Type 2 diabetes prevention

  • While genetics plays an important role, an individual still has the ability to influence their health to prevent diabetes.
  • Obesity and a sedentary lifestyle are the biggest risk factors that are controllable. People should watch their weight, and exercise more.
  • Diet is important because it helps with weight loss. There are some foods such as nuts, which in small amounts provide health benefits in blood sugar regulation.
  • There are tests available to see if a person is at an increased risk for type 2 diabetes, but to identify the two main factors simply requires a good family history (genetics) and a bathroom scale.
  • 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. Use of these medications requires a detailed discussion of pros and cons with a doctor as there are side effects to consider.
  • 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.

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 toleranceor 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; in the Diabetes Prevention Program study, about 11% of people with pre-diabetes developed Type II diabetes each year during the three-year follow-up time of the study.

Doctors generally use one of two different blood tests to diagnose diabetes and pre-diabetes. One is called the fasting plasma glucose test (FPG), in which a person's blood glucoselevel is measured first thing in the morning before breakfast. The normal fasting blood glucoselevel 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 is considered to have diabetes.
