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.
