What is type 2 diabetes? Type 2 diabetes is when your body doesn’t use insulin properly. In type 2 diabetes, some people are insulin resistant, meaning that their body produces a lot of insulin but can’t use it effectively. Some people with type 2 diabetes don’t produce enough insulin. Type 2 is different from type 1 diabetes because in type 1, your body doesn’t produce any insulin at all.
Whether you’re insulin resistant or have too little insulin, the end result is the same in type 2 diabetes: your blood glucose level is too high.
What are the symptoms of type 2 diabetes?
The symptoms of type 2 diabetes (also called type 2 diabetes mellitus) develop gradually—so gradually, in fact, that it’s possible to miss them or to not connect them as related symptoms. Some of the common symptoms of type 2 diabetes:
- Extreme thirst
- Frequent urination
- Extreme hunger
- Weight loss
- Frequent infections
- Slow wound healing
- Blurry vision

What causes type 2 diabetes?
Type 2 diabetes has several causes: genetics and lifestyle are the most important ones. A combination of these factors can cause insulin resistance, when your body doesn’t use insulin as well as it should. Insulin resistance is the most common cause of type 2 diabetes.
What are the risk factors for type 2 diabetes?
Type 2 diabetes has many risk factors associated with it, mostly related to lifestyle choices. But in order to develop insulin resistance (an inability for your body to use insulin as it should) and type 2 diabetes, you must also have a genetic abnormality. Along the same lines, some people with type 2 diabetes don’t produce enough insulin; that is also due to a genetic abnormality.
That is, not everyone can develop type 2 diabetes. Additionally, not everyone with a genetic abnormality will develop type 2 diabetes; these risk factors and lifestyle choices influence the development.
Other risk factors for type 2 diabetes include:
- Family history: Type 2 diabetes has a hereditary factor. If someone in your close family has (or had) it, you are more likely to develop it.
- Race/ethnicity: Certain ethnic groups are more likely to develop type 2 diabetes, including African-Americans, Hispanic Americans, Native Americans, and Asian Americans.
- Age: The older you are, the more at risk you are for developing type 2 diabetes.
- Gestational diabetes: If you developed diabetes while you were pregnant, that increases your risk for developing type 2 diabetes later on.
- Other health problems: High blood pressure (hypertension) and high cholesterol (the “bad” LDL cholesterol) increase your risk of developing type 2 diabetes complications. Polycystic ovary syndrome (PCOS) may increase your risk of developing type 2 diabetes.
How is type 2 diabetes treated?
Type 2 diabetes is treated with a combination of healthy meal planning, physical activity, medications, and perhaps insulin.
Healthy meal planning changes and exercise are the cornerstones of type 2 diabetes treatment. They often help people lose weight, which in turn can help their bodies use insulin better. Many people, when they’re first diagnosed with type 2 diabetes, are overweight (BMI >25), so making healthy lifestyle choices—such as reducing calories and portion sizes and being more active—can help them get to a healthier weight.
