Diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes sugar to build up in your blood.
Types of Diabetes
- Pre-diabetes - Prediabetes is a condition when your blood glucose is higher than normal but not high enough to be diagnosed with diabetes. This condition puts you at risk for developing Type 2 diabetes.
- Type 1 diabetes was previously called insulin-dependent diabetes mellitus (IDDM) or juvenile-onset diabetes. It is usually caused by an auto-immune reaction where the body’s defense system attacks the cells that produce insulin.
- Type 2 diabetes was previously called non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes. This is the most common type of diabetes. In Type 2 diabetes, there may be insulin resistance and/or insulin deficiency. This type of diabetes can go undetected for many years and is usually found when a complication appears or as a result of a routine blood or urine glucose test.
- Gestational diabetes - a type of diabetes that only pregnant women get. If not treated, it can cause problems for mothers and babies. Gestational diabetes develops in 2% to 10% of all pregnancies but usually disappears when a pregnancy is over.
- Other specific types of diabetes can result from specific genetic syndromes, surgery, drugs, malnutrition, infections, and other illnesses.

Signs and Symptoms
Early detection and treatment of diabetes can decrease the risk of developing the complications of diabetes. The following symptoms of diabetes are typical:
- Urinating often
- Feeling very thirsty
- Feeling very hungry - even though you are eating
- Extreme fatigue
- Blurry vision
- Cuts/bruises that are slow to heal
- Weight loss - even though you are eating more (type 1)
- Tingling, pain, or numbness in the hands/feet (type 2)
- Very dry skin
You can prevent or delay the onset of type 2 diabetes through a healthy lifestyle.
- Change your diet - Eat Well
- Increase your level of physical activity - Move Well
- Maintain a healthy weight
Staying Healthy with Diabetes
- Measure your blood pressure
- Check your feet for sores at every doctor visit, and get a thorough foot exam at least once a year
- Have a hemoglobin A1C test at least twice a year, to determine what your average blood glucose level was for the past 2 to 3 months
- Test your urine and blood to check your kidney function at least once a year
- Test your blood lipids (fats) – total cholesterol; LDL, or low-density lipoprotein (“bad” cholesterol); HDL, or high-density lipoprotein (“good” cholesterol); and triglycerides at least once a year
- Get a dental checkup twice a year
- Get a dilated eye exam once a year
- Get an annual flu shot and a pneumonia shot
