease.
