arthritis is more than just an annoying ache in your hips or hands. it’s actually a term that describes a collection of more than 100 diseases characterized by chronic inflammation in the joints, causing pain and stiffness, according to
arthritis society canada
.
it affects roughly six million canadians and, if left untreated, it can lead to serious damage, culminating in disability.
of the 100 types, there are two broad categories that encompass these many diseases — osteoarthritis (oa) and inflammatory arthritis (ia).
osteoarthritis is the most common, and is caused by the joint deterioration – usually in the knees, hips, hands and spine – that comes with aging, but it can also be caused by injury, obesity, surgery or genetics.
when the cartilage that protects the ends of bones breaks down, bone-on-bone contact creates pain, stiffness, swelling and reduced range of movement.
in the case of inflammatory arthritis, which encompasses rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, juvenile idiopathic arthritis, and gout, joint damage is the result of inflammation.
most forms of inflammatory arthritis are autoimmune diseases, where the immune system attacks its own healthy tissues. it can progress faster and more aggressively than osteoarthritis and, in addition to the joints, it can affect the eyes, skin, lungs and other organs.
