| Rheumatoid Arthritis
		
			| Topic OverviewIs this topic for you?There are many types of
		  arthritis (disease of the joints). This topic is about
		  rheumatoid arthritis. If you are looking for information about how juvenile
		  idiopathic (rheumatoid) arthritis affects young children, see the topic
		  Juvenile Idiopathic Arthritis. If you are looking for
		  information on the most common form of arthritis in older adults, see the topic
		  Osteoarthritis. What is rheumatoid arthritis?Rheumatoid arthritis (RA) causes
		  the
		  joints to become
		  swollen, stiff, and painful (inflamed). Over time, this
		  inflammation may destroy the joint tissues. This can limit your daily
		  activities and make it hard for you to walk and use your hands. 
		  Rheumatoid arthritis is more common in women than in men. It often
		  begins between the ages of 40 and 60.  What causes rheumatoid arthritis?The exact cause is not known. But rheumatoid arthritis is an
		  autoimmune disease. This means that the body's natural
		  defense system attacks the joints. The disease may run in some families. What are the symptoms?The main symptoms of rheumatoid arthritis are pain, stiffness, and
		  swelling in the joints of the hands, wrists, elbows, feet, ankles, knees, or
		  neck. The disease usually affects both sides of the body at the same time. In
		  rare but severe cases, it may affect the eyes, lungs, heart, nerves, or blood
		  vessels. Sometimes the disease
		  can cause bumps called nodules to form over the elbows, knuckles, spine, and
		  lower leg bones. How is rheumatoid arthritis diagnosed?There is no single test for rheumatoid
		  arthritis. Your doctor will do a physical exam and look at your joints for signs of swelling or
		  tenderness. He or she will also ask about your symptoms and past health.  You may have blood tests,
		  X-rays, and other tests to find out if another problem
		  is causing your joint pain.  How is it treated?Treatment  for  rheumatoid arthritis continues throughout your life. It includes medicine,
		  exercise, and lifestyle changes. Getting treatment early may control the condition or keep it from getting worse.  Many of
		  the medicines used to treat rheumatoid arthritis have side effects. So it is
		  important to have regular checkups and talk with your doctor about any
		  problems. This will help your doctor find a treatment that works for you.
		   At home, there are things you can do to relieve your symptoms.  Rest when you are tired. Protect
			 your joints from injury by using devices like special kitchen tools or
			 doorknobs. Use splints, canes, or walkers to ease pain and take
			 stress off your joints if your symptoms are severe. Eat a
			 balanced diet. Exercise regularly. Stay at a healthy
			 weight. 
 If you try medicine, exercise, and lifestyle changes for at least a few years but pain and disability get much worse, surgery may be an option. Total joint replacement of the hip and knee are the most successful.  It can be hard to live with a long-term
		  illness that can limit your ability to do things. It is common for people with
		  rheumatoid arthritis to feel depressed. Your mood can affect how you feel and how well you cope with pain.  Be sure to seek the help and
		  support you need from friends and family members. Professional counseling can also help.Frequently Asked Questions| Learning about rheumatoid arthritis: |  |  | Being diagnosed: |  |  | Getting treatment: |  |  | Ongoing concerns: |  |  | Living with rheumatoid arthritis: |  | 
CauseThe cause of
		  rheumatoid arthritis (RA) is not fully understood.
		  Genes play a role, but experts
		  don't know exactly what that role is. For most people with RA, the disease
		  doesn't run in their families and they don't pass it along to their children.
		  One or more genes may make it more likely that the body's
		  immune system will attack the tissues of the
		  joints. This immune response may also be triggered by
		  bacteria, a virus, or some other foreign substance. Other causes of joint pain include osteoarthritis, lupus, and gout.SymptomsJoint pain can be an early symptom of many
		  different diseases. In
		  rheumatoid arthritis, symptoms often develop slowly
		  over a period of weeks or months. Fatigue and stiffness are usually early
		  symptoms. Weight loss and a low-grade fever can also
		  occur. Joint symptoms include: Painful, swollen, tender, stiff
			 joints. The same joints on both sides of the body
			 (symmetrical) are usually affected, especially the
			 hands, wrists, elbows,
			 feet, ankles, knees, or neck.Morning
			 stiffness. Joint stiffness may develop after long periods of sleeping or
			 sitting. It usually lasts at least 1 hour and often up to several
			 hours.Bumps (nodules). Rheumatoid nodules ranging in
			 size from a pea to a mothball develop in nearly one-third of people who have
			 rheumatoid arthritis.
			 Nodules usually form over pressure points in the body
			 such as the elbows, knuckles, spine, and lower leg bones.
 In addition to specific joint symptoms, rheumatoid arthritis can cause
		  symptoms throughout the body (systemic). These include: Fatigue.A loss of
			 appetite.Weight loss.Mild fever.
 Some of the symptoms of rheumatoid arthritis may be similar
		  to symptoms of other health conditions. More informationWhat HappensThe course of
		  rheumatoid arthritis is hard to predict. It usually progresses slowly, over months or years. In some people it doesn't get worse, and symptoms stay about the same. But in rare cases, symptoms come on rapidly, within days.   Symptoms can come and go. You may have times in your life when joint pain goes away on its own for a while. This is called remission. If the disease progresses, joint pain can
		  restrict simple movements, such as your ability to grip, and daily activities,
		  such as climbing stairs. It is a common cause of permanent
		  disability. But early treatment may control the disease and keep it from getting worse. Rheumatoid arthritis is more likely to get worse when: A rheumatoid factor blood test is
			 positive.A blood test for the antibody CCP (cyclic citrullinated
			 peptide) is positive.The disease fails to respond to
			 therapy.Bumps (nodules) form rapidly.Many
			 joints are affected.X-rays show early
			 loss of bone or
			 cartilage.
 Joint damageThe ongoing inflammation caused by rheumatoid arthritis affects the tissues that line joints. It causes a breakdown in cartilage and loosens ligaments and tendons that support the joints. The resulting joint destruction can lead to deformed joints.  The pain, stiffness, fatigue, and
			 whole-body (systemic) symptoms of rheumatoid arthritis can be
			 disabling. Over time, the deformity caused by the disease can lead to difficulty with daily activities.
			 Specific joint problems may also occur later in the course of the
			 disease. The hands and wrists and feet  may be deformed. The hands are the most common location for
			 deformities.  Inflammation of the knees, if not controlled by
			 treatment, can cause erosion of cartilage and can later lead to the need
			 for knee replacement surgery. Rheumatoid arthritis can also damage  the cervical spine, or neck. This damage can limit how easily you can move your neck. In rare cases, the
			 damage can pinch a nerve or affect the spinal cord and cause numbness, pain, weakness, or paralysis in the arms or legs.  Other problems In a small number of severe cases,  the disease may damage other organs, such as the eyes and lungs. People who have rheumatoid arthritis seem to develop plaque deposits in arteries (atherosclerosis) earlier than people who do not have rheumatoid arthritis. Inflammation may play a role in speeding up plaque development. When plaque develops in the arteries in the heart,  it is called coronary artery disease (CAD) and it increases the risk of a heart attack. When plaque develops in the arteries in the neck, it increases the risk of stroke. Rheumatoid arthritis and some of the medicines used to treat it can increase the risk of osteoporosis. It is common for people with rheumatoid arthritis to feel  depressed. These feelings may be caused by pain and
		  progressive disability.  Most women with rheumatoid arthritis can become pregnant and have a healthy baby.What Increases Your RiskThings that may increase
		  your risk for rheumatoid arthritis include: Being female. Rheumatoid arthritis affects
			 women 2 to 3 times as often as men.Being
			 middle-aged. Rheumatoid arthritis can begin at any age, but
			 it most often begins in adulthood.Smoking cigarettes.
When to Call a DoctorCall your doctor immediately if you have: Sudden, unexplained swelling and pain in any
			 joint or joints.Joint pain associated
			 with a fever or rash.Pain that is so severe that you cannot use
			 the joint.Back or neck pain along with weakness in your arms or legs.Loss of bowel or bladder control.
 Call your doctor within the next few days if
		  you have: Joint pain that continues and
			 has not improved for over 6 weeks.Side effects that occur with
			 large doses of
			 nonsteroidal anti-inflammatory drugs (NSAIDs) or other
			 medicine used to treat your arthritis. NSAIDs include ibuprofen (Advil) and naproxen (Aleve).
 Watchful waitingWatchful waiting is a wait-and-see approach. It is reasonable to try home
			 treatment for mild joint pain and stiffness. If there is no improvement after 6
			 weeks, or if any other symptoms are present, call your doctor. Early treatment can slow and sometimes prevent significant joint damage.
			 So if you have symptoms similar to rheumatoid arthritis, see
			 your doctor to find out if you have rheumatoid arthritis.
			 Early diagnosis and treatment allows for possible reduction of joint pain,
			 slows joint destruction, and reduces the chance of permanent disability. Who to seeEarly arthritis symptoms can be
			 diagnosed by: Rheumatoid arthritis can be treated by: A rheumatologist.A family medicine doctor or an internist who consults with a rheumatologist.
 Supportive treatment can be provided by:Exams and TestsNo single lab test can diagnose
		  rheumatoid arthritis. Instead, doctors look at symptoms and physical signs and then rule out other diseases that
		  can cause similar symptoms.  A
		  medical history and physical exam are usually
		  done to help find the cause of joint pain. The pattern and nature of
		  joint symptoms are the most important clues
		  to the diagnosis. Diagnosis is based on a set of
		  classification criteria. The criteria include the results of these tests: Other tests are used to help monitor and manage rheumatoid arthritis. These include: Regular checkupsBecause rheumatoid arthritis can lead to severe joint
		  destruction and disability over time, regular checkups are important to see if treatment is working or
		  needs to be adjusted.Treatment OverviewRheumatoid arthritis is most often treated with medicine, exercise, and lifestyle
		  changes. Treatment may help relieve symptoms and control the disease, but there
		  is no cure. Treatment for rheumatoid arthritis usually continues throughout
		  your life, but it will vary depending on: The stage (active or in
			 remission) and severity of your
			 disease.Your treatment history.The benefits and risks
			 of treatment options.Your preferences for treatment options, such
			 as cost, side effects, and daily schedules.
 The goal of treatment is to help you maintain your
		  lifestyle, reduce joint pain, slow joint damage, and prevent disability.
		   Making a planTreatment
		  of
		  rheumatoid arthritis should start with education about
		  the disease, the possibility of joint damage and disability, and the risks and
		  benefits of potential treatments. A long-term treatment plan should be
		  developed by you and your team of doctors. Treatment with medicinesEarly and ongoing treatment of
		  RA with medicines called disease-modifying antirheumatic
		  drugs (DMARDs)  can slow or sometimes prevent joint
		  destruction.  Other medicines may be combined with DMARDs to relieve symptoms. These medicines include: Medicines that reduce swelling, including ibuprofen (such as Advil or Motrin) and naproxen (such as Aleve or Naprosyn).
 Medicines that relieve pain, such as acetaminophen, codeine, and hydrocodone.  Corticosteroids for early treatment, to control flare-ups, or to help manage the disease. 
 Be safe with medicines. Read and follow all instructions on the label. For more information, see Medications. Lifelong careTreatment for
		  rheumatoid arthritis usually continues throughout your
		  life. Your doctor will want to closely monitor your condition. A
		  rheumatologist should evaluate you regularly. Depending on your symptoms and
		  treatment, this could be done as often as every 2 to 3 months or every 6 to 12 months. Testing, such as blood tests, may be done
		  more often.  During each follow-up visit, your doctor will assess: The amount of joint pain.How long
			 morning stiffness lasts.The number of actively inflamed
			 joints.How well you are functioning.Results of lab  tests. 
 In some cases, the disease does not respond to
		  the first several treatments. When this happens, the disease may be
		  treated with much higher doses of medicines or with different combinations of
		  medicines.  Surgery may be considered when the joints-especially the hips,
		  knees, or feet-are severely damaged or deformed and are causing extreme pain.
		  Surgery may include total joint replacement or other techniques to improve
		  joint function. For more information, see Surgery and Other Treatment. Exercise and lifestyle changesExercise, physical therapy, and lifestyle
		  changes can help relieve joint pain. Many people with RA
		  benefit from self-care plans that balance rest and activity. You can take steps at home to relieve your symptoms and help control your disease. For more information, see Living With Rheumatoid Arthritis. Living With Rheumatoid ArthritisLiving with
		  rheumatoid arthritis  often means making changes to
		  your lifestyle. You can do things at home, such as staying active and taking
		  medicines, to help relieve your symptoms and prevent the disease from getting
		  worse.  Arthritis: Managing Rheumatoid Arthritis
 You can also plan for those times when the disease symptoms
		  may be more severe. It is important to work closely with your health
		  professionals, who may include a
		  physical therapist or counselor, to find ways to
		  reduce pain.  Rest when you're tired The disease itself causes fatigue. And the
		  strain of dealing with pain and limited activities also can make you tired. The
		  amount of rest you need depends on how bad your symptoms are. With severe symptoms, you may need long periods
			 of rest. You might need to rest a joint by lying down for 15 minutes several
			 times a day to relax. Try to find a balance between daily
			 activities that you must do or want to do and the amount of rest you need to do those activities. Plan your day carefully, including
			 rest periods. Pace your activities so that you don't get
			 overtired.
 Protect your joints
		  You may need to change the way you do certain activities so that you are not
		  overusing your joints. Try to find different ways to relieve your joint
		  pain. Joint pain and stiffness may improve with heat
			 therapy, such as: 
			 Taking warm showers or baths after long
				  periods of sitting or sleeping.Soaking hand joints in warm wax
				  baths.Sleeping under a warm electric blanket.
Use
			 assistive devices to reduce strain on your joints,
			 such as special kitchen tools or doorknobs.Choose the right shoes that fit well and will not cause joint problems.Use splints, canes, or
			 walkers to reduce pain and improve function.
 Stay activeKeep moving to
		  keep your muscle strength, flexibility, and overall health. Physical therapy may be recommended by
			 your doctor.Exercise for arthritis takes three forms-stretching,
			 strengthening, and conditioning. Exercise can improve or maintain quality of life for people who have rheumatoid arthritis. Your specific joint problem may
			 guide the type of activity that will help the most. For example: 
			 Swimming is a good activity if
				  you have joint problems in your knees, ankles, or
				  feet.Bicycling and walking are good activities if your
				  joint problems are not in your legs or feet. 
 Avoid smokingPeople with rheumatoid arthritis have an increased risk of plaque in the arteries (atherosclerosis). Smoking increases this risk even more. Smoking may also lower your response to treatment.footnote 1 So, if you're a smoker, quit. For more information on how to quit, see the topic Quitting Smoking. Eat healthy foodsTry to eat a variety of healthy foods. Dietary needs are not the same for all people who have rheumatoid arthritis. To be sure you get the nutrients you need, you can ask a registered dietitian to help you make a plan.  Be sure to get enough
			 calcium and
			 vitamin D to protect your bones against osteoporosis.
			 For more information, see the topic
			 Osteoporosis.Lose weight, if you are
			 overweight. For more information, see the topic
			 Weight Management.People who have rheumatoid arthritis also have an increased
		  risk of heart disease. But healthy lifestyle changes, such as exercise and a
		  healthy diet, may reduce your risk.
		  
 For more information, see: Take care of your teeth and gumsPeople who have rheumatoid arthritis tend to get gum disease. Some experts think that infection that enters the body through the mouth may make rheumatoid arthritis worse, although this has not been proved. You can help prevent gum disease through good basic dental care.  Dental Care: Brushing and Flossing Your Teeth
MedicationsMedicines are the main treatment for
		  rheumatoid arthritis. The types of medicines used
		  depend on how severe your disease is, how fast it is progressing, and how it
		  affects your daily life. If your symptoms ease, you and your
		  doctor will decide if you can take less medicine or stop taking medicine.
		  If your symptoms get worse, you will have to start taking medicine again.
		   Medicines are used to: Relieve or reduce pain.Improve
			 daily function.Reduce joint inflammation. Signs of joint
			 inflammation include swelling, tenderness, and limited range of
			 motion.Prevent or delay significant
			 joint damage and deformity.Prevent
			 permanent disability.Improve quality of life.
 Medicines called disease-modifying antirheumatic drugs
		  (DMARDs) can slow or sometimes prevent joint destruction. Starting treatment early with DMARDs can reduce the severity of the disease. DMARDs are also called immunosuppressive drugs or
		  slow-acting antirheumatic drugs (SAARDs). These medicines are usually taken over a long period to help control the disease.  DMARDs can be thought of as nonbiologic or biologic, depending on how they are made and how they act in the body. But they are all used to block harmful responses from the body's immune system. DMARDs are sometimes combined with one another or with other medicines. By combining medicines, you may be able to take lower doses of individual medicines. This may reduce your risk of side effects. Some medicines for rheumatoid arthritis may cause birth defects. If you
		  are pregnant or are trying to become pregnant, talk with your doctor about your medicines. Medicines to slow the diseaseDisease-modifying antirheumatic drugs
			 (DMARDs) are usually started within 3 months of your diagnosis. They are used to
			 control the progression of RA and to try to prevent joint
			 damage and disability. DMARDs are often given in combination with other
			 medicines. Commonly used nonbiologic DMARDsAntimalarials such as
				hydroxychloroquine or chloroquineLeflunomideMethotrexateSulfasalazine
 Less commonly used nonbiologic DMARDsAzathioprineCyclophosphamideCyclosporineGold saltsMinocyclinePenicillamine
 Biologic DMARDs (biologics)AbataceptAdalimumabAnakinraCertolizumabEtanerceptGolimumabInfliximabRituximabTocilizumab
 There is a newer biologic drug called tofacitinib (Xeljanz) for adults who have moderate to severe rheumatoid arthritis. This medicine is for people who have not responded well to methotrexate or who cannot take it. Tofacitinib is taken by mouth. It reduces the symptoms of rheumatoid arthritis and allows people to be more active. But the long-term safety of this medicine is still being studied.footnote 2, footnote 3 Medicines to relieve symptomsNonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, and naproxen. NSAIDs are used to
				control pain and may help reduce inflammation. They don't control the disease
				or stop it from getting worse. NSAIDs may be combined with DMARDs.Corticosteroids
				such as prednisone. These medicines are used to reduce disease
				activity and joint inflammation. But using only corticosteroids for an extended time is not considered the best treatment. Corticosteroids are
				often used to control symptoms and flares of joint inflammation until DMARDs
				reach their full effectiveness.Analgesics (pain relievers). These don't reduce
				inflammation but may help with pain control. They include: 
				Nonprescription
				acetaminophen. Acetaminophen with codeine (such as
					 Tylenol with codeine).Acetaminophen with hydrocodone (such as
					 Vicodin).Tramadol.
 What to think aboutSome DMARDs can take up to 6
			 months to work.In some people, a certain DMARD may not work at all. So a
			 different DMARD will be used.If you're taking DMARDs, it's a good idea to have a rheumatologist manage your care. Many DMARDs have serious side effects. You will need regular blood and urine tests to check the drug's effects on
			 blood-producing cells (bone marrow), the kidneys, and the liver.If you have other conditions such as high blood pressure or high cholesterol, your doctor may recommend that you take medicine to control them.
 Be safe with medicines. Read and follow all instructions on the label.SurgerySurgical treatment for
		  rheumatoid arthritis is used to relieve severe pain
		  and improve function of severely deformed joints that don't respond to
		  medicine and physical therapy.  Total joint replacement
		  (arthroplasty) can be done for many different joints in the body. Its success
		  varies depending on which
		  joint is replaced. Surgery choicesSurgeries considered for people
			 who have severe rheumatoid arthritis include: What to think aboutJoint surgery often restores
			 near-normal movement in a person who has
			 osteoarthritis in just one or two joints. But this is
			 not the case for people affected by rheumatoid arthritis. Rheumatoid arthritis usually affects multiple
				joints, particularly smaller joints, such as finger joints, which are needed
				for many daily activities. Surgical treatment may not be an option for all of
				the affected joints.Joint surgery or replacement can relieve
				disabling pain and restore enough motion to allow you to do your daily
				activities. But it will seldom restore the joint to normal.
 Before you decide to have surgery, consult with an
			 orthopedic surgeon who is experienced in joint surgery
			 for rheumatoid arthritis.

Other TreatmentOther types of treatment that may
		  help you control some of the symptoms of
		  rheumatoid arthritis   include: Complementary medicineComplementary medicine therapies are
			 used by many people to relieve symptoms and
			 improve their quality of life, even though there isn't strong scientific evidence that they help. These therapies include: Acupuncture. This treatment is used to
				relieve pain and treat certain health conditions. It is done by inserting very
				thin needles into the skin at specific points on the body.Herbs and dietary supplements. If you decide to
				use herbs or dietary supplements, be sure to tell your doctor. 
				Herbs such as the oil of evening primrose, borage seed, or blackcurrant seed may help relieve symptoms and improve function without significant side effects.Essential fatty acids (such as fish oil) may provide some
					 relief of symptoms.footnote 4 The dietary supplements glucosamine and chondroitin are sometimes used to
					 try to relieve joint pain. But there is not evidence that they are effective for rheumatoid arthritis.
Massage. It can help relieve stress and reduce
				pain. But don't massage swollen or painful joints.
 Find out about the safety of any complementary product or practice you want to try. Most mind and body practices-such as acupuncture and massage-are safe when used under the care of a well-trained professional. Choose an instructor or practitioner as carefully as you would choose a doctor. Talk with your doctor about any complementary health practice that you would like to try or are already using. Your doctor can help you manage your health better if he or she knows about all of your health practices.Other Places To Get HelpOrganizationNational Institute of Arthritis and Musculoskeletal and Skin Diseases (U.S.) www.niams.nih.govReferencesCitationsO'Dell JR (2013).
