Arthritis – Types, signs and risk factors
Arthritis is a medical condition that is marked by inflammation in the joints. It can affect a single joint or several joints in the body. There are different types of arthritis. Each one can be traced to a different cause, with various methods to treat them. Types Primarily, there are two main kinds of arthritis – rheumatoid arthritis and osteoarthritis. These can be broken down into several categories. Osteoarthritis This is the most commonly diagnosed form of arthritis. When a person is suffering from osteoarthritis, the cartilage of the joints gets severely damaged. The cartilage is the tough, coarse protective coating found at the end points where the bones come together to form a joint. Cartilage acts as a cushion to this part of the bones and facilitates the frictionless movement of the joints. When the cartilage gets damaged, the bones grind against each other, causing severe pain and restrictive movements. This damage can take place over a few years or in a short time. Rheumatoid arthritis In this type of arthritis, the immune system adversely affects the outer covering or the lining around the joint capsule. The joint capsule is a hard membrane that surrounds parts of the joints.
