What is lupus?
Lupus is a chronic autoimmune disease that could damage any part of the body (e.g. skin, joints, organs). It is not a communicable disease.
Types of Lupus:
- Systemic lupus erythematosus: the most common type, which can be severe or mild, and can affect various parts of the body.
- Discoid Lupus eryrthematosus: affects the skin in the form of a rash. Could affect any part of the body, but usually appears when exposed to the sun.
- Drug-induced lupus: occurs as a result of some medications, where the symptoms usually disappear within six months of stopping the medication. It rarely impacts the major organs.
- Neonatal lupus (rare): affects newborns as they obtain antibodies from the infected mother's body.
Other names:
Discoid Lupus Erythematosus, systemic Lupus Erythematosus, Lupus
Cause:
Autoimmune diseases occur when the body's immune system attacks its own tissue. Although the cause remains unknown, lupus is likely linked to environmental, genetic and hormonal factors. People who have a genetic predisposition to lupus may develop the disease when stimuli appear, including:

Signs or symptoms could appear suddenly or progress slowly. They could be mild or severe, temporary or permanent. Most patients suffer attacks where the symptoms and signs worsen for some time then improve or disappear completely. Signs and symptoms also depend on the affected systems in the body, including:

- Physical activities could be harmful for lupus patients.
Truth: Light to moderate exercises could be useful for patients, as they could ease joint stiffness and muscle pain
