January 25, 2024

Key points

• Rheumatoid arthritis (RA) causes pain, swelling, and stiffness in the joints.
• There’s no cure for RA, but you can manage and treat it with medicines and lifestyle changes.
• It’s best to diagnose and treat RA early to avoid joint damage and worsening symptoms and complications.
• Doctors diagnose RA through a physical exam, X-rays, lab tests, and a review of a patient’s health history.

Overview

RA is an autoimmune disease

• RA is a disease in which the immune system attacks the body’s own tissues.
• This causes damage to the joints in the hands, wrists, and knees.
• The damage from RA can result in:
  • Long-lasting (chronic) pain.
  • Swelling.
  • Balance issues.
  • Deformed joints.
• RA can also affect the lungs, heart, and eyes.

RA limits physical activities and social connections

• RA can limit enjoyment of some life activities.
• People with RA may experience social isolation.
• RA can make it hard to do physically demanding or fast-paced work.

RA can be managed

• There is no cure for RA. But it can be managed.
• You can practice self-care and take medicines to reduce pain and limit complications.

Signs and symptoms

RA symptoms include:

• Pain, aching, or stiffness in more than one joint.
• Tenderness, redness, warmth, and swelling in joints.
• Weight loss.
• Fever.
• Fatigue or tiredness.
• Weakness.

Flares and remission

People with RA may experience:

• Flares—when symptoms suddenly appear or get worse.
• Remission—when symptoms get better or go away.

Things that increase risk for RA

The causes of RA are not known.

Smoking

Smoking can increase your risk of getting rheumatoid arthritis and can make arthritis worse.

Smoking can also make it harder to be physically active, which is important for managing arthritis symptoms.

Factors linked to RA

Factors that may be linked to RA:

• Age—RA risk increases as people get older. It’s highest among adults 50 to 59.1
• Sex—Women are two to three times more likely to have RA.1 Women who haven’t given birth may have a greater risk of RA.
• Early life exposures—Children whose parents smoked were more likely to develop RA as adults.2 Also, adults from lower-income families may have a higher risk of RA.3
• Family history—Certain genes can increase the risk of RA, such as the human leukocyte antigen (HLA) class II gene.

Diagnosis

Finding out if you have RA

Doctors can diagnose RA by doing:

• A physical exam.
• X-rays.
• Lab tests.
• A review of your health history.

Expert Care

It’s important to get diagnosed with RA as soon as possible so you can start treatment.

• Rheumatologists—doctors who specialize in arthritis care—should diagnose and treat RA.
• Early treatment helps prevent symptoms from getting worse and doing damage to your joints.
