Rheumatology deals with disorders affecting joints, muscles, and connective tissues, often caused by autoimmune reactions. Conditions like rheumatoid arthritis, lupus, and psoriatic arthritis result from the immune system attacking healthy tissues, leading to pain, stiffness, and inflammation.

Early diagnosis and proper management help prevent complications. Treatments include anti-inflammatory drugs, immunosuppressants, and biologics, along with lifestyle changes like exercise and a balanced diet. Managing stress and regular medical check-ups are essential for improving quality of life.
