9,000,000 people in Germany and Austria are affected by diabetes. Many struggle with their weight, feel unwell, and are often thirsty. This is the reality for many—nine million Germans and Austrians suffering from these symptoms know they have diabetes. Experts agree that the actual number is likely much higher. Diabetes can affect anyone, and the number of those affected is steadily increasing. However, the disease, even though it "doesn't go away," is highly treatable and manageable. In the best case, it can even be prevented. The most important prerequisite for prevention or managing diabetes is, of course, the necessary knowledge—and that is far less widespread than one might think. Therefore, this book provides information on prevention, diagnosis, therapies, self-monitoring, and specialized clinics, along with practical advice.
