Diabetes is a disease that people have known about for thousands of years, even if they didn't call it by that name. Wonderopolis has a simple, helpful overview of diabetes and a quick interview with a young diabetic about how he test his blood. There are actually two types of diabetes with similar symptoms and treatments but different causes. The American Diabetes Association website has information about Type 1 Diabetes, and they also have a free, dowloadable booklet about living with Type 2 diabetes. You can even find statistics about the frequency of diabetes in the United States from the Center for Disease Control.
Symptoms of the disease can be scary, but it helps to know more about what is happening inside the body. Some people take medicine to help control their diabetes, and other people can control it through their diet, choosing recipes and foods that help control their blood sugar levels.
And as always you can contact a librarian for more information!
