Introduction
In general, lupus erythematosus may be caused by factors such as ultraviolet radiation, hormonal changes, chemical irritants, Sjögren's syndrome, or systemic sclerosis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Patients should maintain healthy lifestyle habits, take appropriate sun protection measures, and follow a diet low in fat, sugar, and salt.

Generally, lupus erythematosus may be triggered by factors such as ultraviolet radiation, hormonal fluctuations, chemical exposure, Sjögren's syndrome, or systemic sclerosis. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific causes are analyzed as follows:

1. Ultraviolet Radiation

Prolonged exposure to intense ultraviolet (UV) light may trigger abnormal immune responses and increase the risk of developing lupus erythematosus. When outdoors, it is advisable to use sunscreen, umbrellas, and other sun-protective measures to avoid extended sun exposure.

2. Hormonal Fluctuations

Hormonal changes in women of childbearing age may affect immune system stability, leading to symptoms of lupus erythematosus. It is important to avoid excessive fatigue and emotional stress, monitor hormonal levels regularly, and seek medical advice promptly if abnormalities occur.

3. Chemical Exposure

Long-term contact with chemicals such as hair dyes, fragrances, and preservatives may compromise the skin’s barrier function, causing the immune system to mount an abnormal response against skin cells, potentially triggering lupus erythematosus. Avoiding contact with such chemicals is recommended; when exposure is unavoidable, appropriate protective measures should be taken.

4. Sjögren's Syndrome

Sjögren's syndrome may arise due to genetic factors or immune system dysfunction. Abnormal immune attacks on the body's own tissues may predispose individuals to lupus erythematosus. Common accompanying symptoms include dry skin and dry cough. Treatment may include medications such as urea ointment, hydroxychloroquine sulfate tablets, and levamisole hydrochloride tablets, as prescribed by a physician.

5. Systemic Sclerosis

Systemic sclerosis is primarily associated with genetic and environmental factors. This condition leads to immune system dysregulation, which may damage the body's own tissues and result in the aforementioned symptoms. Symptoms may include thickened skin and hyperpigmentation. Treatment options, guided by a physician, may include prednisone acetate tablets, cyclophosphamide compound tablets, and methotrexate tablets.

Patients are advised to maintain healthy lifestyle habits, adopt appropriate sun protection measures, follow a diet low in fat, sugar, and salt, and avoid direct sunlight exposure, all of which can support recovery and overall well-being.
