Diabetes is a fastgrowing disease and a global health problem. It´s important that people with diabetes learn to manage their self-care to avoid complications, maintain a good health and get a freer life that they themselves control. The aim was to describe how nurses strengthens people with diabetes to manage their self-care. A literature study was carried through based on eight qualitative scientific articles and one quantitative scientific article. The analysis resulted into three main themes and five subthemes. The main themes were: strengthening self-care activities, relationships and patient at the center and support for self-care. Subthemes were: skills development, opportunities, control, communications and roles. This study indicates a patient/person-centred care from the perspective of individual which is consistent with the approach under development in Swedish health care today. Nurses need correct skills and required time to properly train and educate people. They also desire to gain new knowledge to educate people to a good self-care. Group-based personal education gives a good insight of the people and provides better health as well as lower costs of care due to fewer complications. Various efforts of "tools" for nurses to have in the education of people and the communication between the nurse-person functioning are crucial elements for achieving a good self-care. Nurses should be aware of the power relationship in the I-you- relationship with the person to avoid "taking over" the patient's empowerment and responsibility for their own self-care.
