Introduction: Covid 19 pandemic and the lockdown to contain the virus spread has thrown the world into unexpected health emergency with disruption of essential health services. The glycemic control of diabetic patients was affected because of the unavailability of drugs and lack of physician consultation. Objective: The study was carried out to evaluate the glycemic control in diabetic patients after the lockdown and its comparison with pre lockdown levels. Methods: When patients with type II diabetes mellitus start following after unlocking, will be enrolled in the study. All patients with type II diabetes mellitus follow in the clinic will be enrolled with the simple random method. More than 150 subjects will be enrolled and data collected over 2.5 months. The statistical analysis will be done by unpaired t-test and chi-square test analyzed by SPSS 19 version of the software. Results: There was a considerable increase in the interquartile range of blood sugar levels with 144.75- 207.50 and 162.0- 198.50 before and after lockdown (p__ampersandsignlt;0.05). The increase in median postprandial sugar levels was more pronounced in males than in females. A significant increase in blood sugar levels was noted in patients who were not on medication, with blood sugars almost double compared with the pre lockdown period. The median sugar levels increased from 181mg/dl to 225 mg /dl in pa tients who were not able to exercise during the period of lockdown and the difference was found to be significant (P-value __ampersandsignlt;0.05). Conclusion: Our study showed that postprandial blood sugar levels were deranged during the 45 days lockdown. Some factors like lack of exercise, non-availability of medications during the lockdown led to deranged glycemic levels and in turn increase in medication in the post lockdown period is worrisome.
