Arthritis refers to inflammation of the joints, leading to pain, stiffness, and reduced mobility. There are many types of arthritis, such as osteoarthritis and rheumatoid arthritis, and treatments vary depending on the cause. These typically include anti-inflammatory medications, physical therapy, and lifestyle changes, but insulin is not used in the management of arthritis. While diabetes and arthritis may both affect older adults and sometimes coexist, their treatment protocols are entirely different. Insulin’s function is related to blood sugar regulation, not joint health. Treating arthritis involves reducing inflammation and preserving joint function — not managing glucose levels.
