Lupus diagnosis requires a combination of symptom evaluation, blood tests, and imaging scans, as there is no single definitive test. Doctors look for signs of inflammation, organ damage, and immune system activity to confirm the condition. Treatment typically involves medications like anti-inflammatories, steroids, and immunosuppressants to control symptoms and prevent flare-ups. Lifestyle changes, including stress management, sun protection, and a healthy diet, play a crucial role in improving quality of life. Regular check-ups and early intervention help in managing lupus effectively and reducing long-term complications.
