Diabetes mellitus and its complications have proven to be parts of the major public health problems in Finland and it has called for the need to carry out research works on how to minimize these problems. The main purpose of this thesis is to produce information about prevention of diabetes mellitus complications among adults and the aim is to produce a guide for the public use in Terveysnetti pages. Systematic literature review was used to analyse the data.
In this research, thirty recent jounals were reviewed and five books were included. Academic databses such as Ebsco, Sciencedirect, OVID and Cinahi were used as sources of data. The study was based on the adults but the beneficiaries of the result could be any class. In the end, it was realized that efforts should be continuously made, in preventing the complications, rather than focusing on the treatment of the complications. Health information about how to prevent diabetes mellitus complication is given and the guide is developed separately. Possible researchable topics in the field of diabetes mellitus are also suggested as research areas for the future health students.
