Diabetes information and testing information VERY helpful

Types of Diabetes

The three main kinds of diabetes are type 1, type 2, and gestational diabetes.

Type 1 Diabetes

Type 1 diabetes, formerly called juvenile diabetes or insulin-dependent diabetes, is usually first diagnosed in children, teenagers, or young adults. In this form of diabetes, the beta cells of the pancreas no longer make insulin because the body's immune system has attacked and destroyed them. Treatment for type 1 diabetes includes taking insulin shots or using an insulin pump, making wise food choices, exercising regularly, taking aspirin daily (for some), and controlling blood pressure and cholesterol.

Type 2 Diabetes

Type 2 diabetes, formerly called adult-onset or noninsulin-dependent diabetes, is the most common form of diabetes. People can develop type 2 diabetes at any age, even during childhood. This form of diabetes usually begins with insulin resistance, a condition in which fat, muscle, and liver cells do not use insulin properly. At first, the pancreas keeps up with the added demand by producing more insulin. In time, however, it loses the ability to secrete enough insulin in response to meals. Being overweight and inactive increases the chances of developing type 2 diabetes. Treatment includes taking diabetes medicines, making wise food choices, exercising regularly, taking aspirin daily, and controlling blood pressure and cholesterol.

Gestational Diabetes

Some women develop gestational diabetes during the late stages of pregnancy. Although this form of diabetes usually goes away after the baby is born, a woman who has had it is more likely to develop type 2 diabetes later in life. Gestational diabetes is caused by the hormones of pregnancy or a shortage of insulin.

Should I be tested for diabetes?

Anyone 45 years old or older should consider getting tested for diabetes. If you are 45 or older and overweight (see BMI chart), it is strongly recommended that you get tested. If you are younger than 45, overweight, and have one or more of the risk factors, you should consider testing. Ask your doctor for a fasting blood glucose test or an oral glucose tolerance test. Your doctor will tell you if you have normal blood glucose, pre-diabetes, or diabetes.

What does it mean to have pre-diabetes?

It means you are at risk for getting type 2 diabetes and heart disease. The good news is if you have pre-diabetes you can reduce the risk of getting diabetes and even return to normal blood glucose levels. With modest weight loss and moderate physical activity, you can delay or prevent type 2 diabetes. If your blood glucose is higher than normal but lower than the diabetes range (what we now call pre-diabetes), have your blood glucose checked in 1 to 2 years.

Besides age and overweight, what other factors increase my risk for type 2 diabetes?

To find out your risk for type 2 diabetes, check each item that applies to you.

	I have a parent, brother, or sister with diabetes.
	My family background is African American, American Indian, Asian American, Pacific Islander, or Hispanic American/Latino.
	I have had gestational diabetes, or I gave birth to at least one baby weighing more than 9 pounds.
	My blood pressure is 140/90 or higher, or I have been told that I have high blood pressure.
	My cholesterol levels are not normal. My HDL cholesterol ("good" cholesterol) is 35 or lower, or my triglyceride level is 250 or higher.
	I am fairly inactive. I exercise fewer than three times a week.

What can I do about my risk?

You can do a lot to lower your chances of getting diabetes. Exercising regularly, reducing fat and calorie intake, and losing weight can all help you reduce your risk of developing type 2 diabetes. Lowering blood pressure and cholesterol levels also help you stay healthy.

If you are overweight

Then take these steps:

Reach and maintain a reasonable body weight.

Make wise food choices most of the time.

Be physically active every day.

If you checked

I am fairly inactive.

Then take this step:

Be physically active every day.

If you checked

My blood pressure is 140/90 or higher.

Then take these steps:

Reach and maintain a reasonable body weight.

Make wise food choices most of the time.

Reduce your intake of salt and alcohol.

Be physically active every day.

Talk to your doctor about whether you need medicine to control your blood pressure.

If you checked

My cholesterol levels are not normal.

Then take these steps:

Make wise food choices most of the time.

Be physically active every day.

Talk to your doctor about whether you need medicine to control your cholesterol levels. 

Doing My Part: Getting Started

Making big changes in your life is hard, especially if you are faced with more than one change. You can make it easier by taking these steps:

Make a plan to change behavior.

Decide exactly what you will do and when you will do it.

Plan what you need to get ready.

Think about what might prevent you from reaching your goals.

Find family and friends who will support and encourage you.

Decide how you will reward yourself when you do what you have planned.

Your doctor, a dietitian, or a counselor can help you make a plan. Here are some of the areas you may wish to change to reduce your risk of diabetes.

Reach and Maintain a Reasonable Body Weight

Your weight affects your health in many ways. Being overweight can keep your body from making and using insulin properly. It can also cause high blood pressure. The DPP showed that losing even a few pounds can help reduce your risk of developing type 2 diabetes because it helps your body use insulin more effectively. In the DPP, people who lost between 5 and 7 percent of their body weight significantly reduced their risk of type 2 diabetes. For example, if you weigh 200 pounds, losing only 10 pounds could make a difference.

Body mass index (BMI) is a measure of body weight relative to height. You can use BMI to see whether you are underweight, normal weight, overweight, or obese. Use the body mass index table to find your BMI.

Find your height in the left-hand column.

Move across in the same row to the number closest to your weight.

The number at the top of that column is your BMI. Check the word above your BMI to see whether you are normal weight, overweight, or obese.

If you are overweight or obese, choose sensible ways to get in shape:

Avoid crash diets. Instead, eat less of the foods you usually have. Limit the amount of fat you eat.

Increase your physical activity. Aim for at least 30 minutes of exercise most days of the week.

Set a reasonable weight-loss goal, such as losing 1 pound a week. Aim for a long-term goal of losing 5 to 7 percent of your total body weight.

Make Wise Food Choices Most of the Time

What you eat has a big impact on your health. By making wise food choices, you can help control your body weight, blood pressure, and cholesterol.

Take a hard look at the serving sizes of the foods you eat. Reduce serving sizes of main courses (such as meat), desserts, and foods high in fat. Increase the amount of fruits and vegetables.

Limit your fat intake to about 25 percent of your total calories. For example, if your food choices add up to about 2,000 calories a day, try to eat no more than 56 grams of fat. Your doctor or a dietitian can help you figure out how much fat to have. You can check food labels for fat content too.

You may also wish to reduce the number of calories you have each day. People in the DPP lifestyle modification group lowered their daily calorie total by an average of about 450 calories. Your doctor or dietitian can help you with a meal plan that emphasizes weight loss.

Keep a food and exercise log. Write down what you eat, how much you exercise--anything that helps keep you on track.

When you meet your goal, reward yourself with a nonfood item or activity, like watching a movie.

Be Physically Active Every Day

Regular exercise tackles several risk factors at once. It helps you lose weight, keeps your cholesterol and blood pressure under control, and helps your body use insulin. People in the DPP who were physically active for 30 minutes a day 5 days a week reduced their risk of type 2 diabetes. Many chose brisk walking for exercise.

If you are not very active, you should start slowly, talking with your doctor first about what kinds of exercise would be safe for you. Make a plan to increase your activity level toward the goal of being active for at least 30 minutes a day most days of the week.

Choose activities you enjoy. Here are some ways to work extra activity into your daily routine:

Take the stairs rather than an elevator or escalator.

Park at the far end of the lot and walk.

Get off the bus a few stops early and walk the rest of the way.

Walk or bicycle instead of drive whenever you can.

Take Your Prescribed Medications

Some people need medication to help control their blood pressure or cholesterol levels. If you do, take your medicines as directed. Ask your doctor whether there are any medicines you can take to prevent type 2 diabetes.

Hope Through Research

People can prevent type 2 diabetes through weight loss, regular exercise, and lowering their intake of fat and calories. Researchers are intensively studying the genetic and environmental factors that underlie the susceptibility to obesity, pre-diabetes, and diabetes. As they learn more about the molecular events that lead to diabetes, they will develop ways to prevent and cure the different stages of this disease. People with diabetes and those at risk for it now have easier access to clinical trials that test promising new approaches to treatment and prevention.
