However, because of differences in population characteristics, these estimates will vary across and within geopolitical zones. Despite the increase in prevalence of Type 2 Diabetes Mellitus in the country, no other systematic review has been carried out to assess diabetes treatment pattern in Nigeria. Hence, the importance of this study, as it critically reviews the disease prevalence and treatment pattern across and within geopolitical zones in Nigeria.To systematically review all prevalence and treatment studies published from January, 1998 to September, 2018. The following databases were searched for articles: PubMed Central (PMC), African Journal On Line (AJOL), Science Direct, and Connecting Repositories (CORE). Google scholar was also searched. 159 articles were identified from the databases while 12 were identified from Google Scholar. Studies that were excluded are: Studies that dealt mainly the prevalence of Type 1 Diabetes Melitus/gestational diabetes (14); studies with self reported diagnosis (12); case reports and editorials (10); studies that were not representative of the general population (7); and studies without case definitions (8) were excluded from the pool of studies to obtain 38 studies that were utilized for the review.
