Type 2 Diabetes: Learn the Warning Signs

Pre-Diabetes? Could You Have It?

About 41 million Americans between the ages of 40 and 74 have "pre-diabetes." Prediabetes is a condition that, as the name implies, can be considered an early, potentially reversible, stage in the development of Type II diabetes. Pre-diabetes is sometimes called impaired glucose tolerance or Impaired Fasting Glucose (IGT/IFG). In pre-diabetes, a person's blood sugar(glucose) levels are slightly higher than the normal range, but not high enough for a true diagnosis of diabetes. People with pre-diabetes have a significant risk of developing full-blown diabetes.

Type 2 diabetes prevention facts

  • While genetics plays an important role in the development of diabetes, an individual still has the ability to influence their health to prevent diabetes.
  • Obesity and a sedentary lifestyle are the biggest diabetes risk factors that are controllable.
  • People should watch their weight and exercise on a regular basis to help reverse pre-diabetes, and prevent the development of type 2 diabetes.
  • Diet is important because it helps with weight loss. Some foods such as nuts in small amounts provide health benefits in blood sugar regulation.
  • There is no single recommended diabetes prevention diet, but following a sound nutrition plan and maintaining a healthy weight are important steps.
  • Exercise is beneficial even without weight loss in the prevention of type 2 diabetes.
  • Exercise is even more beneficial with weight loss in the prevention of type 2 diabetes
  • Smoking is harmful in many ways including increasing the risk of cancer and heart disease. It also increases the risk of developing type 2 diabetes.
  • There are medications available that have been shown in large trials to delay or prevent the onset of overt diabetes. Metformin (Glucophage) is recommended by the American Diabetes Association for prevention of diabetes in high-risk people.
  • The coming years will be very exciting regarding the advances in the field of prevention of diabetes. However, the cornerstone of therapy will likely remain a healthy lifestyle.
