Many kids are diagnosed with it when they're between 6 months and 2 years old. It makes sense because, at this time kids are getting their first taste of gluten in foods.
For some people, the problems occur gradually and the symptoms may be terrible one week and not as bad the next. Because of this, some people aren't diagnosed with celiac disease until they're older. The problem is chronic, which means that although symptoms may come and go, people who have celiac disease will always have it.
Someone with celiac disease may feel tired and could be irritable. Some also have skin rashes and mouth sores.
