How does type 2 diabetes develop?

Overweight, Obesity, and Physical Inactivity You are more likely to develop type 2 diabetes if you are not physically active and are overweight or obese. Excess weight sometimes causes insulin resistance and is common in people with type 2 diabetes. The location of body fat also makes a difference. Type 2 diabetes is an impediment in the way the body regulates and uses sugar (glucose) as fuel.

This long-term (chronic) condition causes too much sugar to circulate in the bloodstream. Over time, high blood sugar levels can cause disorders of the circulatory, nervous and immune systems. Body mass index (BMI) is a number that is calculated from a person's weight and height. Most health professionals rely on BMI to assess whether their patients are overweight (BMI of 25 or greater) or obese (BMI of 30 or greater).

All overweight adults should talk to their doctor about being tested for type 2 diabetes. Before developing type 2 diabetes, most people have prediabetes, where blood sugar levels are higher than normal, but not yet high enough to be diagnosed with type 2 diabetes. People who have prediabetes have a higher risk of developing type 2 diabetes. If you have prediabetes, losing a small amount of weight if you are overweight and getting regular physical activity may reduce your risk of developing type 2 diabetes.

A lifestyle change program offered through the CDC-led National Diabetes Prevention Program can help you make those changes and keep them sustained. Through the program, you can reduce your risk of developing type 2 diabetes by up to 58% (71% if you are 60 or older). Uncontrolled type 2 diabetes can cause chronically high blood glucose levels, which can lead to several symptoms and potentially lead to serious complications. Type 2 diabetes affects many major organs, including the heart, blood vessels, nerves, eyes, and kidneys.

In type 2, the pancreas doesn't make enough insulin, and the insulin it produces doesn't always work as it should. While there are some risk factors for type 2 diabetes that are out of your control (such as your age and heredity, as mentioned above), there are certain lifestyle options that may also put you at higher risk of developing type 2 diabetes. If you have type 2 diabetes, your body doesn't use insulin well and can't maintain normal blood sugar levels. Type 2 diabetes used to be known as adult-onset diabetes, but both type 1 and type 2 diabetes can begin during childhood and adulthood.

Controlling blood glucose, blood pressure and cholesterol, and quitting smoking if you smoke, are important ways to manage type 2 diabetes. Type 2 diabetes is a chronic medical condition in which levels of sugar, or glucose, build up in the bloodstream. If you were recently diagnosed with type 2 diabetes, ask your doctor these questions at your next visit. However, with type 2 diabetes, the body's cells can't respond to insulin as well as they should.

Over time, the pancreas cannot keep up and blood sugar rises, which lays the foundation for prediabetes and type 2 diabetes. For people with prediabetes, metformin (Fortamet, Glumetza or others), an oral medication for diabetes, may be prescribed to reduce the risk of type 2 diabetes. More than 37 million Americans have diabetes (about 1 of each, and about 90-95% of them have type 2 diabetes). Type 2 diabetes is a disease in which the body does not produce enough insulin and cannot use sugar as it should.

If you've been diagnosed with type 2 diabetes, talk to your doctor about developing a treatment plan that fits your lifestyle. .
