Human: My doctor says that I'm at risk for diabetes. What does that mean and what should I do about it? Assistant: 
Diabetes is a condition in which the body cannot properly process glucose, or sugar. It is characterized by high blood sugar levels due to insufficient production of insulin or an inability of the cells to respond to insulin. High blood sugar can lead to serious health problems such as heart disease, stroke, blindness, kidney failure, and nerve damage. If you have been diagnosed with prediabetes, your doctor may recommend lifestyle changes such as eating healthier foods, exercising regularly, and monitoring your blood sugar level.
