Who gets autoimmune diseases?
Autoimmune diseases can affect anyone. Yet certain people are at greater risk, including:
- Women of childbearing age — More women than men have autoimmune diseases, which often start during their childbearing years.
- People with a family history — Some autoimmune diseases run in families, such as lupus and multiple sclerosis. It is also common for different types of autoimmune diseases to affect different members of a single family. Inheriting certain genes can make it more likely to get an autoimmune disease. But a combination of genes and other factors may trigger the disease to start.
- People who are around certain things in the environment — Certain events or environmental exposures may cause some autoimmune diseases, or make them worse. Sunlight, chemicals called solvents, and viral and bacterial infections are linked to many autoimmune diseases.
- People of certain races or ethnic backgrounds — Some autoimmune diseases are more common or more severely affect certain groups of people more than others. For instance, type 1 diabetes is more common in white people. Lupus is most severe for African-American and Hispanic people.
