Understanding Arthritis and Its Impact

Arthritis is a chronic condition characterized by inflammation of the joints, leading to pain, stiffness, and limited mobility. It affects millions of people worldwide, significantly impacting their quality of life.

The term "arthritis" is derived from the Greek word "arthron," which means joint, and "itis," which refers to inflammation. There are various types of arthritis, each with its own unique characteristics and impact on the body.

‍

Definition of Arthritis

Arthritis refers to a group of diseases that result in joint inflammation. It can affect one or multiple joints, leading to symptoms such as pain, swelling, and limited range of motion. The most common forms of arthritis include osteoarthritis, rheumatoid arthritis, and psoriatic arthritis.

While the exact causes of these conditions vary, they all involve an immune system response that targets the joints, resulting in the characteristic symptoms.

‍

Types of Arthritis

There are several types of arthritis, each with its own distinct characteristics and manifestations. Osteoarthritis, the most common type, occurs when the protective cartilage that cushions the ends of bones wears down over time.

Rheumatoid arthritis is an autoimmune disorder in which the immune system mistakenly attacks the synovium, the lining of the joints. Another form, psoriatic arthritis, occurs in individuals with psoriasis, an autoimmune skin condition. Other types include gout, infectious arthritis, and juvenile arthritis.

‍

Prevalence of Arthritis

Arthritis is a widespread condition that affects people of all ages, sexes, and ethnicities. According to the World Health Organization, it is estimated that over 350 million people suffer from arthritis worldwide. It is more prevalent among older adults, with the risk increasing with age.
