Evidence-based case report: acute diabetic complication risks of Ramadan fasting in type 2 diabetics.

AIM: to investigate causal relationship between Ramadan fasting and acute diabetic complications in adult controlled type 2 diabetics. METHODS: a Pubmed's Clinical Queries and Embase search was conducted and resulted in 2 useful articles: 1 systematic review and 1 cohort study to be critically appraised. RESULTS: the incidence of acute diabetic complications is higher during Ramadan, with the relative risk for adult type 2 diabetics who fast during Ramadan is 1.36 and number needed to harm 50. CONCLUSION: Ramadan fasting was related with acute diabetic complications in adult controlled type 2 diabetics, but the risk was only slightly higher. It is acceptable for type 2 diabetics to fast during Ramadan.
