Aims/IntroductionThe changes in metabolic parameters in type 2 diabetic patients who fast during Ramadan have not been studied in Singapore. This study aimed to examine the trends of glycated hemoglobin (HbA1c), systolic blood pressure, low‐density lipoprotein cholesterol, and triglycerides in diabetic patients with varying degrees of glycemic control and different types of therapeutic approaches during Ramadan.MethodsThe present retrospective study used a national electronic database to examine the metabolic parameter of Malay patients with type 2 diabetes. Eligible patients were stratified into three groups based on their mean HbA1c control before Ramadan: group 1 (HbA1c ≥10%), group 2 (HbA1c 7.1–9.9%) and group 3 (HbA1c ≤7%). Patients with a glomerular filtration rate <15 mL/min were excluded. The trends of metabolic parameters were traced before, during and after Ramadan.ResultsOf 13,565 patients examined, 5,172 patients (38.1%) were eligible for this study. Mean change of HbA1c varied from −1.4% to +0.2% during Ramadan, with the greatest reduction observed in group 1 (P < 0.001). A minimal systolic blood pressure reduction was observed in groups 2 and 3 (2 mmHg; P < 0.01). Low‐density lipoprotein cholesterol and triglycerides changes were insignificant. A small, 0.1%, reduction in mean HbA1c was observed in patients taking oral antidiabetic agents during Ramadan (P < 0.001).ConclusionsBlood glucose was most affected during Ramadan, particularly in patients with mean baseline HbA1c ≥10%. The type of antidiabetic agent used did not seem to contribute to glycemic changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
