Diabetes in Men

(continued)

What is diabetes? continued...

Another driver of type 2 diabetes, also linked to the others, is inactivity. Lack of activity increases the risk of obesity, of course. But a sedentary lifestyle may contribute directly to type 2 diabetes risk, as well. Studies show that overweight or obese people who become active improve their blood sugar control, even if they don't lose weight.

An estimated 7 million people in the U.S. have this serious disease and don't know it. An estimated 79 million people have prediabetes, meaning they have elevated blood sugars not yet high enough to be diagnosed with the disease. However, with prediabetes you are at risk for diabetes in the future. It's easy for doctors to check for diabetes using a simple blood test that measures blood sugar levels or a test called a hemoglobin A1c. Unfortunately, many people aren't tested because they either don't have symptoms or the symptoms are so mild that they don't notice them. Talk to your doctor about being tested, especially if you're experiencing any of the following symptoms:

  • increased thirst
  • increased hunger
  • fatigue
  • frequent urination, especially at night
  • unexplained weight loss
  • blurred vision
  • sores that don't heal

What can I do to prevent diabetes?

Plenty. Studies show that 90% of cases of type 2 diabetes could be prevented -- or significantly delayed -- simply through a healthier diet and plenty of physical activity. The big proof of that came in a study of 3,234 people who were overweight and had elevated blood glucose levels, putting them in the crosshairs of diabetes risk. Those who followed a lifestyle change program of exercise and diet geared to losing excess weight -- in this case, an average of 15 pounds -- lowered their risk of diabetes by 58%. Those in the 60-and-older set cut their risk by 71%. And these were people who already had a high risk of diabetes. Keep your weight in the normal range and stay active, experts say, and you stand an excellent chance of never getting diabetes.

How is diabetes treated?

A diabetes diagnosis isn't the end of the world. In some cases, lifestyle changes can keep the disease entirely under control. Still, many people with diabetes need to take oral medications that lower blood sugar levels. When these aren't enough to do the job, insulin (which is inhaled and/or injected) may be necessary, sometimes in combination with oral drugs. Several new drugs that work in combination with insulin to improve blood sugar management have been approved by the FDA.

While treatment has improved, however, controlling diabetes remains a challenge, which is why experts emphasize prevention.
