ADA Guidelines
Choosing blood glucose goals can be easy. You can simply use the guidelines supported by the American Diabetes Association (ADA). These recommendations are based on the findings from research about preventing complications.
However, the ADA’s goals may not be easy for you to reach. Or they may not be right for you. Why not see what your blood glucose levels are before and after meals and compare them to the goals in the box below? Then choose a realistic goal for the short term. Perhaps you can make a few small changes to slowly lower your blood glucose levels.
ADA Blood Glucose Goals
Before meals: 70–130 mg/dl
Two hours after the first bite of a meal: less than 180 mg/dl
Things to Change to Lower Blood Glucose
• How much food you eat
• Kinds of food you eat
• Your activity level
• How much insulin or other medication you take
Write down an acceptable blood glucose range for you at this time. The range could be something like 70–200 mg/dl. This means that any reading below 70 mg/dl is too low. Anything over 200 mg/dl is higher than you want. This range includes lower blood glucose levels before meals and somewhat higher glucose levels 1–2 hours after meals. You should see the high end of the range come down as you work toward reaching your goals.
Children’s Blood Glucose Goals
Blood glucose goals for children are broader. For example, the target range may be 100–200 mg/dl. Most children under the age of 6 or 7 are not yet able to be aware of and respond to oncoming low blood glucose. So it’s important to limit episodes of low blood glucose. Tailor goals to the age and abilities of the child and be flexible with goals as the child grows.
Intensive Diabetes Management
Some people may want a more rigorous approach to setting goals and managing blood glucose. Intensive diabetes management, also referred to as IDM, can help prevent long-term complications and make you feel better every day. However, it is hard work, and it is not for everyone.
You’ll find out more about the treatments required for intensive diabetes management in chapter 13 on insulin and chapter 10 on healthy eating. For now, let’s discuss why you may or may not want to pursue intensive diabetes management.
Research behind Intensive Diabetes Management
It always seemed obvious that keeping blood glucose levels as close to normal as possible would prevent diabetes complications. Yet, researchers needed to prove it for sure. For example, what if something else related to diabetes caused the complications? What if lowering blood glucose had no effect on complications?
In recent years, two major research studies confirmed what many diabetes health professionals and people with diabetes had long suspected. The two studies are called the Diabetes Control and Complications Trial (DCCT) and the United Kingdom Prospective Diabetes Study (UKPDS).
The DCCT followed 1,441 people with type 1 diabetes for 10 years. Some people received a conventional treatment therapy of 1–2 shots of insulin a day, whereas other people received intensive diabetes therapy, which included either an insulin pump or multiple daily injections of insulin.
DCCT Results
Among those receiving intensive diabetes therapy, the following findings were made:
• Reduced the risk of developing diabetic eye disease, called retinopathy, by 76%.
• Slowed the progression of retinopathy by 54% in people who already had early signs of eye disease.
• Reduced risk of kidney disease by 50%.
• Reduced risk of nerve disease by 60%.
• Reduced risk of high cholesterol levels by 35% (a major contributor to heart disease).
Before the DCCT, many people with diabetes thought that complications would progress no matter what they did. After the DCCT, we know that way of thinking is wrong. Keeping blood glucose levels close to normal matters.
The other study—the UKPDS—followed 5,102 people with newly diagnosed type 2 diabetes for 20 years. People were treated with conventional therapy of mainly diet alone or intensive therapy of insulin or diabetes pills.
UKPDS Results
• People who on intensive therapy reduced their risk of microvascular complications, such as eye and nerve disease, by 25%.
• People who lowered their blood pressure reduced their risk of stroke by 44% and their risk of heart failure by 56%.
• Improved blood glucose control also reduced the risk of heart attacks and diabetes-related deaths.
• The long-term benefits of glucose control were seen even 10 years after the study ended.
What do all these numbers mean? Intensive management of blood glucose and blood pressure can significantly reduce your risk of diabetes complications. However, intensive diabetes management has some negatives.
Drawbacks to Intensive Diabetes Management
• It is more expensive.
• It takes more time and effort.
• You’ll have more hypoglycemia episodes. People in the DCCT using intensive diabetes management had three times as many severe low blood glucose episodes than those on the conventional treatment program. This happened because their overall blood glucose levels were much lower.
• You may gain weight. People in DCCT following intensive management tended to gain more weight than those using a conventional treatment program because they were no longer losing calories in the form of glucose in their urine. Taking more insulin also made their bodies more efficient at capturing and storing calories.
Is Intensive Management Right for You?
Are you already reaching your blood glucose and blood pressure goals? Do you firmly believe that you are doing fine without intensifying your diabetes management? Do you dislike the idea of having your life dictated by your diabetes care or schedule? If you answered yes to any of these questions, then intensive management may not be right for you.
However, if you want to reduce the long-term risk of complications, you may decide that intensive diabetes management is worth the extra effort, time, and side effects. In the end, intensive management may offer you more flexibility in your day-to-day living. You monitor your blood glucose more frequently so that you can make adjustments in your insulin dose to accommodate variety in your eating and activity patterns.
Intensive diabetes management can benefit almost anyone with diabetes. For years, women with type 1 or type 2 diabetes who were planning a pregnancy and women who developed gestational diabetes have been advised to take an intensive approach to their diabetes. It is particularly important during pregnancy to keep glucose levels close to normal to avoid problems in the development and growth of the baby.
Keep in mind, intensive diabetes management is not safe for some groups of people: children, elderly people, and people experiencing severe complications of diabetes, such as life-limiting illnesses or trouble with cognition or function.
