Do you have diabetes? Are you struggling to live with diabetes? Are you looking for information online about diabetes? Are you unsure as to what types of foods you should now be eating to help keep a check on your glucose levels? If you have answered yes to any of these questions this article may well be of interest and benefit to you.

Diabetes is a disease in which the body does not produce or properly use insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. The cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity and lack of exercise appear to play roles.

There are 20.8 million children and adults in the United States, or 7% of the population, who have diabetes. While an estimated 14.6 million have been diagnosed with diabetes, unfortunately, 6.2 million people (or nearly one-third) are unaware that they have the disease.

In order to determine whether or not a patient has pre-diabetes or diabetes, health care providers conduct a Fasting Plasma Glucose Test (FPG) or an Oral Glucose Tolerance Test (OGTT). Either test can be used to diagnose pre-diabetes or diabetes.

With the FPG test, a fasting blood glucose level between 100 and 125 mg/dl signals pre-diabetes. A person with a fasting blood glucose level of 126 mg/dl or higher has diabetes.

In the OGTT test, a person’s blood glucose level is measured after a fast and two hours after drinking a glucose-rich beverage. If the two-hour blood glucose level is between 140 and 199 mg/dl, the person tested has pre-diabetes. If the two-hour blood glucose level is at 200 mg/dl or higher, the person tested has diabetes.

Major Types of Diabetes

Type 1 diabetes
Results from the body’s failure to produce insulin, the hormone that “unlocks” the cells of the body, allowing glucose to enter and fuel them. It is estimated that 5-10% of Americans who are diagnosed with diabetes have type 1 diabetes.

Type 2 diabetes
Results from insulin resistance (a condition in which the body fails to properly use insulin), combined with relative insulin deficiency. Most Americans who are diagnosed with diabetes have type 2 diabetes.

Gestational diabetes
Gestational diabetes affects about 4% of all pregnant women – about 135,000 cases in the United States each year.

Pre-diabetes
Pre-diabetes is a condition that occurs when a person’s blood glucose levels are higher than normal but not high enough for a diagnosis of type 2 diabetes. There are 54 million Americans who have pre-diabetes, in addition to the 20.8 million with diabetes.

The Genetics of Diabetes
You’ve probably wondered how you got diabetes. You may worry that your children will get it too. Unlike some traits, diabetes does not seem to be inherited in a simple pattern. Yet clearly, some people are born more likely to get diabetes than others.

“Our study demonstrates that interracial Asian-Caucasian couples represent a population with distinct perinatal risks, with differing risks depending upon which parent is of Asian race,” the researchers state in the American Journal of Obstetrics and Gynecology.

The findings are based on a study of 868 Asian-Caucasian couples, 3226 Asian couples, and 5575 Caucasian couples who delivered at the Lucile Packard Children’s Hospital in Stanford, California, from 2000 to 2005.
Compared to Caucasian couples, Asian-Caucasian couples were 2.4- and 2.6-times more likely to be affected by gestational diabetes, depending on whether the mother was Caucasian or Asian, Dr. Michael J. Nystrom, from Stanford University Medical Center, and colleagues found.

The risk in Asian couples, however, was even higher at 4.7-times higher than in Caucasian couple,

The results also indicate that Caucasian couples had larger babies than the other groups. The average birthweight in Caucasian couples was 3400 grams, compared with the next highest weight, 3360 grams, which was seen in Asian-mother/Caucasian-father couples.

Compared with Asian couples, Asian-mother/Caucasian-father couples were the only ones to have an increased rate of cesarean delivery.

“Further research into interracial couples may she light onto the effects of genetics vs environment on perinatal outcomes,” the team concludes.

A: Pre-diabetes is the state that occurs when a person’s blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes. About 11 percent of people with pre-diabetes in the Diabetes Prevention Program standard or control group developed type 2 diabetes each year during the average 3 years of follow-up. Other studies show that many people with pre-diabetes develop type 2 diabetes in 10 years.

Q: Is pre-diabetes the same as Impaired Glucose Tolerance or Impaired Fasting Glucose?

A: Yes. Doctors sometimes refer to this state of elevated blood glucose levels as Impaired Glucose Tolerance or Impaired Fasting Glucose (IGT/IFG), depending on which test was used to detect it.

Q: Why do we need to give it a new name? Has the condition changed?

A: The condition has not changed, but what we know about it has. We are giving IGT/IFG a new name for several reasons. Pre-diabetes is a clearer way of explaining what it means to have higher than normal blood glucose levels. It means you are likely to develop diabetes and may already be experiencing the adverse health effects of this serious condition. People with pre-diabetes are at higher risk of cardiovascular disease. People with pre-diabetes have a 1.5-fold risk of cardiovascular disease compared to people with normal blood glucose. People with diabetes have a 2- to 4-fold increased risk of cardiovascular disease. We now know that people with pre-diabetes can delay or prevent the onset of type 2 diabetes through lifestyle changes.

Q: How do I know if I have pre-diabetes?

A: Doctors can use either the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT) to detect pre-diabetes. Both require a person to fast overnight. In the FPG test, a person’s blood glucose is measured first thing in the morning before eating. In the OGTT, a person’s blood glucose is checked after fasting and again 2 hours after drinking a glucose-rich drink.

Q: How does the FPG test define diabetes and pre-diabetes?

A: Normal fasting blood glucose is below 100 mg/dl. A person with pre-diabetes has a fasting blood glucose level between 100 and 125 mg/dl. If the blood glucose level rises to 126 mg/dl or above, a person has diabetes.

Q: How does the OGTT define diabetes and pre-diabetes?

A: In the OGTT, a person’s blood glucose is measured after a fast and 2 hours after drinking a glucose-rich beverage. Normal blood glucose is below 140 mg/dl 2 hours after the drink. In pre-diabetes, the 2-hour blood glucose is 140 to 199 mg/dl. If the 2-hour blood glucose rises to 200 mg/dl or above, a person has diabetes.

Q: Which test is better?

A: According to the expert panel, either test is appropriate to identify pre-diabetes.

Q: Why do I need to know if I have pre-diabetes?

A: If you have pre-diabetes, you can and should do something about it. Studies have shown that people with pre-diabetes can prevent or delay the development of type 2 diabetes by up to 58 percent through changes to their lifestyle that include modest weight loss and regular exercise. The expert panel recommends that people with pre-diabetes reduce their weight by 5-10 percent and participate in some type of modest physical activity for 30 minutes daily. For some people with pre-diabetes, intervening early can actually turn back the clock and return elevated blood glucose levels to the normal range.

Q: Will my insurance cover testing and treatment?

A: Because all insurance plans are different, this is a difficult question to answer. However, Medicare and most insurance plans cover diabetes testing for people suspected of having diabetes. People at risk for diabetes are also at risk for pre-diabetes. Since the test is the same and the risk factors are the same for both conditions, a pre-diabetes test may be covered. It is best to consult your physician and health insurance representative with specific coverage questions.

Q: What is the treatment for pre-diabetes?

A: Treatment consists of losing a modest amount of weight (5-10 percent of total body weight) through diet and moderate exercise, such as walking, 30 minutes a day, 5 days a week. Don’t worry if you can’t get to your ideal body weight. A loss of just 10 to 15 pounds can make a huge difference. If you have pre-diabetes, you are at a 50 percent increased risk for heart disease or stroke, so your doctor may wish to treat or counsel you about cardiovascular risk factors, such as tobacco use, high blood pressure, and high cholesterol.

Q: Who should get tested for pre-diabetes?

A: If you are overweight and age 45 or older, you should be checked for pre-diabetes during your next routine medical office visit. If your weight is normal and you’re over age 45, you should ask your doctor during a routine office visit if testing is appropriate. For adults younger than 45 and overweight, your doctor may recommend testing if you have any other risk factors for diabetes or pre-diabetes. These include high blood pressure, low HDL cholesterol and high triglycerides, a family history of diabetes, a history of gestational diabetes or giving birth to a baby weighing more than 9 pounds, or belonging to an ethnic or minority group at high risk for diabetes.

Q: How often should I be tested?

A: If your blood glucose levels are in the normal range, it is reasonable to be checked every 3 years. If you have pre-diabetes, you should be checked for type 2 diabetes every 1-2 years after your diagnosis.

Q: Could I have pre-diabetes and not know it?

A: Absolutely. People with pre-diabetes don’t often have symptoms. In fact, millions of people have diabetes and don’t know it because symptoms develop so gradually, people often don’t recognize them. Some people have no symptoms at all. Symptoms of diabetes include unusual thirst, a frequent desire to urinate, blurred vision, or a feeling of being tired most of the time for no apparent reason.

Q: Should children be screened for pre-diabetes?

A: We are not recommending screening children for pre-diabetes because we don’t have enough evidence that type 2 diabetes can be prevented or delayed in children at high risk for the disease. However, a study published in the March 14, 2002, issue of the New England Journal of Medicine found 25 percent of very obese children and 21 percent of very obese adolescents had pre-diabetes. If future studies show that early intervention also works for children, a recommendation could be forthcoming.

Research has also shown that if you take action to manage your blood glucose when you have pre-diabetes, you can delay or prevent type 2 diabetes from ever developing. Together with the National Institute of Diabetes and Digestive and Kidney Diseases, the American Diabetes Association published a Position Statement on “The Prevention or Delay of Type 2 Diabetes” to help guide health care professionals in treating their patients with pre-diabetes.

There is a lot you can do yourself to know your risks for pre-diabetes and to take action to prevent diabetes if you have, or are at risk for, pre-diabetes. The American Diabetes Association has a wealth of resources for people with diabetes. People with pre-diabetes can expect to benefit from much of the same advice for good nutrition and physical activity.

Common Concerns
In this section, learn more about common concerns that people with diabetes face every day. These include what happens when you’re sick, and when you travel, should you get a flu/pneumonia shot, and dealing with feelings like anger and depression.

While the DPP also showed that some medications may delay the development of diabetes, diet and exercise worked better. Just 30 minutes a day of moderate physical activity, coupled with a 5-10% reduction in body weight, produced a 58% reduction in diabetes.

The American Diabetes Association is developing materials that will help people understand their risks for pre-diabetes and what they can do to halt the progression to diabetes and even to, “turn back the clock” In the meantime, ADA has a wealth of resources for people with diabetes or at risk for diabetes that can be of use to people interested in pre-diabetes.

Nutrition

Knowing what to eat can be confusing. Everywhere you turn, there is news about what is or isn’t good for you. Some basic principles have weathered the fad diets, and have stood the test of time. Here are a few tips on making healthful food choices for you and your entire family.

• Eat lots of vegetables and fruits. Try picking from the rainbow of colors available to maximize variety. Eat non-starchy vegetables such as spinach, carrots, broccoli or green beans with meals.
• Choose whole grain foods over processed grain products. Try brown rice with your stir fry or whole wheat spaghetti with your favorite pasta sauce.
• Include dried beans (like kidney or pinto beans) and lentils into your meals.
• Include fish in your meals 2-3 times a week.
• Choose lean meats like cuts of beef and pork that end in “loin” such as pork loin and sirloin. Remove the skin from chicken and turkey.
• Choose non-fat dairy such as skim milk, non-fat yogurt and non-fat cheese.
• Choose water and calorie-free “diet” drinks instead of regular soda, fruit punch, sweet tea and other sugar-sweetened drinks.
• Choose liquid oils for cooking instead of solid fats that can be high in saturated and trans fats. Remember that fats are high in calories. If you’re trying to lose weight, watch your portion sizes of added fats.
• Cut back on high calorie snack foods and desserts like chips, cookies, cakes, and full-fat ice cream.
• Eating too much of even healthful foods can lead to weight gain. Watch your portion sizes.

Exercise

The journey of a thousand miles begins with a single step. Exercise works the same way. Taking that first step can be hard, especially if you’ve been diagnosed with diabetes. Remember — it’s never too late. You can always improve your level of fitness.
