L'arthrite, un fléau des personnes âgées. Does it mean that young people are safe from suffering this illness?
Arthrite is a condition that causes inflammation of the joints and can affect anyone from young children to aged. Elle se caractérise généralement par des douleurs articulaires et une raideur qui rendent les mouvements douloureux et difficiles, though newer treatment options have helped many patients deal more effectively with symptoms. aditionellement, joint health can often be improved with exercise, medication, and the right lifestyle habits.
WHAT CAUSES ARTHRITIS?
Cartilage is a firm but flexible connective tissue in your joints. It protects the joints by absorbing the pressure and shock created when you move and put stress on them. A reduction in the normal amount of this cartilage tissue cause some forms of arthritis.
Normal wear and tear causes OA, one of the most common forms of arthritis. An infection or injury to the joints can exacerbate this natural breakdown of cartilage tissue. Your risk of developing OA may be higher if you have a family history of the disease.
Another common form of arthritis, RA, is an autoimmune disorder. It occurs when your body’s immune system attacks the tissues of the body. These attacks affect the synovium, a soft tissue in your joints that produces a fluide that nourishes the cartilage and lubricates the joints.
RA is a disease of the synovium that will invade and destroy a joint. It can eventually lead to the destruction of both bone and cartilage inside the joint.
The exact cause of the immune system’s attacks is unknown. But scientists have discovered genetic markers that increase your risk of developing RA fivefold.
THERE ARE DIFFERENT TYPES OF ARTHRITIS:
Osteoarthritis is the most common type of arthritis. When the cartilage – the slick, cushioning surface on the ends of bones – wears away, bone rubs against bone, causing pain, swelling and stiffness. Heures supplémentaires, joints can lose strength and pain may become chronic. Risk factors include excess weight, family history, age and previous injury (an anterior cruciate ligament, or ACL, déchirer, par exemple).
When the joint symptoms of osteoarthritis are mild or moderate, they can be managed by:
- balancing activity with rest
- using hot and cold therapies
- regular physical activity
- maintaining a healthy weight
- strengthening the muscles around the joint for added support
- using assistive devices
- taking over-the-counter (OTC) pain relievers or anti-inflammatory medicines
- avoiding excessive repetitive movements
If joint symptoms are severe, causing limited mobility and affecting quality of life, some of the above management strategies may be helpful, but joint replacement may be necessary.
Osteoarthritis can prevented by staying active, maintaining a healthy weight, and avoiding injury and repetitive movements.
A healthy immune system is protective. It generates internal inflammation to get rid of infection and prevent disease. But the immune system can go awry, mistakenly attacking the joints with uncontrolled inflammation, potentially causing joint erosion and may damage internal organs, eyes and other parts of the body. Rheumatoid arthritis and psoriatic arthritis are examples of inflammatory arthritis. Researchers believe that a combination of genetics and environmental factors can trigger autoimmunity. Smoking is an example of an environmental risk factor that can trigger rheumatoid arthritis in people with certain genes.
With autoimmune and inflammatory types of arthritis, early diagnosis and aggressive treatment is critical. Slowing disease activity can help minimize or even prevent permanent joint damage. Remission is the goal and may be achieved through the use of one or more medications known as disease-modifying antirheumatic drugs (DMARDs). The goal of treatment is to reduce pain, improve function, and prevent further joint damage.
A bacterium, virus or fungus can enter the joint and trigger inflammation. Examples of organisms that can infect joints are salmonella and shigella (food poisoning or contamination), chlamydia and gonorrhea (sexually transmitted diseases) and hepatitis C (a blood-to-blood infection, often through shared needles or transfusions). Dans de nombreux cas, timely treatment with antibiotics may clear the joint infection, but sometimes the arthritis becomes chronic.
Uric acid is formed as the body breaks down purines, a substance found in human cells and in many foods. Some people have high levels of uric acid because they naturally produce more than is needed or the body can’t get rid of the uric acid quickly enough. In some people the uric acid builds up and forms needle-like crystals in the joint, resulting in sudden spikes of extreme joint pain, or a gout attack. Gout can come and go in episodes or, if uric acid levels aren’t reduced, ça peut devenir chronique, causing ongoing pain and disability.
