"If you look at the nationwide data, it's sobering," says Enrico Cagliero, MD, a diabetes researcher and assistant professor of medicine at Harvard Medical School. "A lot of diabetic patients are missing essential checks."
"People with diabetes should know that complications aren't inevitable," Cagliero says. "Unfortunately, we still see a lot of complications, and a lot of those could have been prevented. It's absolutely essential to get into this preventive mode as soon as possible. It definitely pays down the road."
Don't miss these diabetes tests.
Diabetes Test #1: Hemoglobin A1c
This diabetes blood test, also called HbA1c, tells you and your doctor how well diabetes is managed over time. It measures your average blood sugar in the previous three months to see if it has stayed within a target range.
Here's how this test works. Your red blood cells contain hemoglobin, which allows cells to transport oxygen to tissues. As a cell ages, the hemoglobin becomes increasingly "glycated," meaning that more glucose molecules stick to it. Higher glucose levels in the blood mean higher glycated hemoglobin, which translates into a greater HbA1c reading.
Normal HbA1c is 5% or less.
An HbA1c value above 7% means diabetes is poorly controlled. People with diabetes should aim for an HbA1c value below 7%.
You don't need to fast or prepare for an HbA1c test. Ask your doctor how often you need to be tested. Doctors usually recommend every 3 to 6 months.
Keeping blood sugar under control has been proven to reduce risk of complications. In the landmark, 10-year Diabetes Control and Complications Trial (DCCT), researchers studied how careful blood sugar control affected the rate of complications from type 1 diabetes. Among 1,441 subjects, those who received intensive treatment to achieve tight blood sugar control had an average HbA1c of about 7%, while those on standard therapy averaged about 9%. The group with tight control had much lower risk of complications:

Your level is currently
If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.
People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.
Congratulations on taking steps to manage your health.
However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.
Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.
Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.
One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
