Rheumatoid arthritis (RA) is a prevalent autoimmune disorder marked by chronic inflammatory arthritis and systemic effects. The etiology of RA is complex, involving genetic factors like HLA-DR4 and HLA-DR1, as well as environmental influences, particularly smoking, which heightens disease risk. Affecting approximately 1% of the global population, RA is associated with considerable morbidity and mortality, with its prevalence expected to increase due to demographic shifts, especially in certain regions. RA symptoms commonly manifest between ages 35 and 60 but can also affect children under 16 in cases of juvenile RA. Symptoms include prolonged joint stiffness, pain, fatigue, and, in advanced cases, joint deformities. Current treatment approaches involve disease-modifying antirheumatic drugs, biologics, and glucocorticoids to manage symptoms and slow disease progression, though these treatments often present limitations due to adverse effects and varied patient response. The identification of genetic markers, such as HLA-DRB1 and PTPN22, supports the growing emphasis on personalized treatment strategies that account for genetic and lifestyle factors. Non-pharmacological approaches - diet adjustments, physical activity, and stress management - are increasingly valued for their complementary role in RA management. Lifestyle interventions, including whole-food, plant-based diets and physical therapy, show promise in reducing inflammation and improving joint function. Technological advancements, like telemedicine, mobile health applications, and artificial intelligence, are enhancing RA diagnosis and treatment, making care more precise and accessible. Despite these advancements, RA remains incurable, necessitating continued research into novel therapeutic targets and approaches. A comprehensive, patient-centered approach that integrates lifestyle modifications, preventive strategies, and innovative treatments is essential for improving RA management and patient outcomes.
