Diagnosing Diabetes - Testing for Type 2 Diabetes

Symptoms of Type 2 Diabetes
- Common early warning signs include extreme thirst, frequent urination, increased hunger, tingling in hands or feet, blurry vision, itchy skin, wounds that are slow to heal (particularly on the feet), and a constant fatigued feeling.
- Some people do not show symptoms, or symptoms are mild enough that they may not know anything is wrong. People can be diabetic for years without being diagnosed! This is why it's important that you see your doctor for a complete assessment. Untreated diabetes can lead to further health complications.
- Although sometimes called adult-onset diabetes, Type 2 diabetes is being diagnosed more and more often in children and teens. If you or someone you know is showing signs of diabetes, it's important to consult with your healthcare provider regardless of your age.
Family History
- Family history plays a strong role in your risk of developing Type 2 diabetes. It is believed that the closer the family link, the higher the risk. For example, if you have a sibling (brother or sister) with diabetes, your risk is strongest. The next highest risk is a parent with diabetes, then a grandparent with diabetes, etc.
Lifestyle Risk Factors
- Obesity is a strong risk factor. Even being overweight leads to insulin resistance, a pre-cursor to the development of diabetes.
- Lack of exercise / sedentary lifestyle.
- Poor diet, which can lead to weight gain.
Additional Risk Factors
- Age. People over 50 are at increased risk.
- Ethnicity. Some groups appear to be at higher risk, including Asian Americans, African Americans, Native Americans, Latin / Hispanic, and Pacific Islanders.
- Having had gestational diabetes.
- High blood pressure, cholesterol, or triglycerides.
Diabetes Testing
Your doctor may order one or more of these tests:
- Fasting blood glucose - your blood glucose levels are measured after you fast (don't eat) for a minimum of 8 hours. A normal blood glucose range is from 70 mg/dl to 100 mg/dl; pre-diabetic range is considered from 101 mg/dl to 125 mg/dl; and diabetic is 126 mg/dl and above.
- Oral glucose tolerance - you are given a sugary drink to consume. Your blood glucose levels are measured 5 times over 3 hours. In people without diabetes, blood sugar levels will rise after consuming the drink, but will quickly decrease back to normal. In diabetics, blood sugar levels will rise higher than normal and take longer to decrease.
- Random blood sugar test - blood glucose levels are tested randomly throughout the day, regardless of when you last ate. In people without diabetes, blood sugar doesn't vary that widely during the day. Generally, blood sugar should not rise above 200 mg/dl. Blood sugar between 140 mg/dl and 200 mg/dl may indicate pre-diabetes.
There is no such thing as a "mild" form of diabetes. Diabetes is a chronic disease that needs to be carefully managed to maintain good health. Thus, diagnosing diabetes is an important step for those who may be at risk. See your doctor immediately if you have risk factors - you may be able to delay or prevent the onset of the disease.
