What is Rheumatoid Arthritis?
Rheumatoid arthritis is a chronic inflammatory autoimmune disorder that primarily affects the joints but can also involve other body systems such as the skin, eyes, lungs, heart, and blood vessels.
In this condition, the immune system mistakenly attacks the body’s own tissues, especially the lining of the joints. This leads to persistent inflammation, pain, swelling, and can eventually result in joint damage, bone erosion, and deformity if left untreated.
While advances in modern medications have significantly improved treatment outcomes, severe or uncontrolled rheumatoid arthritis can still lead to physical disability and reduced quality of life.
Symptoms of Rheumatoid Arthritis
Symptoms of rheumatoid arthritis may vary in severity and often develop gradually. Common signs and symptoms include:
- Tender, warm, and swollen joints
- Joint stiffness, especially in the morning or after periods of inactivity
- Persistent fatigue, fever, and loss of appetite
- Pain and stiffness affecting smaller joints of the hands and feet initially
As the disease progresses, larger joints such as the wrists, knees, ankles, elbows, hips, and shoulders may become involved. In most cases, symptoms affect the same joints on both sides of the body.
Around 40% of individuals may also experience symptoms outside the joints, affecting organs such as the skin, eyes, lungs, heart, kidneys, nerves, and blood vessels.
Causes of Rheumatoid Arthritis
Rheumatoid arthritis is caused by an abnormal immune response in which the immune system attacks healthy joint tissue. This immune-driven inflammation can also affect other organs in the body.
The exact trigger for this immune response is not fully understood. However, genetic factors play a role in increasing susceptibility, and environmental factors such as certain infections may act as triggers in genetically predisposed individuals.
Risk Factors
Several factors may increase the likelihood of developing rheumatoid arthritis, including:
- Gender – women are more likely to develop rheumatoid arthritis than men
- Age – the disease can occur at any age but commonly begins in middle age
- Family history of rheumatoid arthritis
- Smoking, especially in individuals with genetic risk
- Excess body weight, which may increase disease risk and severity
Why Early Diagnosis is Important
Early diagnosis and timely treatment are crucial in rheumatoid arthritis. Prompt medical intervention can help control inflammation, prevent joint damage, reduce complications, and maintain long-term mobility and function.
A rheumatologist plays a key role in diagnosing the condition accurately and creating a tailored treatment plan to manage symptoms and slow disease progression effectively.
