Causes of type 2 diabetes: genetics, environment and lifestyle

When it comes to type 2 diabetes, there is no single cause. In fact, it can be a combination of factors that lead to type 2 diabetes. Here is a look at some of the factors associated with type 2 diabetes.

Genetics and family history

Genetics appear to play an important role in a person’s risk of developing type 2 diabetes. In fact, the link between type 2 diabetes and family history is stronger than the link between type 1 diabetes and family history, according to the American Diabetes Association.

Insulin resistance

Normally, your body uses a hormone called insulin to help the glucose in your bloodstream get into your cells so that it can be used for energy. But you can develop a condition called insulin resistance when cells in your muscle, fat, and liver don’t respond well to the action of insulin. This makes it harder for glucose, or sugar, to enter your cells.

As a result, you have too much sugar in your bloodstream. Your pancreas is working hard to compensate by producing more and more insulin, but it gets harder and harder to keep up and your blood sugar stays high. This prepares you for developing prediabetes or type 2 diabetes.

Visceral fat

A certain type of fat, called visceral fat, can increase your risk for type 2 diabetes.

You can’t see it but its fat that surrounds your internal organs, like your liver and intestines, deep inside your abdomen. While visceral fat is only about 10 percent of total body fat, it has the highest associated risk of metabolic problems, such as insulin resistance.

In fact, research suggests that people with a larger waistline who may have more of this belly fat are at higher risk for type 2 diabetes.

Sedentary lifestyle

Sitting for long periods of time can increase your risk of developing type 2 diabetes. Regular physical activity has been shown to help you better control your blood sugar.

Certain drugs

It is possible that a medicine you are taking for another medical condition predisposes you to developing type 2 diabetes.

For example, corticosteroids like prednisone are often used to treat inflammation, but they’re also associated with a risk of developing diabetes, research shows. High doses of statins, which are used to treat high cholesterol, can also increase your risk.

Other drugs that have been linked to an increased risk of developing diabetes in some cases include:

Other medicines can also raise your blood sugar levels, so it may be helpful to have a conversation with a healthcare professional if you are starting a new medicine, especially if you have other risk factors. type 2 diabetes.

It is important to note that medications should not be stopped without consulting a healthcare practitioner.

Certain medical conditions

If you have prediabetes your blood sugar is high, but not high enough to be diagnosed with diabetes. More than 84 million adults in the United States suffer from prediabetes. There are steps you can take to bring your blood sugar back to a healthy level, usually by eating nutrient-dense foods and exercising.

Other conditions that can increase your risk of developing type 2 diabetes include:

Some people mistakenly believe that just eating sugar will cause you to develop type 2 diabetes. However, this is not true.

By a 2015 study Published in the Journal of Diabetes Investigation, research shows that drinking lots of sugary drinks is associated with a greater risk of type 2 diabetes, but natural sugars, like those in fresh fruit, don’t seem to have the same effect, according to other research.

The development of diabetes depends on many other factors, such as those mentioned above.

A diet rich in nutrients and regular physical activity will improve your health on many fronts, including lowering the likelihood of developing type 2 diabetes.
