Objective: Level of glycaemic management is critical in a surgical patient. The current research will manage in the surgical patients the diabetes mellitus.Study Design: Cross Sectional Study place and duration: The current research was carried out from January 2018 to March 2018 at Outpatient Department of Medicine at Lahore General Hospital, Lahore, Pakistan.Materials and Methods: There were 200 participants of the study.

HbA1C ranged was from 5.60-10 with mean 8.1 ± 0.45. The range for Random Blood Sugar was 139-510 mg/dl with mean 281.1 ± 77. Fasting Blood Sugar was ranging from 121-231 mg/dl with mean 129.12 ± 24. All the participants were on insulin therapy after the examination and discontinuation of oral hypoglycaemic drug in order to avoid surgery complication.Conclusion: Pre and Post surgery the main problem is the uncontrolled Diabetes Mellitus, the complications can be lessened with the close communication between surgeon, physician and anaesthetic staff. The controlling of glycaemic before operation and blood glucose after operation are important for lessening the complication. In order to perform a better surgery, electrolyte status and acid base balance must be monitored.Key Words: anaesthesia, Diabetes Mellitus Surgery, Glycosylated haemoglobin, Insulin, Oral hypoglycaemic agents, Preoperative care
