This large (22m records) cross sub-discipline study found that nearly one in ten people (13% for women and 7% for men) have an autoimmune disease – much higher than historic estimates.
this “research also confirmed that some autoimmune diseases tend to cluster together (for example, one person with a first autoimmune disease is more likely to develop a second autoimmune disease than someone without autoimmune disease), however at a much larger scale and for a much larger set of autoimmune diseases than previous studies.“
