Final answer:
Arthritis causes stiffness and pain in the joints. Osteoarthritis, a form of arthritis linked to aging and wear on cartilage, is the most common type. Treatment can involve lifestyle adjustments and medication.
Step-by-step explanation:
A disease that causes pain or stiffness in your skeletal joints is referred to as arthritis. Arthritis is a common disorder of synovial joints that results in inflammation. This condition can lead to significant joint pain, swelling, stiffness, and reduced joint mobility. Among the over 100 forms of arthritis, osteoarthritis is the most common and is often associated with aging and damage to the articular cartilage. Elements such as physical labor, sports, injuries, and being overweight can exacerbate the stress on joints contributing to osteoarthritis. Treatments may include lifestyle changes and medication, and in some cases, joint replacement surgery might be necessary if the joint damage is severe.
