Type 2 diabetes occurs when your body doesn’t produce enough insulin or doesn’t use the insulin as it should. In the past, doctors thought only adults were at risk of developing type 2 diabetes. However, an increasing number of children in the United States are now being diagnosed with the disease. Doctors think this increase is mostly because more children are overweight or have obesity and are less physically active.
Prediabetes
Prediabetes means your blood glucose (also called blood sugar) levels are higher than normal. When your blood glucose levels reach a certain level, you have diabetes.
Type 1 Diabetes
Type 1 diabetes is a disease that occurs when your body doesn’t make or use the hormone insulin properly. It causes too much blood glucose (sugar) to build up in the blood.
Diabetes and Nutrition
What you eat is closely connected to the amount of sugar in your blood. The right food choices will help you control your blood sugar level and manage your diabetes.
Diabetes and Exercise
Exercise can make a real difference for people who have diabetes. Exercise can help control your weight and lower your blood sugar level.
Living With Diabetes: How a CGM Can Help
Using a continuous glucose monitoring system (CGM) can help some patients who have diabetes keep their blood glucose level from getting too high or too low.


Monitoring Your Blood Sugar Level
If you have diabetes, it’s important to monitor your blood sugar at different times of the day and throughout the year. There are 3 tools that can help you do this: A blood test done every three months, blood tests taken every day, and a system that constantly monitors your blood glucose.

Oral Medicines for Diabetes
Oral diabetes medicines are medicines that you take by mouth to help control your blood sugar level. They are designed to help people whose bodies still produce some insulin, but not enough insulin. Many categories of diabetes medicine are available in pill form.

Insulin Therapy
All people who have type 1 diabetes and some people who have type 2 diabetes need to take insulin to help control their blood sugar levels. Insulin can’t be taken by mouth. It is usually taken by injection (a shot). It can also be taken using an insulin pen or an insulin pump.
