Introduction

Of the estimated 13 to 14 million people in the United States with diabetes, between 90 and 95 percent have noninsulin-dependent or type II diabetes. Formerly called adult-onset, this form of diabetes usually begins in adults over age 40, and is most common after age 55. Nearly half of people with diabetes don't know it because the symptoms often develop gradually and are hard to identify at first. The person may feel tired or ill without knowing why. Diabetes can cause problems that damage the heart, blood vessels, eyes, kidneys, and nerves.

Although there is no cure for diabetes yet, daily treatment helps control blood sugar, and may reduce the risk of complications. Under a doctor's supervision, treatment usually involves a combination of weight loss, exercise, and medication.

Randy Jackson Tackles Weight Loss, Diet, and Diabetes

Randy Jackson’s struggle with obesity began as a child in Louisiana, with its super spicy, often super-fatty cuisine. Even as an adult, Jackson still doesn't dream of sugarplums at Christmastime. Instead, he dreams of waltzing andouille sausage and grits, jigging jambalaya, and shimmying beignets and bread pudding with bourbon sauce. “For the old Dawg, a holiday party was a chance to have something to eat, drink, and be merry, but the new Randy does not drink or eat at parties,” says Jackson, 52,...

What Is Diabetes?

The two types of diabetes, insulin-dependent (type 1) and noninsulin-dependent (type 2), are different disorders. While the causes, short-term effects, and treatments for the two types differ, both can cause the same long-term health problems. Both types also affect the body's ability to use digested food for energy. Diabetes doesn't interfere with digestion, but it does prevent the body from using an important product of digestion, glucose (commonly known as sugar), for energy.

After a meal the digestive system breaks some food down into sugar. The blood carries the sugar throughout the body, causing blood sugar levels to rise. In response to this rise the hormone insulin is released into the bloodstream to signal the body tissues to metabolize or burn the sugar for fuel, causing blood sugar levels to return to normal. A gland called the pancreas, found just behind the stomach, makes insulin. Sugar the body doesn't use right away goes to the liver, muscle, or fat for storage.

In someone with diabetes, this process doesn't work correctly. In people with type 1 diabetes, the pancreas doesn't produce insulin. This condition usually begins in childhood. People with this kind of diabetes must have daily insulin injections to survive.

In people with type 2 diabetes the pancreas usually produces some insulin, but the body doesn't respond very well to the insulin signal and, therefore, doesn't metabolize the sugar properly, a condition called insulin resistance. Insulin resistance is an important factor in type 2 diabetes.

Points to Remember

  • Diabetes interferes with the body's use of food for energy.
  • While type 1 and type 2 diabetes are different disorders, they can cause the same 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.
