People with Type 1 diabetes don’t make any insulin and must take it as a shot (injected medication). Type 1 is more common in children. People with Type 2 usually make insulin but it is either not enough or it is used poorly by the body.
Type 2 is the most common type of diabetes, and is usually seen in adults. But overweight younger people are also at risk. Before Type 2 diabetes develops a person typically has prediabetes, sometimes referred to as insulin resistance, impaired glucose tolerance, or borderline diabetes. Some women during pregnancy develop gestational diabetes. This puts them at higher risk for Type 2 diabetes later in life.
Most people can prevent or delay Type 2 diabetes with simple improvements in eating and by increasing physical activity. People can manage diabetes by working with a team of health professionals, taking medicines as prescribed and continuing to eat healthy and stay physically active.
