Type 2 Diabetes Risk Factors

A person with some or all of the following listed health risk factors may never develop type 2 diabetes. However, the latest medical findings show that the chances of getting type 2 diabetes increase the more health risk factors you have.

A family history of diabetes. If a parent or sibling in your family has diabetes, your risk of developing type 2 diabetes increases.
Age over 45. The chance of getting type 2 diabetes increases with age.
Race or ethnic background. The risk of type 2 diabetes is greater in Hispanics, blacks, Native Americans, and Asians.
Metabolic syndrome (also called insulin resistance syndrome)
Being overweight. If you are overweight, defined as a body mass index (BMI) greater than 25, you're at higher risk of type 2 diabetes.
Hypertension. High blood pressure increases the risk of developing type 2 diabetes.
Abnormal cholesterol levels. HDL ("good") cholesterol levels under 35 mg/dL (milligrams per deciliter) and/or a triglyceride level over 250 mg/dL increases your risk of type 2 diabetes.
History of gestational diabetes. Getting diabetes during pregnancy or delivering a baby over nine pounds can increase your risk of type 2 diabetes.
