Rheumatoid arthritis (RA) - an autoimmune disease that causes inflammation and damage to the joints.

Psoriatic arthritis - a form of arthritis that occurs in people with psoriasis.

Gout - a type of arthritis caused by the buildup of uric acid crystals in the joints.

Lupus arthritis - a type of arthritis that occurs in people with systemic lupus erythematosus (SLE).

Arthritis is diagnosed through a combination of physical examination, medical history, and imaging tests such as X-rays, MRI, or ultrasound. Blood tests can also be used to help diagnose certain forms of arthritis, such as rheumatoid arthritis.

Disability and decreased quality of life.

Increased risk of falls and other accidents.

Increased risk of other health conditions, such as cardiovascular disease.

Treatment for arthritis depends on the type and severity of the condition, as well as the individual patients needs and medical history. 

Pain management, such as over-the-counter pain relievers or prescription medications.

Physical therapy and exercise to maintain joint mobility and strength.

Assistive devices, such as canes or braces, to help with mobility.

Weight management to reduce stress on the joints.

Anti-inflammatory medications or disease-modifying antirheumatic drugs (DMARDs) to slow the progression of arthritis.

It is important to keep in mind that treatment will vary based on the type and severity of the arthritis, and that early and accurate diagnosis and treatment are important for managing the symptoms and preventing long-term joint damage.
