Full Answer

Arthritis is one of the most common causes of joint swelling, notes Healthline. Forms of arthritis that lead to joint swelling include rheumatoid arthritis, osteoarthritis, septic arthritis, gout and psoriatic arthritis. Rheumatoid arthritis is an autoimmune disease in which the body damages the membrane linings of the joints. This causes fluid to accumulate in the joints, leading to joint inflammation.

Osteoarthritis occurs as a result of gradual wearing out of joint cartilage, a process that occurs naturally with time, says Healthline. The wearing of the cartilage exposes joint bones that rub against each other, resulting in inflammation. Septic arthritis is a form of arthritis that occurs as a result of bacteria or fungi, and may be long-term or short-term. In most cases, acute septic arthritis is caused by staphylococcus and streptococcus bacteria, while chronic septic arthritis results from bacteria Mycobacterium tuberculosis and Candida albicans.

Gout occurs when uric acid accumulates in the joints, causing inflammation and pain, explains Healthline. Psoriatic arthritis is inflammation of the joints that accompanies the skin condition known as psoriasis.
