Question: How to prevent Am I at Risk for Type 2 Diabetes? Taking Steps to Lower Your Risk of Getting Diabetes ?
Answer: Yes. The results of the Diabetes Prevention Program (DPP) proved that weight loss through moderate diet changes and physical activity can delay or prevent type 2 diabetes. The DPP was a federally funded study of 3,234 people at high risk for diabetes. This study showed that a 5-to 7-percent weight loss, which for a 200-pound person would be 10 to 14 pounds, slowed development of type 2 diabetes. People at High Risk for Diabetes DPP study participants were overweight and had higher than normal levels of blood glucose, a condition called prediabetes. Many had family members with type 2 diabetes. Prediabetes, obesity, and a family history of diabetes are strong risk factors for type 2 diabetes. About half of the DPP participants were from minority groups with high rates of diabetes, including African Americans, Alaska Natives, American Indians, Asian Americans, Hispanics/Latinos, and Pacific Islander Americans. DPP participants also included others at high risk for developing type 2 diabetes, such as women with a history of gestational diabetes and people age 60 and older. Approaches to Preventing Diabetes The DPP tested three approaches to preventing diabetes: - Making lifestyle changes. People in the lifestyle change group exercised, usually by walking 5 days a week for about 30 minutes a day, and lowered their intake of fat and calories. - Taking the diabetes medicine metformin. Those who took metformin also received information about physical activity and diet. - Receiving education about diabetes. The third group only received information about physical activity and diet and took a placeboa pill without medicine in it. People in the lifestyle change group showed the best outcomes. But people who took metformin also benefited. The results showed that by losing an average of 15 pounds in the first year of the study, people in the lifestyle change group reduced their risk of developing type 2 diabetes by 58 percent over 3 years. Lifestyle change was even more effective in those age 60 and older. People in this group reduced their risk by 71 percent. But people in the metformin group also benefited, reducing their risk by 31 percent.

The DPPOS has continued to follow most DPP participants since the DPP ended in 2001. The DPPOS showed that 10 years after enrolling in the DPP, - people in the lifestyle change group reduced their risk for developing diabetes by 34 percent - those in the lifestyle change group age 60 or older had even greater benefit, reducing their risk of developing diabetes by 49 percent - participants in the lifestyle change group also had fewer heart and blood vessel disease risk factors, including lower blood pressure and triglyceride levels, even though they took fewer medicines to control their heart disease risk - the metformin group reduced the risk of developing diabetes by 18 percent Even though controlling your weight with lifestyle changes is challenging, it produces long-term health rewards by lowering your risk for type 2 diabetes, lowering your blood glucose levels, and reducing other heart disease risk factors.

Type 1 Diabetes Type 1 diabetes, formerly called juvenile diabetes, is usually first diagnosed in children, teenagers, and young adults. In this type of diabetes, your pancreas can no longer make insulin because your bodys immune system has attacked and destroyed the cells that make it. Treatment for type 1 diabetes includes taking insulin shots or using an insulin pump, making wise food choices, being physically active on a regular basis, controlling blood pressure and cholesterol, and, for some, taking aspirin daily. Gestational Diabetes Gestational diabetes is a type of diabetes that develops only during pregnancy. Hormones produced by your placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If your pancreas cant produce enough insulin, gestational diabetes occurs. As with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk. Gestational diabetes occurs more often in some ethnic groups and among women with a family history of diabetes. Although gestational diabetes usually goes away after the baby is born, a woman who has had gestational diabetes is more likely to develop type 2 diabetes later in life. Babies born to mothers who had gestational diabetes are also more likely to develop obesity and type 2 diabetes as they grow up.
