What is lupus?
Lupus is a long-term autoimmune condition. It occurs when the body’s immune system mistakenly attacks healthy tissues rather than protecting them. This can lead to inflammation in many parts of the body, including the skin, joints, and major organs.
Lupus develops when the immune system becomes overactive and attacks the body’s own cells. The exact cause is not fully understood, but several factors may play a role:
- Genetics
- Hormonal influences
- Environmental triggers like infections, stress, or sun exposure
It is most often diagnosed in women during their childbearing years, but it can affect anyone, including children.
Symptoms
Lupus can affect each person differently. Some people have mild symptoms, while others may experience more serious health concerns.
Common symptoms include:
- Ongoing fatigue
- Joint pain or swelling
- Skin rashes, especially across the cheeks and nose
- Sensitivity to sunlight
- Fever
- Hair thinning or loss
- Mouth or nose sores
- Cold or color changes in fingers and toes
- Unexplained weight loss
How is it diagnosed?
Lupus can be challenging to diagnose because its symptoms may resemble those of other conditions and can develop slowly.
Your provider will begin by reviewing your symptoms and health history. Blood tests are commonly used to look for specific antibodies and signs of inflammation. Urine tests may be done to check how well your kidneys are working.
In some cases, imaging tests or a small tissue sample (biopsy) may be needed to understand better how the disease is affecting your body.
How is it treated?
There is no cure for lupus, but treatment can help control symptoms and protect your organs.
Care usually starts with medications to reduce inflammation and ease discomfort. These may include:
- Anti-inflammatory medicines for pain and swelling
- Medications that calm the immune system
- Steroids for more serious inflammation
- Targeted therapies for advanced disease
Healthy lifestyle habits are also an important part of care. Getting enough rest, eating well, staying active, managing stress, and protecting your skin from the sun can all help reduce flare-ups.
Because lupus can affect different parts of the body, you may work with a team of specialists. With the right care plan, many people can manage their symptoms and live full, active lives.
