Abstract
BACKGROUND: Type 2 diabetes is the most common diabetes in the world and constitutes a high percentage of diabetes cases. This study aims to determine the overall prevalence of gastrointestinal complaints in Iranian patients with type 2 diabetes. METHODS: The articles were extracted based on entry and exit criteria by searching the Cochrane (Embase), ScienceDirect databases. Scopus PubMed; And Web of Science (WoS), based on PRISMA 2009. To evaluate the studies, a 22-item STROBE checklist was selected and related items were used. RESULTS: The probability of publication bias in reporting the results was examined by the Egger test (P = 0.891). The prevalence rate of gastrointestinal complaints in patients with type 2 diabetes in Iran in 10 studies was 52.3% (95% CI: 33.4-70.7%). The results of metargression showed a significant difference between the sample size and the prevalence of gastrointestinal complaints in patients with type 2 diabetes (P < 0.05). and the prevalence of gastrointestinal complaints in patients with type 2 diabetes. CONCLUSION: The results of this study report that, the prevalence of gastrointestinal complications in type 2 diabetes patients was high. As a result, appropriate measures should be taken to improve the condition of diabetic patients through appropriate policy-making and providing feedback to hospitals and patients.
