Type 2 diabetes is a chronic condition that occurs when the body does not effectively use insulin or make enough insulin. It is the most common form of diabetes, affecting 90 to 95 percent of people living with diabetes.
What Causes Type 2 Diabetes?
Type 2 diabetes can be caused by a combination of lifestyle factors and genetics. People are at an increased risk of developing type 2 diabetes if they have a family history of the condition, are overweight or obese, lead an inactive lifestyle, and/or eat an unhealthy diet.
Genetics: Genetics play an important role in the development of type 2 diabetes. Studies have found that certain genetic variations can increase the risk of developing the condition. Research is ongoing to better understand the role of genetics in type 2 diabetes.
Lifestyle Factors: Lifestyle factors can significantly increase the risk of developing type 2 diabetes. Obesity, sedentary lifestyle, and unhealthy eating habits are major risk factors for the condition. People who are overweight or obese are much more likely to develop type 2 diabetes than those with a healthy body weight.
Other Factors: Other factors that may increase the risk of type 2 diabetes include age, ethnic background, and medical conditions such as high blood pressure, high cholesterol, and sleep apnea.
Can Type 2 Diabetes Be Prevented?
Type 2 diabetes is a preventable condition. Making healthy lifestyle changes, such as maintaining a healthy weight, getting regular physical activity, eating a healthy diet, and not smoking, can help reduce the risk of developing the condition. However, if you have a family history of the condition or any of the risk factors mentioned above, you should talk to your doctor about your risk and what steps you can take to lower it.
