What is lupus?

Lupus, also known as systemic lupus erythematosus (SLE), is an autoimmune disease in which the immune system mistakenly attacks healthy tissues and organs in the body, leading to inflammation and a range of symptoms that can affect various parts of the body, including the liver, blood, skin, joints, kidneys, heart, lungs, and brain.

What are the different types of lupus?

1. Systemic Lupus Erythematosus (SLE): An autoimmune disease where the immune system attacks various organs and tissues in the body. Most common type of lupus.
2. Cutaneous Lupus Erythematosus (CLE): Primarily affects the skin, leading to rashes and skin lesions, with subtypes triggered by sunlight.
3. Drug-Induced Lupus: Occurs as a reaction to certain medications, mimicking SLE symptoms but typically resolving when the medication is stopped.
4. Neonatal Lupus: A rare condition in newborns caused by maternal autoantibodies, often associated with skin rashes, liver issues, and heart defects that typically improve over time.

Who is at risk of developing lupus?

1. Gender: Lupus is more common in women than in men. According to the Lupus Foundation of America, approximately 90% of individuals with lupus are women. (Source)
2. Age: While lupus can develop at any age, it often appears in individuals between the ages of 15 and 44. (Source)
3. Family History: A family history of lupus or other autoimmune diseases may increase the risk. Having a close relative with lupus, such as a parent or sibling, can elevate the likelihood of developing the condition.
4. Ethnicity: Lupus has been found to be more common in certain racial and ethnic groups, including African Americans, Hispanics, Asians, and Native Americans. These groups may have a higher risk of developing lupus and experiencing more severe symptoms. (Source)

What causes lupus?

The exact cause of lupus is not fully understood, but it is believed to be a complex interplay of genetic, hormonal, environmental, and immunological factors. Genetics play a role, as some individuals may have a genetic predisposition to develop lupus. Hormonal factors, such as the influence of estrogen, also appear to be involved, given the higher prevalence in women. Environmental triggers, such as exposure to sunlight, infections, and certain medications, may contribute to the development of lupus in genetically susceptible individuals.
