BACKGROUND AND AIMS: Uncontrolled diabetes has been associated with poorer clinical outcomes in COVID-19. We aimed to evaluate and assess the impact of COVID-19 pandemic on management of diabetes and challenges faced by people with diabetes in India during and after the lockdown phase. METHODS: A cross-sectional study based on an online questionnaire survey was designed. The questions collected socio-demographic details, medical and social history, and impact of the pandemic on medical and social life from 1582 participants. Linear regression was employed to evaluate association of different parameters with the change in glycemic levels. RESULTS: The frequency of clinical visits during the COVID-19 pandemic were reduced in 87.28% of participants. 92.45% of participants were able to monitor their blood glucose levels (BGLs) in which 78.42% (49.35%, 20.91%, and 8.16%) participants experienced an increase in BGL (mild, moderate, and severe respectively). Only 47.41% of participants possessed the digital glucometer at home. 69.07% of participants reported a decrease in physical activity while 46.88% reported an increase in food intake. 80.06% of participants were able to buy all medicines and 29.80% were gone for virtual consultations while 87.81% reported that they didn't have access to healthcare services. Overall, 89.47% participants experienced disruption in therapy. A highly significant correlation (r = 0.89, p = 0.0145) was found between increasing age and reporting of higher BGLs. CONCLUSION: This study provides a firsthand evidence of major disruption in diabetes care activities during and after the lockdown phase in India and increased risk of poorer clinical outcomes, if infected by SARS-CoV-2.
