Rheumatoid arthritis (RA) is a chronic inflammatory disease of the joints. Within the body, joints are the points where bones come together and allow for movement. Most of these joints — those called synovial joints — also provide shock absorption.

RA is an autoimmune condition, in which your immune system mistakes the linings of your joints as "foreign" and attacks and damages them, resulting in inflammation and pain.

This disease most often affects the joints of the hands, wrists, and knees symmetrically. There is no cure, but RA can be managed with good treatment, according to the Centers for Disease Control and Prevention (CDC).

Signs and Symptoms of Rheumatoid Arthritis

Rheumatoid arthritis is a complex disease that is not well understood by medical practitioners or researchers.

Early signs of disease, such as joint swelling, joint pain, and joint stiffness, typically begin in a gradual and subtle way, with symptoms slowly developing over a period of weeks to months and getting worse over time. RA usually begins in the small bones of the hands (particularly those at the base and middle of the fingers), base of the toes, and wrists. Morning stiffness that lasts for 30 minutes or more is another hallmark symptom of RA, per the Arthritis Foundation.
RA is a progressive disease. When left untreated, inflammation can start to develop in other parts of the body, causing various potentially serious complications that can affect other organs, such as the heart, lungs, and nerves, and could cause significant long-term disability.

If you're experiencing RA symptoms, it's crucial to get diagnosed as soon as possible so that you can receive prompt treatment.

Causes and Risk Factors of Rheumatoid Arthritis

RA develops when white blood cells, which normally protect the body from foreign invaders such as bacteria and viruses, enter the synovium (the thin tissue that lines the synovial joints). Inflammation ensues — the synovium thickens, causing swelling, redness, warmth, and pain in the synovial joint.

Over time, the inflamed synovium can damage the cartilage and bone within the joint, as well as weaken supportive muscles, ligaments, and tendons.

Researchers don't know exactly what causes the immune system to invade the synovium, but it's believed that genes and environmental factors play a role in the development of RA.

Research suggests that people with certain genetics, namely the human leukocyte antigen (HLA) genes, have a significantly increased risk of developing RA.The HLA gene complex controls immune responses by producing proteins that help the immune system recognize proteins from foreign invaders.
A number of other genes also appear to be associated with RA susceptibility, including STAT4, PTPN22, TRAF1-C5, PADI4, CTLA4, among others, according to a report in the journal Rheumatology.

But not everyone with these identified gene variants develops RA, and people without them can still develop it. So, it's likely that environmental factors often trigger the disease, particularly in people with a genetic makeup that makes them more susceptible to it. These factors include:

  • Viruses and bacteria (though certain infections may reduce RA risk, at least temporarily)
  • Female hormones
  • Exposure to certain kinds of dust and fibers
  • Exposure to secondhand smoke
  • Obesity, which also increases progression of disability for people with RA.Obese patients are less likely to achieve RA remission regardless of the treatment they receive.
  • Severely stressful events
  • Foods
Equally important are smoking and a family history of RA in increasing a person's risk of developing the condition.

Children up to age 16 who experience prolonged swollen or painful joints anywhere in the body are typically diagnosed with juvenile idiopathic arthritis (JIA).

Duration of Rheumatoid Arthritis

RA is a progressive and chronic disease. Damage to the joint bones occurs very early in the progression of the disease, typically within the first two years, according to the Johns Hopkins Arthritis Center.That's why early treatment is so important.
With effective, early treatment, most people with RA can live as they normally would, and many people can achieve remission of symptoms. This doesn't mean that you're cured but rather that your symptoms are alleviated to the point where you can function at your fullest and your joints are not being further damaged by RA. It's also possible to achieve remission and then relapse, or have your symptoms return.

But remission doesn't happen for everyone, and because the pain and other symptoms of RA may change over time, pain management can be an ongoing concern. In addition to pain medications like nonsteroidal anti-inflammatory drugs and corticosteroids, there are many options for pain relief for people living with RA. These include, among others:

  • Fish oil supplements
  • Hot and cold treatments
  • Exercise and movement
  • Mind-body modalities such as mindfulness-based stress reduction and acceptance and commitment therapy
  • Biofeedback

Treatment and Medication Options for Rheumatoid Arthritis

To treat RA, doctors aim to stop the progression of the disease by reducing symptoms, controlling inflammation, minimizing joint and organ damage, and improving physical function.

Proven treatments include medication and physical therapy. Early, aggressive measures can help control symptoms and complications before the disease significantly worsens, by reducing or altogether stopping inflammation as quickly as possible.

This strategy is essential to preventing disability, and it usually amounts to treatment with anti-inflammatory drugs, and sometimes more than one medication at a time.

Medication Options

In recent years, there have been significant advancements in medicines for treating RA, but there is still no cure. Medications known as disease-modifying antirheumatic drugs (DMARDs) are considered the gold standard for RA treatment.

DMARDs can change or slow the progression of the disease, helping prevent severe joint damage and other complications.

In general, these drugs work by slowing the inflammation and protecting the joints from further damage, and are generally prescribed shortly after diagnosis. The type of DMARD a doctor prescribes depends on several factors, including disease severity and the balance between the medication's benefits and potential side effects.

Biologics and JAK inhibitors are newer options alongside traditional DMARDs. Traditional DMARDs target the entire immune system, while biologics work by targeting specific steps in the inflammatory process, and JAK inhibitors block action in your body to help prevent the inflammation before it starts. Traditional DMARDs are usually taken in pill form, as are JAK inhibitors; biologics are typically injected or delivered via an intravenous infusion.

Nonsteroidal anti-inflammatory drugs (NSAIDS) and corticosteroids are used to treat pain and inflammation.But the latest treatment guidelines issued by the American College of Rheumatology recommend that steroid use be minimized.

Alternative and Complementary Therapies for Rheumatoid Arthritis

Certain lifestyle changes and home remedies may be beneficial — in addition to the conventional treatment of medication, physical therapy, and surgery — if needed.

Some people have found relief from RA symptoms through acupuncture, tai chi, and yoga, though the scientific evidence supporting this isn't particularly conclusive. Complementary or alternative therapies, such as homeopathy, hydrotherapy, or cryotherapy, might also be worth considering to help relieve RA pain and stiffness.

Relaxation techniques, visualization exercises, group counseling, and psychotherapy can help reduce the stress of living with RA. Sleeping well is also an important part of managing symptoms.

You should always check with your medical provider before trying any complementary or alternative therapies.

Complications of Rheumatoid Arthritis

It's well established that rheumatic diseases such as RA increase the risks for developing a variety of health conditions.

The most common RA comorbidity is cardiovascular disease, but the condition is also associated with several specific cardiovascular issues, including heart attack, stroke, congestive heart failure, peripheral vascular disease, and atherosclerosis.

It's important for people with RA to work with their doctors to assess their heart disease risk factors, such as high blood pressure, diabetes, and smoking, and to reduce them.

RA can also lead to inflammation in other areas of the body, including blood vessels, where it's known as rheumatoid vasculitis; the lungs, resulting in rheumatoid lung disease or other conditions; the eyes; and the wrists, causing carpal tunnel syndrome.

Another possible complication is kidney impairment as a result of RA medication. And pregnant women need to be aware that RA is linked to pregnancy complications, such as hypertension (high blood pressure) during late pregnancy, and increased risk of premature delivery.

Dietary Modifications to Consider for Rheumatoid Arthritis

While there is a lot of interest in the role of diet and nutrition in symptom management for rheumatoid arthritis, there is no comprehensive research on the topic nor is there a dietary magic formula to fight RA symptoms.

But some evidence suggests that eating certain foods may help reduce inflammation and improve symptoms for some people, while other foods have been shown to worsen inflammation and related symptoms.

For instance, the ketogenic diet — which is high in fats that promote inflammation and low in certain healthy grains, fruits, and vegetables that help fight inflammation — is generally believed to be bad for RA symptoms and pain.

On the other hand, the Mediterranean diet is high in seafood (omega-3 fatty acids) and fiber, which can help fight inflammation. It's sometimes called the anti-inflammatory diet or arthritis diet.
Some research, including a recent review in Frontiers in Nutrition, suggests that diets that exclude animal products completely and focus on vegetables, fruits, and fiber may also be beneficial for RA.

Research and Statistics: Who Has Rheumatoid Arthritis?

About 1 percent of Americans live with rheumatoid arthritis. According to a 2017 report in the journal Rheumatology International, the prevalence of RA in the United States appeared to increase between 2004 and 2014, affecting about 1.3 million adults in 2014.Similar to previous decades, the annual incidence of RA in 2005–2014 was 41 per 100,000 people, and the incidence for women and men was 53 in 100,000 and 29 in 100,000, respectively, according to a study published in the Annals of the Rheumatic Diseases in 2020.
Women are more likely than men to develop RA at an early age, and two to three times as many women as men develop RA, according to the Centers for Disease Control and Prevention (CDC).
Inflammatory arthritis can affect children. It's known as juvenile idiopathic arthritis (JIA), and it affects nearly 300,000 children in the United States, according to the U.S. National Library of Medicine.JIA can't be diagnosed with a blood test, so doctors consider symptoms and medical history to rule out conditions that can resemble JIA, such as infections, cancer, Lyme disease, bone disorders, and lupus.
