There are three main types of diabetes: Type 1, Type 2, and gestational diabetes. Type 1 diabetes occurs when the immune system attacks and destroys the insulin-producing cells in the pancreas. It accounts for 5-10% of diabetes cases and treatment requires lifelong insulin administration via injections or pump. Psychological impacts of Type 1 diabetes can include depression, stress, low self-esteem, and social anxiety. Higher levels of depression, stress, and social anxiety are associated with poorer diabetes management and control. Social support from family, friends, and medical providers is important for helping adolescents cope with Type 1 diabetes.
