Type 1 diabetes, previously named juvenile diabetes or insulin-dependent diabetes, is believed to be caused by an autoimmune reaction in which the body mistakenly attacks normal beta cells, which produce insulin in the pancreas. This type of diabetes is usually diagnosed in children but can develop later. Currently, there is no known prevention for type 1 diabetes.
Type 2 diabetes is more common in older people, but it can affect individuals of all ages. In most people with type 2 diabetes, the pancreas produces insulin but the body cannot use it effectively. Type 2 diabetes can be prevented or delayed by maintaining a healthy weight, eating a balanced diet, and exercising regularly.
Type 2 diabetes is becoming more common and certain conditions can put you at risk. Risk factors include:
- Age 35 or older
- Those who are overweight or obese and have certain risk factors:
- Family history (parent or sibling) of type 2 diabetes
- Native American, African American, Latino, Asian American, or Pacific Islander race or ethnicity
- History of heart disease or stroke
- High blood pressure
- Low HDL cholesterol (the “good” cholesterol) and/or high triglyceride level
- Being physically inactive
- Having polycystic ovarian syndrome (PCOS)
- History of gestational diabetes
- Prediabetes, which is an elevated blood glucose level that is not high enough to be considered type 2 diabetes
- HIV positive
