It can only be managed through medication to control the progression of the disease, prevent relapses, delay damage to other organs, and prevent complications. This is the overall principle of treatment. Its cause is currently unclear. It is only related to factors such as environmental pollution, viral infections, genetics, and hormones, according to expert research. However, there is no specific definitive cause identified.

What causes systemic lupus erythematosus?

Systemic lupus erythematosus mainly has four major causes: The first is related to the environment. Long-term exposure to sunlight, or living in a humid environment, may trigger the onset of systemic lupus erythematosus. Secondly, there is a certain genetic predisposition to systemic lupus erythematosus. If the parents have systemic lupus erythematosus, the probability of their offspring developing the disease is higher. Thirdly, systemic lupus erythematosus is also related to estrogen, which is why, clinically, lupus is more commonly seen in women of childbearing age and less often in men. Systemic lupus erythematosus is also associated with some specific infections, such as bacterial or viral infections, which may trigger a lupus flare-up.

Can people with systemic lupus erythematosus eat black fungus?

Systemic lupus erythematosus is an autoimmune disease that affects multiple systems and organs. It cannot be cured and can only be managed through medications to control the progression of the disease and delay complications. It commonly occurs in women of childbearing age. In the early stages, when no other organs are damaged, there are no special dietary restrictions and black fungus can be eaten. However, fruits such as figs and bayberries, which are exposed to ultraviolet light for a long period, should be avoided. If the disease affects the kidneys causing damage such as proteinuria and increased creatinine, a diet low in salt, fat, and restricted in high-quality protein is necessary. High-quality protein mainly refers to lean meats and pure milk, and consumption of black fungus should be moderated.

Initial symptoms of systemic lupus erythematosus

Systemic lupus erythematosus is an autoimmune disease that affects multiple systems and organs and is associated with a variety of autoimmune antibodies, primarily occurring in women of childbearing age. Its clinical manifestations are diverse, with the condition being mild and recurrently evolving. The most common symptoms involve changes to the skin, where various types of edematous erythema can occur, and in severe cases, there can be blisters, ulcers, erosion, skin atrophy, hyperpigmentation, and scar formation. Among these, the butterfly rash is most specific. Additionally, other symptoms may include joint swelling and pain; kidney involvement can lead to foamy urine, which is a common presentation; gastrointestinal involvement can cause diarrhea, and neurological involvement can lead to mental disorders and seizures. Therefore, once facial rashes, photosensitivity, or joint swelling and pain occur, it is crucial to be vigilant, undergo relevant examinations promptly, diagnose early, and treat early, as it is very important for the prognosis of the disease.

Systemic lupus erythematosus is not contagious.

Systemic lupus erythematosus is a chronic autoimmune disease that can damage multiple systems and affect multiple organs. Its occurrence is related to genetics, environmental pollution, hormonal levels, and infections. It is classified as an autoimmune disease and is not infectious or contagious. Once diagnosed with systemic lupus erythematosus, it is important to thoroughly complete related examinations and assess the activity level of the disease, as treatment plans vary accordingly. Therefore, for patients with systemic lupus erythematosus, there is no need to worry about it being contagious. However, there is a hereditary tendency, meaning if the parents have it, the likelihood of their children developing the disease is significantly higher than others.

What is the best food to eat for systemic lupus erythematosus?

Firstly, systemic lupus erythematosus is an autoimmune disease that can affect multiple systems and organs and cannot be cured. It can only be managed through medications to control the progression of the disease and delay the onset of complications. Therefore, it's not about what food is good for lupus, but rather about managing any complications it may have. Some foods to avoid include tomatoes, bayberries, figs, celery, bananas, as well as other fruits and vegetables that have been exposed to prolonged sunlight. The general principle is to adopt a low-salt, low-fat diet while increasing the intake of high-quality proteins, primarily lean meats and pure milk, to boost resistance and immunity.
