Lupus, or systemic lupus erythematosus (SLE), is a chronic autoimmune disease where the immune system attacks healthy tissues and organs. It can affect the skin, joints, kidneys, heart, lungs, brain, and blood cells.

Causes
The exact cause of lupus is unknown, but it involves a combination of genetic, environmental, and hormonal factors:
1. Genetics:
A family history of autoimmune diseases increases the risk.
2. Hormonal Factors:
Lupus is more common in women, suggesting a link with estrogen.
3. Environmental Triggers:
Sunlight exposure.
Certain infections (e.g., Epstein-Barr virus).
Stress or trauma.
Exposure to chemicals or toxins.
4. Medications:
Drug-induced lupus can occur with certain medications like hydralazine or procainamide, though it usually resolves once the drug is discontinued.

Effects
1. Chronic Fatigue:
Persistent tiredness affects daily life.
2. Organ Damage:
Long-term inflammation can cause irreversible damage to the kidneys, heart, or lungs.
3. Increased Risk of Infections:
Immune suppression from lupus or its treatments increases susceptibility to infections.

Solutions
Medical Treatments
1. Medications:
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Relieve joint pain and inflammation.
Antimalarials: Hydroxychloroquine reduces skin rashes and joint pain.
Corticosteroids: Control severe inflammation but require cautious use due to side effects.
Immunosuppressants: Drugs like methotrexate, azathioprine, or mycophenolate mofetil help manage severe organ involvement.
Biologics: Belimumab (Benlysta) targets specific immune system components to reduce lupus activity.
2. Regular Monitoring:
Frequent checkups for kidney, heart, and lung health.
