Eosinophilic disorders are a class of autoimmune conditions in which a type of white blood cell called eosinophil causes localized irritation, swelling, discomfort, and potentially serious complications in certain tissues. These are often gastrointestinal disorders (EGIDs) affecting the esophagus, stomach, and intestines, and are considered chronic once diagnosed. The incidence of these disorders is sharply on the rise with some estimates that approximately 1% of the developed world is affected, e.g. up to 3 million people in the United States. I'll be using this blog and some ones as a place to capture this design that has taken shape. The purpose here is to document where it came from, why it's relevant and useful, and how you might use it yourself or spread it out into the world for others.
