Arthritis is not just one disease; it’s a complex family of musculoskeletal disorders comprising more than 100 diseases or conditions that destroy joints, bones, muscles, cartilage, and other connective tissues, hampering or halting physical movement.
Understanding what causes various forms of arthritis can help people manage their symptoms better and improve their quality of life. This review delves into the causes of arthritis, presented in simple terms for easy understanding.
Arthritis is broadly categorized into two main types: osteoarthritis (OA) and rheumatoid arthritis (RA), each with different causes, and several less common types such as psoriatic arthritis and gout.
Exploring these can provide a broad understanding of how arthritis affects many people in different ways.
Osteoarthritis: OA is often called the ‘wear and tear’ arthritis. It occurs when the cartilage that cushions the ends of bones in your joints gradually deteriorates. Cartilage is a firm, slippery tissue that permits nearly frictionless joint motion.
In osteoarthritis, the smooth surface of the cartilage becomes rough. Eventually, if the cartilage wears down completely, bone will rub on bone. Genetic factors can make some people more likely to develop osteoarthritis of the hands, for example.
However, other factors such as repeated trauma or joint injury and obesity can also contribute to the development of OA, as they add stress to the joint, potentially speeding cartilage breakdown.
Rheumatoid Arthritis: RA is an autoimmune condition, which means it results from your immune system mistakenly attacking your own body’s tissues.
Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity.
The exact trigger of RA is not fully understood, but it is more common in women than men and may be due to a combination of genetic and environmental factors such as smoking.
Genetic Factors: Both OA and RA have a genetic component, meaning they can run in families. For RA, specific genes may increase someone’s chance of developing the condition and potentially its severity.
However, genetic predisposition does not guarantee you will develop arthritis; lifestyle and environmental factors also play a significant role.
Environmental Factors: For RA, environmental factors like smoking and, to a lesser extent, dietary factors can influence who gets the disease and how severe it becomes. Smoking not only increases the risk but can also affect the severity of the disease in people who have a genetic predisposition to RA.
For OA, factors such as joint injuries or occupations that involve repetitive joint stress can exacerbate or accelerate the onset of the disease.
Metabolic Factors: For types of arthritis such as gout, metabolic abnormalities, where the body cannot process certain chemicals properly, leading to the accumulation of uric acid in the joints, result in inflammation and pain. Dietary choices rich in purines like red meat and beer can exacerbate this condition.
Despite its complexity, managing arthritis is possible with current medical advancements. Treatment typically involves a combination of medication, lifestyle changes, physical therapies, and, in some cases, surgery.
Understanding the causes and mechanics behind arthritis can lead to better personal strategies for managing the disease, from diet and exercise adjustments to recognizing early signs and seeking timely medical advice.
Research into arthritis continues to advance, shedding light on the intricate interactions between genetics, environment, and lifestyle, which may lead to more effective treatments and preventive measures in the future.
For those suffering from arthritis, this means hope for less pain, improved function, and a better quality of life.
