Who Is at Risk?
Obesity is a major risk factor for developing diabetes. Those who have a body mass index (BMI) of 30 or higher are considered obese and are more likely to develop type 2 diabetes. This is because excess body fat can make it harder for the body to use insulin properly.
Family history of diabetes is also an important factor to consider. If you have a parent or sibling with type 2 diabetes, you are more likely to develop the condition yourself. This is because genes can influence your risk of developing diabetes, as well as your weight and lifestyle habits.
Inactivity is another risk factor for developing diabetes. Physical activity helps the body use insulin more effectively and can lower blood sugar levels. A sedentary lifestyle, on the other hand, can lead to insulin resistance and make it harder for the body to regulate blood sugar levels.
- Age: The risk of developing type 2 diabetes increases as you get older, especially after the age of 45.
- Race and ethnicity: Certain racial and ethnic groups, including African Americans, Hispanic/Latino Americans, and Asian Americans, have a higher risk of developing diabetes.
- Gestational diabetes: Women who develop gestational diabetes during pregnancy are at an increased risk of developing type 2 diabetes later in life.
- Polycystic ovary syndrome (PCOS): Women with PCOS, a hormonal disorder that affects the ovaries, are at an increased risk of developing diabetes.
- High blood pressure: Having high blood pressure can increase your risk of developing diabetes, especially if it is not well controlled.
- Abnormal cholesterol and triglyceride levels: Having low levels of HDL (or “good”) cholesterol and high levels of triglycerides can increase your risk of developing diabetes.
Knowing your risk factors for diabetes can help you make healthy lifestyle choices and take steps to prevent or manage the condition. If you are at risk for diabetes, talk to your healthcare provider about steps you can take to lower your risk and stay healthy.
